Although a good voice recorder is an invaluable gadget for anyone who takes a lot of notes or attends a lot of meetings and interviews, the reality is that not everyone knows how to use one or may not know it's necessary until it's too late. Take, for example, our office: we have a small pool of voice recorders that we share, but sometimes they go missing or run out of juice, so inevitably, a lot of emails go around about who had one last. Thankfully, there's an app to replace your battery-powered recorder that will save you time and stress.
I use iProRecorder on my iPhone for all my interview and note-taking needs, since it's easy to not only record at different speeds and decibels but to email the audio to yourself. That last point is key for anyone who wants to back up recordings for later transcription. It stores hours of audio and allows you to slow down or speed up playback for easy review (unlike the standard-issue voice recorder on your 3GS). Plus, you don't have to fish around for another gadget in your bag — it's on your phone! iProRecorder will cost you $3, but to us Sugar Gals who are busy trying to get the scoop from the source, it's totally worth it.
