Petral compatible
The app allows you to put as much detail about the dive as you want. If you want you can include a photo, gps, coordinates, dive site name, depth, temperature , etc It syncs easily with the petral. If you sync with the petral all your information comes across and even includes a graph of the dive.
You can have the dive master electronically sign your log. The only problem I have had is with syncing between iPad and iPhone. I contacted customer support and got a long and detailed response. Now the sync works fine.
For the price of a manual log book how can you not try it!
