Heard: an app that records what you heard 5 minutes ago

Awesome! Even with kids would think we want to sometimes forget what was said.

Two technical problems though:

  • This app is running in the background recording audio. Isn’t this going to consume a lot of battery? I barely get 5 hours of active use as it is.
  • A microphone is useless if it is not pointed at the sound source (noise reduction etc). You would have to have the phone plugged to a microphone perpetually pinned to your shirt. Sounds inconvenient.

Now for Google Glass applications, I can see plenty of uses, and hopefully not just for audio. In a few years the battery problem should be resolved, and Google Glass is pointed at the source all the time by design.
