About this app

Join & Dive is a place for divers, instructors, and diving organizations. Discover new activities, organize your own dives, events, and courses, calculate gas with dive calculators, and stay connected with participants and the community.
DISCOVER ACTIVITIES
Browse dives, events, and courses on a list or map. Check dates, locations, available spots, requirements, and organizer information.
DIVE CALCULATORS
Select the best nitrox or trimix for your planned depth, or check the gas in your tank. Calculate your rock bottom—minimum gas supply and the starting point of your ascent—using your own gas consumption and settings. The calculators also work offline, and you can share the results with your buddy.
ORGANIZE AND MANAGE
Publish your own activities as a diver or on behalf of your organization. Manage registration, participants, required documents, and participant materials. STAY CONNECTED
Use private messaging and discussions. Receive information about important changes and choose which notifications you want to receive.
BUILD A DIVING COMMUNITY
Add friends and diving partners. Develop your organization's profile, build your own community, and manage a team of representatives.
MANAGE YOUR DIVING PROFILE
Add certifications and equipment, store related documents, monitor service dates, and decide which information will be publicly visible.

Join & Dive provides social and organizational tools. It does not organize user-provided activities and does not replace training, required qualifications, or independent assessment of diving conditions and risks. Diving calculators are for guidance and education purposes only – they do not replace a dive computer or a dive plan prepared in accordance with completed training.
