As a copywriter, I wanted to give you advice about how to write the description section for an app on the iOS app store.
However if you’re searching for this info, you’re probably a bit of a nerd. And nerds like actual data, not the opinions of some random brown dude in Austin.
So we stole gathered some data for you to help you understand a little more about app description sections:
- Broke up the study into two categories: Paid Apps, and Free Apps.
- We scraped data from the Top 100 Paid iOS Apps.
- We scraped data from the Top 100 Free iOS Apps.
- App Store data was scraped on May 1st, 2016.
- Data Scraped: App name, developer name, app store ranking, price, In-App Purchases, number of promo images, current version rating, overall rating, app description, word count, and if the description contains bullet points.
You can see the raw data for both the free and paid apps by clicking these big blue buttons below (the large text blocks of descriptions make it a bit messy, my apologies):

So after learning all this, how do you write an app store description?
Quite honestly, from looking at the data, there seems to be no super-strong correlation between your app store description and the ranking you will receive. So here’s some tips to follow:
Tip #1: You “really” have less than 50 words to describe your app.
You can see evidence that a lot of people aren’t interested in the full app description by the iOS App Store snipping the amount people auto-load. This is what people generally see.
Tip #2.) Focus on your icon and promotional images….not so much the description.
The bulk of the “Downloading Decision” will come from your app icon and promotional images. These images are viewed far more than the description text.
If they are looking for a calculator…..make your calculator app icon look something like….you know, A CALCULATOR:
Don’t try to be “too clever” and design your icon as some inside joke. It can botch the users split-second “Download Decisioning.” Keep it ultra ultra ultra self-explanatory.
You can follow the same advice with your promotional images (almost all the Top 100 apps have 5 promotional images). Make sure they clearly demonstrate what your app does either through screenshots or demonstrations.
Here’s a good “demonstration” example by Duet Display, who shows some features and testimonials of the app right inside the promotional images:
Here’s a “screenshots” example of the game War Tortoise where it just shows screenshots of the game:
Tip #3: Find inspiration from reading some other Top 100 app descriptions:

P.S. I need help sifting through the data. What other findings can you see? What other examples would help you better? Comment below and lemme know (that totally rhymed)!
Thanks Neville! I know this post had been posted a couple of months back, but this is a really great starting point on how we should strategize writing app descriptions in the future.
You’re awesome!
Whoops never mind, I thought these orange boxes should contain the 5 most used images. What is sort of bs. Haha. Thanks for the article.
Thanks for your helpful article. I read it from the first word to the last point. Even the longest description is rather captivating.
They are all pretty good…..probably a bit biased because they’re all Top 100 apps!
Top two points:
a. Number of words in description: between 100 and 200
b. Bullet points: don’t use ’em
Thanks!
Hahhaha, nice synopsis Julie! I wouldn’t necessarily rule out bullet points through. While a lot of the descriptions didn’t have them, it doesn’t mean they are BAD in this case. It was more just interesting than anything.
Also some of the descriptions used quirky bullet points:
–kinda
–like
–this
…instead of real bullet points. So don’t pay TOO MUCH heed to that stat :)
Quick clarification. Are you saying ALL top 100 paid and free only use images in app store, no videos?
Bro, you obviously know that’s not what I mean :)
Great info! Have you done any analysis on niche specific apps? I would be curious to know what traits all of the top real estate apps share.
Haven’t done anything on real estate apps. I probably won’t either. Perhaps something YOU can do?? :)
Dude, I don’t even have an app and I love this.
You are the winner of internets
Do podcasts :)
P.s. I don’t have a podcast either
I’m sure there’s a cat out there that’s winning the internets more than me right now :)
Hi
What tool do you use to scrap all of this data? This information is tremendous. I am sharing it with my team right now, wait that’s me. I really love all of your posts and information that you provide. I am a one person web team so all this helps get a little further ahead with limited resources. Love getting your emails because I am constantly learning.
Thanks
Jen
Hey Jen, there’s no single tool to scrape info. Each case is different, some of it is manual collection, some of it is scripts. Glad you enjoyed, and thanks for reading :)
Hey, Thanks for the article. Really appreciate you giving out REAL value for free. Not many people do that today and if they do i doubt it is up to this standard. Keep doing what you’re doing. Thanks
Why thank you, I try :)
.. with the EA games, they get promoted because of the same developer and appear below the description like recommendations for the user
Well…..they also make a lot of very very popular games.
Giz, this will be very helpful for too many. *Sharing Now.
– ALSO..
Here’s my comment about the data, and about other experiences I’ve been involved with launching apps.
– REVIEWS ARE TOO IMPORTANT FOR APPLE, I MEAN, REAL REVIEWS
– If you are Electronic Arts, chances your other games will be downloaded if you have (as they have) TOO MANY GAMES (some are cool)
– The description you put in your app, does work with the advertising you use (keywords and developer site), as in ALLINSEO strategy. Because, facebook and google now have targeting for apps instals exclusively.
Advice for games:
– give youtubers free apps (and of course, get them to use the apps.. that’s the challenge)
– hire some chic to do the commercials :P (https://www.youtube.com/watch?v=XkaWyrm8EQg)
That’s all (for nahow)
Thanks for sharing Salomon! In-app-description SEO definitely works, but only like it does for content on the web…..it’s a MUST HAVE, but also you MUST HAVE other promotional alleys. Simple putting “productivity tool” in an app name or description will only take you so far without other marketing.
Thanks for your input!
sure, that’s a MUST.
thanks for the response!
I try to respond to all of these. Takes a lot of time, but I still try!
Hi Nev,
Thanks for doing all of this work and analysis! I have a couple questions:
1. Do you think it is more effective to use your first 50 words for third-party endorsements and reviews? Or for your core product description?
2. What role should image captions play?
3. Do you believe the description as any impact on ASO (despite Apple’s insistence that it doesn’t)?
4. Is there any way to scrape for keywords?
Look forward to reading your newsletters!
Best,
Alex
Thank you Alex :)
1.) Saying something like “The #1 app used by residents of Seattle!!” would probably be a great thing to advertise. You can also do that in the app images which seem to get more eyeball views.
2.) They should demonstrate awesome features, and at least one slide should be dedicated to testimonials.
3.) It has SOME impact. But like normal SEO for webpages, it’s just a piece of puzzle, not the WHOLE puzzle. Promotion outside the app store is needed also. App markets will also feature apps that bring in a lot of money over ones that do not.
4.) Vague question.
Glad you like the newsletter, hope I can keep sending you cool stuff like this :)
4.)
Incredible content!!! Your data-driven approach is very impressive and clearly superior to just stating your opinion.
Great job Nev!
Very much appreciated Till :)
An opinion is great, especially since I have a decent amount of experience in this…..but data is even awesome-er.
A couple things I think might be interesting to delve in to.
1. I mainly looked at the paid apps spreadsheet because most of the free ones I already heard of and would have downloaded them no matter what the description said (I would download Instagram if the description said that this is the worst photo app in the world, but I know it from outside of the app store world so I will download it anyways)
Maybe an analysis of free apps with no associated online services would be more beneficial.
2. Most of the descriptions have testimonials. I wonder if there is a sweet spot for the number of testimonials or if they even matter.
1.) You’re 100% right on that.
2.) I doubt there’s a “sweet spot” for number of testimonials, but I’m aware that testimonials HELP.
3.) After running this data is seems like the app store description is helpful, but not crucial to an apps success. Outside marketing, number of ratings, number of users etc all seem to have a bigger impact on the success of an app.
How much of the content includes a “changelog”? I suspect quite a few description will have at least some part of the changelog. I’m also assuming that the 0-100 word count apps are the typically the big apps which already have a significant amount of traction and whose audience sustains them in the top-100 list
Do you also have stats on how many of them had a promo video?
Hey AJ, I don’t have those answers yet!
Neville, good stuff! I don’t know if I’ve seen this type of analysis before, so way to go!
I haven’t developed an app but I’m guessing developing is the easy part, the hard part is getting people to download so this has to be really important for new apps. Also, I’m sure the same type of information is relevant for Amazon and eBay, what are the top sellers doing in their titles and descriptions.
Speaking of titles, that might be something worth looking at. Many of the free app had a few word description as part of the title.
Few things I noticed glancing though the data is many of the top 100 are the well known apps (twitter, uber, google, EA etc) so I tend to question the value of those app descriptions. Not to discount them but it seems like a no name developer would be more interested in what the successful “little guys” are doing vs the big names that people may be downloading regardless of the description.
So now that you’ve done all this work :), I wonder if data apps ranked 50-150 or 100-200 would be more relevant for the newer unknown apps? Maybe I’ll do that.
It appears there were few apps with less than 3 stars with the exception of well known companies, like Starbucks. I’d assume reviews play a big part as well.
Thanks Daniel! I never saw any analysis of making app descriptions either, so I just did it :)
A number of people have suggested the same type of analysis, but quite frankly…..that seems boring as hell, so I’m probably not gonna do it! (just being honest here)….
After this experiment was done, I’ve come to the conclusion that the app description is one of the least important parts of the decision tree that people use to download apps. Therefore I probably won’t spend much more effort re-evaluating the results for all the other apps.
Thank you for the suggestion though, lemme know if you end up doing it!
Good article – one I will be referring to for ideas.
I like the raw data about using bullets – interesting fact!
Thanks Susan! Please share with anyone interested!
You must have poured in a lot of work on the data collection, Nev!
Another dimension that can be useful: Is there a correlation between the number of reviews an app has and its ranking in the app store?
If so, app developers can think about how to actively encourage reviews from its users.
I don’t THINK there is, although you could find out from the raw data!
It seems some of the apps (like SnapChat) have only 2 1/2 star ratings, yet are ranked in the top 10.
I think apps made by Facebook and Google can have low ratings but still remain in the top 100 (since those services you nearly HAVE to use)…..however if there’s a game app, it probably needs to have a high rating to stay in the top 100.
So if you really want to nerd out… Could there be a case of correlation vs causality? You do kind of address it, but with Google or EA having most of the top 100, they could write 10 words or 1000 words and skew the data. Maybe you need to take a random sample of the top 1000 apps and see if they correlate to ranking. Of course, because that wouldn’t take a whole of time…
Hahaha…..yeah a few people have suggested this, and I was originally going to do this, but I wanted to just SEE WHAT THE TOP DOGS ARE DOING.
I only wanted the data from the Top 100. I’m sure there’s other experiments within here, but so far none of them seem super interested for the amount of time they’ll take to gather & analyze & post about.
Neville,
Thanks for sharing this… I read one of the comments about a template (nice idea)…. I put together an Excel template with a word count for the different Kopy Blocks (check your NevMed email). Please feel free to share it with the Kopy Kommunity. Hope it helps.
Thanks again.
Will check it out today Jim, thank you!
You are very welcome… it is a simple setup… if you want something a little fancier (say a layered photoshop template to look like the App Store) just let me know and I will put it together.
I just sent you an updated template (complete with graphic/photo placeholders)… this way it feels more like an App Store layout. It still includes the word count. I also provided instructions with screenshots on how you can easily change the placeholder graphics to your own custom content.
I appreciate it Jim!
I am glad to help.
Have a great weekend.
Data really does trump opinion. I appreciate that you went the data route here, it’s refreshing.
One issue I do see with these data is that they only show one moment in time — May 1, 2016. Rankings can fluctuate quite a bit and so your results could be significantly different on another day. It might be interesting to do this same data scrape on multiple days over time. It might also be interesting to categorize each app type and follow them over time to see which are consistently in the top 100 and which just got lucky one day. So, for example, you would follow the apps that use long copy and follow the apps that use short copy and see which is consistently in the top 100.
If you really wanted a deeper understanding of how the copy affects sales you’d want to control for confounding variables. Big brand name vs small time developer, ratings and number of reviews, color schemes and picture quality….. categorizing apps and following them could sort this out. I’m guessing you have better things to do though. Maybe if you get bored.
Another idea would be to have a focus group rate how compelled they are to buy an app based only on the copy in front of them. Take away the pictures, reviews, app name, etc, and see if the copy converts.
Further research aside, I think with any copy the length depends on your audience and how much you’ll need to convince them to buy. Saying the average word count of all 100 apps is x is not very useful. If I am selling an app that stores your businesses data and keeps track of inventory, my copy is going to be longer than if I am selling an app that makes fart noises. Both apps could be in the top 100 on any given day, it’s not useful to average the word count on very different apps like that and say “therefore, 250 words is best.”
Lol….yeah there’s a lot of different things I could do with the data, but from the results already, I’m not sure there would be MASSIVELY big (or interesting) changes.
I think just judging an app by the copy alone is a mistake, as there’s so many other ranking factors that go into it (Ratings, Press, Images, Word of Mouth etc).
I’m not advocating that 250 words is best….but that it’s simply the most COMMON amongst the data set.
This was really interesting to read Nev! Kinda daunting to realize that the key to download success hinges much more on how professional and crisp you can make the download page look versus how it actually plays. But I suppose word of mouth and a good product will win out in the end.
Have you considered making your own app to test out different copy and strategies?
Thanks Greg!
Well I think an AMAZING APP will gain momentum if enough people like it. However, having some good marketing surrounding it definitely helps. You’re right, good word of mouth and an amazing product will win in the long run.
I haven’t considered making my own app just yet….as that may be a several-months-long experiment, and I’ve got a lot of other stuff to write about first!
Great post, Neville. Thanks for posting! Definitely got me thinking about a handful of things. First, I was reminded of Ogilvy’s quote: “On the average, five times as many people read the headline as read the body copy. When you have written your headline, you have spent eighty cents out of your dollar.” It seems that this hold with apps. The title and initial “headline” or top line words in the short and long description probably matter a lot. I would love to see some type of analysis of the top line in the descriptions. What approaches and styles do they use? Is it a headline? Description? Statistic? Testimonial?
That leads me to my next observation and question: how frequently and in what form do top 100 apps use testimonials or other influence factors, like authority positioning?
Your suggestion to focus a bit more on images is consistent with my experience as a user. I always judge an app by its cover, but still dive in a little bit to explore. I usually look at the name, peak at the short description, then flip through the images. If I like what I see, I then may read the longer description and/or the reviews. A few years ago I was quicker to download an app. Now, with so many apps, it takes more convincing to get me to spend my time checking out an app.
Finally, your analysis reveals a lot about the business models this apps are using. While this is not as related to copy, it is very interesting as an entrepreneur. I work with a lot of people trying to build apps. Most of them have no idea how they want to make it a business. They think that an app is a business by definition. This is obviously not the case. From your analysis, you get a sense of how some of these companies make money (upfront purchase, in app, and–while you didn’t look at it–ads) on their apps. Of course, others don’t use an app as a revenue or profit generator, and may be positioned as a marketing tool, supplement to their core offering, or lead-in to other products.
Thanks again for the insights and analysis.
Hi Nev,
If possible, I’d wanna see examples of app descriptions you’ve written for companies and if you have any sort of data on them as well. Yes, app descriptions do help when a user is just shopping for these apps randomly (say category wise) on the Appstore. But in most cases, people usually directly go to your Appstore page and download your app after reading/ getting to know about it from somewhere or someone.
I believe the most influential factor in helping you get app downloads is word-of-mouth and your app actually being good and helpful for the user (of course).
But always good to have these data handy for when you’re about to sit down to write app descriptions. Thanks yet again for such an insightful post.
Hey Abeniel, I totally agree…..most people will never read much of the description. I mainly made these observations just to share with other developers who I know will like the data more than an opinion of how to write a description!
> But in most cases, people usually directly go to your Appstore page and download your app after reading/ getting to know about it from somewhere or someone.
Definitely agree in this.
Having crappy descriptions/bad store page will cause a bit of friction – a “WTF”. To re-convert the user, that user needs to discover MORE social proof (one that should have been done with a good store page). A tiny moment of hesitation can mean the difference between getting the download or not.
So why leave it to chance?
Totally true Rocky! I probably didn’t convey that so well. Will probably put a template for people to follow in the post for some additional guidance.
What I usually suggest for app store descriptions is BRAGGING by showing how many ratings you have, or great testimonials from users.
It looks like the app developers did a lot of homework or hired a marketer to determine the “sweet spot” for the amount of words in the description, bullet points (if any), amount of pictures, words used for SEO, etc…. I don’t think these findings are just random, it looks like a pattern to me and obviously it is working for them. This idea of scrapping information can really be useful for many different things being sold on the internet. Thank you for doing the research and letting us know about it.
Thanks Chris! I think analyzing the actual data is important, rather than just me spouting information about how I THINK a description should be written (although I might add some of that in just as a guide to developers who don’t wanna deal with it).
I’d be really interested to hear how your opinion stacked up against the data and/or your opinion on the data.
Also, in place of the overall top 100 in paid and free, which probably include things like Facebook, it would be cool to look at newly added apps that are doing well.
Hey Lucas, one of the things that surprised me was the shortness of descriptions. I thought app developers would just use all the space they could to add positive reviews and different uses, but many of them kept it short (especially in the free section where the most common length is between 100 and 200 words)!
I originally tried looking at some of the “newly added” apps, but unfortunately there’s a lot of crappy apps too. I decided to just pull lessons from the big dawgs!
I’m extremely impressed with how much pre-work you do for some of these posts Neville. The data focused angle on this was great. I think adding some more examples to the post would help developers. Perhaps even template-tizing (is that a word?) some descriptions for them. Keep up the great work.
Thank you Ronit! I actually woke up at 5am to finish off the findings, so I appreciate that :)
I think the template is a great idea. I might actually go do that. A NevBox-worthy suggestion!
