Well, as a 46 year old diver, who’s has been diving since 1990, a large percentage of my dives are entered is paper logs. Although I use a computer on some of my more recent dives, I still like to go old school and do without. I purchased this app thinking I’d be able to log the hundreds of dives I made before the age of dive computers, but it would appear this is not an option. But nowhere did I see that this was the case before spending my money. This said, I am not impressed.
