I think an ideal system would include voice notes. The problem is, I would really like it if the voice notes were geotagged and timestamped AND really easy to record. I think a smartphone app is to cumbersome. It should be a single physical button, just for that purpose. What I really would like is a minimal device with a microphone and a button, that stores the notes in my phone. I have not figured out how yet.
