Focused, free Android apps. No accounts, no sign-up, and your data stays on your phone wherever it can.
Open the app and use it. Nothing to sign up for, nothing to log in to.
Your tasks, bookmarks and history are stored on your phone, not on a server.
Most apps are free and supported by Google AdMob ads; Anime Studio is a one-time unlock with no ads at all. Each app's privacy policy spells out what that means.
