Universal Undo

The app runs a lightweight on‑device service that continuously records recent text states from any active input field on Android. When a user accidentally clears a draft, switches apps, or otherwise loses the last version of their typing, the service can restore the text via shake gestures, floating controls, or a timeline view, without sending any data off the device.

It is aimed at people who frequently compose messages, notes, email drafts, or fill long forms on Android and need a quick way to retrieve lost content without relying on cloud backup. The design includes a blacklist feature that lets users exclude specific applications from being tracked, preserving privacy for sensitive inputs.

What sets it apart is its focus on real‑time, local recovery that mimics a Ctrl+Z undo experience across arbitrary apps, packaged in an under‑3 MB installation with a simple setup process and no external account requirements.
