Tips on How to Write App Descriptions That Sell Your Product

You need to write down why people should bother downloading your app before you even start building it. An app description is an app store optimized product definition. It greatly influences your product’s success.

There are three components of an app’s ‘definition’: its Name, its Description in the marketplace, and Screenshots. 

Components of an app’s definition

There is no one way to write a product definition, but there are some terrible ways to do it. To prevent disaster, we gathered some helpful how-tos specific to each part of the app page on the App Store and Google Play. Let’s look at them first briefly, and then in greater detail. 

App name

You want your customers to find your app through the search on the App Store and Google Play. The only way to make this possible is by choosing the right name for your app.

Your app’s title should reflect two or three of the app’s most significant – and differentiating – features. Limit the title to one hundred characters. You should also make sure that the title includes keywords. They help people to find your product on the App Store or Google Play Store.

App description

Keep in mind the following attributes of a great app description:

  1. The first 1-3 sentences of an app’s description should describe the main idea of your product. You can make this part more engaging by highlighting the problem that your app solves. These sentences shouldn't exceed a combined total of 225 characters.
  2. Mention special achievements. Let your future users know if your app has been featured on TechCrunch, has won an award, or if Johnny Depp is talking about it.
  3. The body of the description can include 2-3 paragraphs where you describe characteristics and details.
  4. List several main functions with concise descriptions.
  5. Talk about 'What’s new?' Inform customers about bug fixes, color changes in the side menu, or the addition of new features. This should be the final component of your app description.

App screenshots

The first screenshot is the most important. It describes what your app does. If you add text to your screenshots, use verbs. Verbs push people to take action better than any other part of speech. Verbs are your friends.

General recommendations for composing a product definition:

- be clear and concise when explaining how your app works and why people need it.
- use keywords both in the app’s name and in its description.
- write directly to your user (using you, as opposed to using people, or they, or users).
- avoid technical details and ambiguous sentences.

Now, as the brief part is over, we can dive deeper into how to create the ultimate app definition.

What is your app name? Why do people need it? Let’s find out the answers.

Why your app name is essential for future users

There is usually no connection between an app's name and what it does. As I’m checking the Best New Apps on the App Store, I am passing by CHOMP, Flowstate, Sloth – I have no idea what these names mean. Help your future users find your app as one they would want to download.

How does an app name attract users?

To make an app’s functionality clear for users – and to improve app visibility – you need to blend an app’s purpose into its name. Your app’s purpose should be boiled down to a keyword that people will use to search for a specific solution on the App Store or Google Play Store. The principle is the same for Google web search. 

If you type ‘app development company’ into Google’s search box, you will find Yalantis. This is because our full name is Yalantis: iOS and Android app development company.

If you type ‘travel app’, you will find TripIt (TripIt Travel Organizer — Free), TripAdvisor (TripAdvisor Hotels Flights Restaurants), TripCase (TripCase — Travel Organizer), and other travel apps.

Let’s take our app My Day as an example. Its full name on both app stores is My Day — Countdown Timer. ‘Countdown timer’ and ‘countdown app’ are keywords.

Looking at the title ‘Flipboard: Your Social News Magazine’, we know exactly why we need Flipboard. What’s more, there are three keywords right away: news, social, and magazine.

A few examples of great app titles

Brilliant Move, one of our projects, uses the following name in the Google Play: Brilliant Move — On-Demand Delivery. This name lets people know what Brilliant Move does. Check out our Brilliant Move case study here.

Here are three more examples of apps that highlight their unique features in their title:

Shazam — Discover Music, Video & Lyrics
Magisto Video Editor — Movie & Music Slideshow Maker
Jet Journal: Explore & Share — Travel Blog & Trip Planner
By the way, Jet Journal is a social travel app built by Yalantis. Read the Jet Journal case study here.

You can have as many as 25 characters in the app name. If there are more characters, people won’t see them in the search.

How to write an app description

Follow these rules to write an app description that sells:

SLAP (Stop. Look. Act. Purchase). Capture the attention of your potential customers by using simple sentences. People are more likely to download an app if they understand exactly how it can make their lives better.

KISS (Keep it simple stupid). Get rid of all words that don’t carry any meaning. Don’t use cliche, buzzwords, and jargon. Use real words.

WIIFM (What’s in it for me?). What will people get, learn, and feel once they download your app? What’s your app’s value proposition?

You should explain how to use your product from a user’s point of view as if you were a user yourself. Writing a great app description is easy. You need to answer only one question:

What features does your app offer?

Typical mobile apps have a lot of different functions from registration to terms and conditions. But we don’t need to talk about all these functions in the app description. It’s enough to point out just a few core features and one killer feature. The killer feature is your value proposition. It can also be your competitive advantage or positioning of your product on the market.

If you position your app as the best notebook, for example, then you should focus on taking notes. If your app can find cheap tours, you should highlight this in your app description.

Talk about one specific use case rather than every single function that your app offers.

The main feature of our app My Day is a countdown clock with reminders. Other functions include wallpapers, holidays, widgets, color and style settings, and more. We position My Day as a beautiful product and this is its value proposition.

What does an app description include?

We can divide an app description into five parts:

  1. 255 characters
  2. Review and awards
  3. 2-3 paragraphs of the body text
  4. A list of features
  5. What’s new?

The first 255 characters that appear in the App Store listing are the most important — this is what users can read without having to tap 'more.'

If this text isn’t catchy enough, a user won’t bother reading further. They might not download your app in the first place. So, use 255 characters to describe your unique value proposition.

1. How to make the most of the first 255 characters in the listing?

Start with a concise, attention-grabbing sentence that explains why your app is cool and why people need it. Describe a problem and say how your app can solve it. If there doesn’t seem to be any problem for your app to solve, create one.

Sometimes a problem that a product can solve is obvious. For example, with a fitness app, you can do exercises wherever you are. A dating app increases your chances to find love. A social app for movies offers you an opportunity to discuss art house with those who care.

Even if your app belongs to the entertainment category, you can describe it as a solution to a problem. Let’s take Vine, a social app for funny videos.

How Vine persuades users that it will solve their problem 

Vine is the entertainment network where videos and personalities get really big, really fast. Vine’s creators emphasize that you and your video will quickly become popular. This is important for the target audience of Vine. Then we see the following:  

‘Watch videos that create trends, influence culture and make you laugh. Discover stories, characters and remixes you can’t find anywhere else. Be the first to hear incredible new artists and songs.’

They sold the app to me here. I can create trends, laugh, and watch ‘stories you can’t find anywhere else.’ All this makes me think that Vine is a unique solution.

‘Watch videos, discover stories, new artists and songs’ are all keywords that properly fit into the context.

Sometimes, a problem that your app can solve isn’t obvious. For example, Uber and Instacart are products created for comfort. When they were just launched, people didn’t even know they had a problem that these guys wanted to solve. Today, though, some of us can’t even imagine getting around the city without Uber.

What about other examples except for Vine?

Rewind — Timetracking:

‘The best time tracking solution is the one you don’t even have to think about. Rewind automatically tracks your time based on your location. You just have to set up your important places and you’re done.’

Let’s see:

  1. ‘Tracks time based on your location’ — this is the killer feature.
  2. ‘The best time tracking solution is the one you don’t even have to think about.’ – this is a problem that the app solves.
  3. ‘You just have to set up your important places and you’re done.’ — this is how to use the app.

They didn’t say much, did they? But we know why we need the Rewind app. Go download it if you wish, or stay here to learn more.

2. Review and awards

If your product received a review from a respected source, you should put a quote from this review into your app description.

Examples of reviews

- Quip — Docs, Chat, Spreadsheets: ** Featured in MIT Technology Review’s 10 Breakthrough Technologies 2014 **
- Wish — Shopping made fun: 'Love, love this app. It’s a fun app that u can wish on things u love and want. Highly recommend it to frndz & fmly,' — Olivia Austin.
- 'A must-have for moms!' — TechCrunch

Examples of awards

AP Mobile is the award-winning app from The Associated Press, the definitive news source relied upon by thousands of newspapers, broadcasters, and digital news providers worldwide.

Musixmatch Lyrics Finder: Musixmatch is the world’s largest lyrics catalog, that lets you enjoy diverse music with synced lyrics. Out of 155 countries, it was selected for the Editor’s Choice on the App Store and was also chosen as an App Of The Year in 2013.

If your app won an award, make sure to explain why:

- news source relied upon by thousands of newspapers
- the world’s largest lyrics catalog

If you have neither awards nor reviews from a respected source, you can include a review from a regular user. But in this case, your app should have a specific use case: medicine, for example. Keep in mind that awards and reviews provide social proof that your app is hot stuff.

3. Body paragraph

App descriptions are like news articles: the main news comes first, details follow. The shorter the paragraphs in the app description, the easier they are for people to understand.

The-Wunderlist-App

By now we've already talked about the most important features that your app offers:

- ‘Wunderlist helps millions of people around the world capture their ideas, things to do and places to see. (Wunderlist: To-Do List & Tasks)’

Now is the time to dive deeper into details and characteristics:

- ‘Whether you’re sharing a grocery list with a loved one, working on a project, or planning a vacation, Wunderlist makes it easy to share your lists and collaborate with everyone in your life. Wunderlist instantly syncs between your phone, tablet, and computer, so you can access your lists from anywhere.’

From this paragraph, I learned what exactly I can add to my lists and how I can use them. Being specific and personable allows you to connect with your customers.

The body paragraph is an excellent place for keywords (but never repeat what you have already said).

4. A list of functions

It’s advisable to have 3-7 functions in the list. They all should have a name and a short description. Features can come with a subheading followed by a sentence or two:

-VSCO Journal™
- ‘Publish original content to your Journal and share with the creative community. Find inspiration on the VSCO Journal, a publication highlighting creatives from around the globe.’

One more example

One more example is NYC Apartments and Real Estate by StreetEasy — an app that we developed for Zillow. The main function of this app is a property search. That’s why ‘search’ is the most used word in the app description for the App Store. Besides ‘search’, StreetEasy app description lists the following features:

- ability to view, save and share for-sale and rental listings;
- email and call agents directly from the app; 
- tap into the database for all kinds of market- and property-level facts and history

Rules to keep in mind when listing features

  1. Don’t make feature descriptions too long.
  2. Place the two most important features at the beginning of the list and the third most important at the end of it.
  3. Nobody reads anything here.
  4. Nobody reads anything here.
  5. Every new function should start with a new word. All these words should belong to one part of speech (verbs, adjectives, nouns).
  6. The third most important function.

Then, you can talk about how your app makes money and why people should pay for it. But we'd recommend that you let people discover premium content after they have already downloaded your app.

The-StreetEasy-App

5. What’s new?

Everything that you fixed or added to the app in the latest version(s) goes into the very last part of the app description. The easiest way to describe how you improved the user experience is by using verbs and gerunds. But you can use whatever words feel right to you.

For example:

- Now supporting iOS 9
- Likes: See who liked your post
- Now you can book up to 4 hotels at once on the app
- Fixed a bug affecting some iPhone 6 and 6 Plus readers

What you should and what you mustn’t do in the app description

Should

- Briefly describe the app’s value proposition.
- Speak to the target audience with the phrase 'ideal for.'
- Convince: 'Free forever!'
- Increase credibility with a phrase such as 'From the creators of...'

Mustn’t

- Overuse keywords in the app description: too many keywords with a loose connection to the content don't make any sense and spoil an app’s ranking.
- Make grammar mistakes and typos.
- Speak the technical language.
- Write something like this: our product was made in New York by Tom Smith, an iOS developer.
- Lie. This is how you get bad reviews.
- Use confusing and abstract sentences.
- Exaggerate, use buzzwords, jargon, and cliche. Cross out revolutionize, game-changing, disruptive, value-added, impactful, cutting-edge, best-of-breed, and go-to and substitute them with real words.

How to write a description for screenshots?

Write a brief, clear, and informative description for screenshots. They need to describe the main functions of the app and talk about exact use cases. The first screenshot is the most important. It should describe the app’s value proposition. There should be a total of five screenshots. 

BuzzFeed News:

  1. We make the news easy to follow.
  2. We make the news easy to understand.
  3. We make the news easy to manage.
  4. We make the news easy to share.
  5. The most interesting and exciting stories from around the web.

BuzzFeed News gives people an easy tool for following the news. This is exactly what they say on their screenshots. Making news 'easy' is the app’s competitive advantage.

The-BuzzFeed-App

Another app whose screenshots are amazing is Spark:

  1. Discuss email privately.
  2. Schedule emails.
  3. Connect all accounts.
  4. Create email together.
  5. Create links to email.

The-Spark-App

Some screenshots are so self-explanatory that they don’t need a description at all. Take a look at Drawnimal to see what I mean.

How to find keywords

We suggest you use:

- your imagination
- Google Trends
- Google AdWords Keyword Planner

Don’t stuff your app title with keywords, but do keep in mind that an app’s name serves as a primary field for indexing by Apple. The Google Play Store counts keywords in both the title and description.

It doesn't matter what platform you launch an app for. Keywords should appear in the app description and in its title. This is because people also look for apps in Google web search or in other search engines as well.
