Localize your app and its store listing in one place

Launchglot translates in-app strings with AI while keeping placeholders and plurals intact, and rewrites App Store / Google Play listings for each market — from one shared app description and glossary.

One shared context

Write your app description, tone and glossary once. The same context drives both in-app string translation and store listing copy.

Format-safe translation

Placeholders (%s, %1$@, {name}, {{count}}), HTML tags and plurals are protected and validated. Failures are flagged for review, never silently exported.

Your file formats

Upload Android strings.xml, iOS .strings, Xcode .xcstrings or JSON (flat or nested). Export back to the original format.

Review editor

Filter, search and edit translations side by side with live validation and version history.

Store listing editor

Edit App Store and Google Play listing fields per locale with live character (and UTF-8 byte) limits.

Store publishing (coming soon)

Connect Google Play and App Store Connect to push localized listings after a diff preview and confirmation.

How it works

Create an app and describe it: audience, tone, glossary.
Upload your string files and pick target languages.
Translate with AI, review validation and QA warnings, then export in the original format.
Localize store listings per market with live length limits.

Launchglot is in early access. Direct publishing to App Store Connect and Google Play is coming soon; until then, copy or export your localized listings.
