I use Otter pretty religiously to record all work meetings that I participate in. That is probably overkill, but it is great to be able to go back and find details about something I didn't take notes on or wanted to review.

I work with a geographically distributed team and it doesn't do an amazing job with English in various accents — I've noticed Google Recorder on Android is better in this regard — but it's good enough.

Nice product.
