Have you ever wished that you could record something that already happened? Your kid’s first words. That perfectly timed comeback. The email address your boss told you to have those important documents sent to within the next 10 minutes. If only there was a way to record the important bits of your life, without having to record all of it. That’s the idea behind Heard, a new app for iOS. Heard constantly records the audio around you into an ephemeral, self-destructing buffer, saving only those fleeting moments that you deem worthy. Once you open Heard, it immediately begins recording everything within earshot of the iPhone’s microphone. Rather than dumping all of that audio into one incredibly boring and incredibly long file, though, Heard records into a constantly rotating buffer. If something happens that you just have to save, you pop into the app and tap a single button — boom, it’s saved.
