chirp.io (iOS, Android)
Birdsong is priceless, but robotic birdsong is free. Chirp allows you to share pictures, notes and web addresses as sounds. It's like a tweet, but only reaches those within earshot. You can get information quickly to everyone in a meeting without having to pair devices by Bluetooth or open emails, and it even works in busy pubs. The app does need to be open to receive a chirp, however, and it may not be right for those with sensitive ears. Rating 2/3

It's fully waterproof and can easily be worn as a watch or pendant. It doesn't have a display, though, so you'll need to sync wirelessly with the app to see your progress.
