Fossify Voice Recorder
★★★★☆
A simple mono recording app where the audio stays on your phone. No ads, no subscriptions, no remotely-generated transcripts, just basic recording.
I’ve found it useful for making quick voice notes I can come back to later, and for recording audio observations for iNaturalist when I can hear, but can’t see noisy animals. It should work for longer recordings too: there’s no time limit as far as I can tell.
There’s a setting to start recording as soon as you launch the app, and a widget in case you want one-click recording sometimes, and some simple options for choosing a bitrate and file format (M4A, MP3, or Ogg).
