πŸ‘‹ Welcome to r/PelagicApp - the community for Pelagic dive log & computer

Hey everyone,

I'm Phil, the developer behind Pelagic. Glad you found us.

I started building Pelagic for three reasons:

  1. Every dive log app is either ugly, clunky, or abandoned. I wanted something that actually looks good and is a pleasure to use.

  2. Manufacturer apps are proprietary dead ends. Your dive data should be yours, not locked into one ecosystem.

  3. Dive computers are expensive. If you already own an Apple Watch Ultra, you have a wrist-mounted computer with a depth-certified sensor. It should be able to run a proper decompression algorithm. It can β€” and it shouldn't cost you $10 a month to do it.
