Depthlog AI

Your dive coach that never does the math wrong

Depthlog AI reads your real journey and answers with the real tables, never from memory. Every NDL, RNT, MOD, SAC or CNS figure is computed by Depthlog, then shown to you with the trace of the tool that produced it. Supporter includes 15 free credits to try it; after that, buy credits only when you need them.

  • Answers computed from the real tables, never invented
  • Reads your whole journey: stats, records and trends
  • Log a dive from a photo or a pasted file, in seconds
  • Conversational stats like your average SAC on a trip

Every figure is shown with the trace of the tool that produced it. The AI is a coach, not a replacement for your training, your computer or your instructor.

A note from Matteo Beltrame

I built Depthlog because my own dives were scattered across paper and dated apps. I want the free logbook to stay free and complete, and I want the paid part to be worth it on its own: beautiful exports, real trip recaps and an AI coach that respects your safety. If that sounds right, thank you for supporting it.

An innovative and intuitive application with constant updates. Really love the global map: as I log new dives I can visually identify all my diving spots around the world.

A fast way to log the info I want and have it accessible anywhere with global statistics and metrics. Plus, no more photo search on the phone gallery for diving certifications!

Used to guess my SAC, so repetitive dives were a shot in the dark. Now Depthlog keeps my stats in one place and I know what I have before I get back in. Logging here beats pairing my Bluetooth computer.

As a beginner, this app has been a game changer. Logging is so quick that I actually keep up with it, and seeing my SAC and depth improve has done wonders for my confidence underwater. It is officially part of my dive gear now.
