How long can App Store and Play release notes be?

The iOS App Store allows up to 4000 characters in the What's New field, while Google Play limits the What's new section to 500 characters. This builder shows a live count for each so you stay within both.

Why are the two stores formatted differently?

The App Store renders the text with more breathing room and supports a longer note, so it gets bullets and a thank-you line. Google Play's field is short and plain, so the Android version is compact and leads with the version number.

Should I mention every change?

No. Highlight the few changes users will actually notice — the headline feature and the most impactful fixes. Routine internal changes can be summarized as 'bug fixes and performance improvements'.

Does tone matter in release notes?

Yes. A friendly or playful tone fits consumer apps and can lift ratings, while a professional tone suits business and finance apps. The builder rewrites the intro line to match the tone you select.

Can I ask for a rating in the notes?

A short, polite rating nudge in App Store notes is common and effective, which is why the friendly template ends with one. Keep it brief and never make it feel like begging.

One update, both stores, no rewriting

Shipping a mobile update means writing release notes twice — once for the App Store and once for Google Play, each with different length limits and conventions. This builder takes a single set of features and fixes and produces a properly formatted note for each store, with live character counts so you never get rejected for overflowing the field.

How it works

You enter the app name, version, and tone, write a short What’s New headline, and list new features and bug fixes one per line. The builder constructs two outputs from the same input. The iOS version uses a tone-matched intro, bullet-pointed features, a separate bug-fixes section, and a polite rating nudge, fitting the App Store’s generous 4000-character field. The Android version is compact and plain — leading with the version number — to fit Google Play’s 500-character limit, and the tool warns you when you exceed it. Each store gets a copy button so you paste the right text into the right console.

Tips and example

Lead with the single change users care about most, for example Faster exports and a fresh dark mode, not a laundry list.
Keep Google Play notes tight; if the counter goes red, cut the least important fix line.
Match tone to category — professional for a banking app, playful for a game.
Reuse the same notes as your in-app “What’s New” screen so messaging stays consistent.
