Fins Tribe App
A community of divers created to leave paper behind.
Every dive used to start with forms, signatures and printed sheets. Scuba Sign (the paperless registration system used by dive centers) and Fins Tribe (the community app that runs on contributions, made by divers, for divers) were born together to change that.
With Scuba Sign you register and sign once, on your phone, with full legal validity and nothing to print. With Fins Tribe, that same community identifies marine life, learns from the encyclopedia and helps protect the ocean.
Every sheet we don't print is a small gift to the sea: less waste, less pollution, a healthier ocean for every dive that comes next.
The app will keep growing. New tools are already on our list, and they will arrive as the community joins and supports the project: the more of us there are, the more we can build together.
Thank you for being part of the tribe.

Games zone coming soon!
We're working to bring an idea we love to life: learning by playing.
Very soon, in this section you'll be able to challenge your buddies with trivia, memory games and much more.
As an instructor, my mission is to keep teaching, and my dream is for the whole community to keep growing in knowledge.
Thank you for supporting and spreading the Scuba Sign Paperless Diving and Fins Tribe Community project.
See you underwater!
