Diving Standard on Android includes seven illustrated courses: snorkelling, freediving fundamentals, scuba basics, a full Open Water theory course with knowledge reviews and a final exam, Nitrox, Certified Freediver Level 1 and Mermaid theory. Most are free, and some unlock when you invite a buddy. They teach the theory. To get certified you still need practical training with a qualified instructor.

Theory is the part of learning to dive you can do on the sofa, on the bus or the night before your trip. Do it first and you arrive confident, ask better questions, and spend more of your course actually in the water.

The courses

CourseWhat it's for
SnorkellingStarting out: a mask that seals, fins that fit, and being comfortable in calm water
Freediving FundamentalsThe basics of breath-hold and relaxation, and why the urge to breathe arrives long before any real limit
Scuba BasicsAn introduction to the underwater world and how scuba works
Open Water theoryA full theory course with knowledge reviews and a final exam, from how you see underwater to planning a dive
NitroxEnriched air: why a richer mix extends your bottom time and lowers your maximum depth
Certified Freediver Level 1The theory for an entry-level freediving certification, including breathe-up and safe holds
Mermaid theoryThe theory behind the Certified Mermaid course, a calm breath-hold sport

What makes them different

The courses teach theory. To be certified you still need practical training in confined and open water with a qualified instructor from an agency such as PADI or SSI. Our guides on how to get scuba certified and how much certification costs cover the next step.

Where to start

  1. Not sure it's for you?: Start with Snorkelling or Scuba Basics, and read snorkelling vs scuba diving.
  2. Ready to get certified?: Do the Open Water theory first, then book your practical course with a dive centre.
  3. Drawn to breath-hold?: Try Freediving Fundamentals and read how to train for freediving.
  4. Already certified?: Add Nitrox, and read what is nitrox.
