An app store description generator writes your listing's text fields around the keywords you want to rank for, inside each store's limits. ReachFront's ASO Generator produces, for iOS, a 30-character title, a 30-character subtitle, a 100-character keyword field that repeats no word already in your title or subtitle, up to 170 characters of promotional text and a full description; and for Google Play, a title, an 80-character short description and a full description up to 4,000 characters. Every field is trimmed to its limit before you see it, and you can copy fields one by one or download them all.
From a few facts to a full listing
Which fields actually rank your app
Your listing does two jobs: it tells store search which queries to show you for, and it persuades a person to install. The two stores read different fields for the first job, which is why one listing pasted into both rarely works.
On the App Store, search reads your title, subtitle and the hidden 100-character keyword field, not your description. Words already in the title or subtitle are wasted in the keyword field. On Google Play there is no keyword field: search reads your title, 80-character short description and full description.
The generator writes each store's version separately. On iOS it builds the keyword field in code so it never repeats a title or subtitle word and never runs over 100 characters, and it adds promotional text, the 170 characters you can change without a new app release.
A generated iOS listing, field by field
What the iOS output looks like for a habit tracker, with each field's limit.
| Field | Limit | Example output |
|---|---|---|
| Title | 30 | Habitly: Habit Tracker |
| Subtitle | 30 | Small daily streaks that stick |
| Keyword field | 100 | routine,goals,planner,reminder,motivation,journal,self care,mood,focus,checklist |
| Promotional text | 170 | New: gentle reminders that skip the guilt. Miss a day and your streak bends instead of breaking. |
| Description | 4,000 | Opens with the benefit, then features in short sections (shortened here). |
Writing a listing by hand vs. with the generator
| By hand | With the generator | |
|---|---|---|
| Character limits | Count characters in every field and trim until it fits. | Every field arrives inside its limit, trimmed at a clean boundary. |
| iOS keyword field | Juggle 100 characters and remember not to repeat title words. | Built in code with no repeats of your title or subtitle words. |
| Both stores | Write one listing and paste it into both. | A separate version for the App Store and for Google Play. |
| Promotional text | Often left empty because it is one more thing to write. | Written with the rest of the listing, ready to paste. |
| Time to a draft | An afternoon of drafting and second-guessing. | A full draft in about a minute, then you edit. |

App Store Description Generator, answered
Which fields does it write?
For iOS: title (30 characters), subtitle (30), keyword field (100), promotional text (170) and full description (4,000). For Google Play: title (30), short description (80) and full description (4,000). You also get a short list of the target keywords it wrote around.
Does it work for both the App Store and Google Play?
Yes. Choose iOS, Android or both, and each store gets its own version written for the fields that store indexes.
What do I need to give it?
Your app's name, category and main features are the essentials. Audience, tone, a primary keyword, secondary keywords, phrases to keep in your title and your current store URL all make the result sharper.
Will the copy help me rank?
It puts your keywords in the fields each store reads for search and fills the iOS keyword field without waste, which is the part of ranking your listing controls. Ratings, downloads and competition still matter, so pair it with Keyword Research to pick winnable keywords.
Does it write in other languages or write What's New notes?
Not yet. Listings are written in English, and release notes (What's New) are not part of the output.
Can I use it before my app is published?
Yes. A store URL is optional; describe the app's features and audience and it writes your first listing from that.
