Rewind allows you to passively record your surroundings. This app continuously runs in the background and records everything your phone hears, allowing you to save recent recording when you hear something you would like to keep. 🎙 You can record from within the app, by toggling the app notification (you can disable this in the settings), or by using the app widget on your launcher.
This app is useful for:
✅Recording moments you would have otherwise missed
✅Surveillance and recording harassment
✅Recording notes and memos
Did you wish you could rewind time? Capture those moments before you miss them. Get Rewind now!
Until you press save, the recording is held on the RAM (because a recording of the last X minutes needs to be continuously trimmed and that would be fairly inefficient on the device storage).
This app requires the Phone permission (READ_PHONE_STATE) so Rewind can stop/resume recordings during calls, so your call recording apps can work properly. You can disable this functionality in the settings.
