iOS: Sometimes you just need to quickly get down an idea without fumbling around with buttons. Say&Go is a simple app that, once launched, instantly starts recording a very short voice memo.
When you launch Say&Go it immediately starts recording a seven second voice memo (you can up this to 10 seconds if you want). When the time's up, the recording stops and it can be automatically uploaded to Dropbox. This makes recording a short idea quickly surprisingly easy.
