Ratings and reviews

way better than the PADI app, I dont see why everyone is in an uproar over PADI international training is the way to go!

Could use tables or calculator to help with nitrox calculations to double check dive computer. Awards/rewards only on browser not in app. Direct integration with dive computers would be fantastic.

Easy to navigate and use. They found my 3 TDI certifications from 2001 and posted them for me. It was unbelievable & cherished memories for me diving with the legendary Hal Watts at his forty fathoms location in Ocala, Florida, where I was certified.
