Free tools for indie devs.
Little utilities we built while preparing our own store listings. They run in your browser, need no sign-up and never upload anything.
Store listing counter
Write your title and descriptions here and see exactly how close you are to the Google Play and App Store limits.
Icon mask preview
Drop in your app icon and see it under the masks Android launchers use, and on a home screen next to other apps.
