Storeboard/For cross-platform developers
Store listings for Flutter & React Native developers
You picked cross-platform so you'd write the app once. Nobody mentioned that you still have to write the store page twice — and that the two stores disagree about almost everything that matters.
Google Play indexes your description. The App Store does not. That one fact means the copy that ranks you on Play is dead weight on the App Store, and vice versa. Reusing a listing across both stores wastes the mechanics of both.
What's actually different
| App Store | Google Play | |
|---|---|---|
| Description indexed? | No | Yes |
| Hidden keyword field | Yes — 100 chars | None |
| Short text field | Subtitle, 30 chars | Short description, 80 chars |
| App name | 30 chars | 30 chars |
| Feature graphic | None | Required, 1024 × 500 |
| Screenshots | Per device family, exact sizes | More flexible sizing |
| Changing keywords | Needs a new version | Edit the description any time |
So the same "one codebase" instinct that served you well in the app fails completely at the store. The positioning transfers. The captions mostly transfer. The search strategy does not.
How to write for each store
App Store: dense and hidden
You have about 160 indexed characters — name, subtitle, keyword field — and Apple counts each word once across all three. So the game is density and zero overlap: no repeated words, no phrases (Apple combines words itself), no spaces after commas. The description is purely a conversion asset; write it for humans.

Google Play: natural and long
Your long description is the searchable surface, so terms need to appear in readable prose. Stuffing is penalised; natural repetition is rewarded. It's much closer to classic web SEO — and it's editable without shipping a build, which makes iteration cheap in a way the App Store never is.
On the App Store, keywords are locked to your release cadence — get them wrong and you're waiting for the next version. On Play, you can fix them this afternoon. Plan the App Store field more carefully, precisely because you can't hotfix it.
Screenshots: shared design, separate exports
The good news is your design is portable — the same captions, the same visual language, the same story order. What isn't portable is the export. Apple validates dimensions strictly per display type, and an image that's perfect for one bucket is rejected in another. Play is more forgiving on sizing but wants a feature graphic that has no Apple equivalent at all.
The workable model: design once, then export per store rather than trying to make one set satisfy both. Every App Store dimension →
Localization compounds across both
This is where cross-platform gets genuinely painful. Each store localizes separately, so your matrix is stores × device families × languages. Ten languages across both stores is twenty listings to keep in sync, and they drift the moment you update one.
Worth knowing: App Store localizations each carry their own keyword field, so English (US/UK/AU/CA) are four separate ranking opportunities. Play has no equivalent trick — you get one description per language. More on the App Store side →
Get the App Store half right
Storeboard handles the App Store side end-to-end — design, per-country keyword research, localized metadata and pixel-exact export — on your Mac, nothing uploaded.

Can I reuse my Play Store screenshots on the App Store?
Not as files — the dimensions differ and Apple validates them per display type. The design and captions carry over fine; the exports have to be produced per store.
Which store should I optimize first?
Whichever earns more for you, which for most paid or subscription apps is the App Store. But note the asymmetry: Play mistakes are cheap to fix, App Store keyword mistakes wait for your next release. That argues for spending your careful thinking on Apple's fields.
Does my Flutter or React Native stack affect ASO?
Not directly — neither store ranks you on framework. It matters indirectly: shipping to both stores doubles the listing work, and that's usually what gets skipped.
Do I need separate keyword research per store?
Per store and per country. The intent overlaps, but the mechanics differ so much that the output is different — a dense comma-separated field for Apple, natural prose for Play.
