RubberHose Recorder is an iPhone app that lets you record audio with continuous backup.
Audio files are not only stored locally but a copy is also stored on a server for a week. The server copy cannot be deleted before that time. This allows you to keep a record of situations where you may be asked (politely or not so politely) to delete any recordings you have made.
Usage:
1) Start the app.
2) Optionally enter an email adress.
Uses the Opus-codec and icons from Icons8.com
