Thanks for the constructive feedback, appreciate it a lot, really! I developed many mobile apps in my career and I am surely planning to bring it to mobile. However, I want to make sure there is enough "interest" before taking the big leap. Also, it is always possible to add dives to the app later on, maybe with internet connection (provided a computer or something to store them).

As for the lifetime price, you are mostly correct. Yet I want to experiment with this payment model since I had experiences that proved me that a generic customer is actually more keen on purchasing 10 dollars or more one time rather than 1 dollar recurring.

As an update, I am already collaborating with some communities with the affiliate program, I am very happy for that. Maybe the market is really demanding for something more and it might be a good opportunity, we'll see!
