Auto Record Moments

This app continuously records audio to a ring-buffer of fixed size in a battery- and memory-efficient manner. When the save button is press, a configurable amount of time in the past is processed and has all non-speech filtered away before being saved to device. Quality is also configurable. The save button can easily be accessed from the persistent notification, for example from the lock screen.

Useful for generally capturing moments you usually would realize too late would be good to save. Can be used for saving memories, evidence, couples therapy, speech logging etc.
