Subsurface-mobile allows you to access your dive log on your tablet or phone, edit the data and even download new dive information from many Bluetooth LE enabled dive computers. Using a free Subsurface Cloud Storage account you can synchronize your dive data with the Subsurface desktop application (while significantly increasing the usefulness, the cloud account is not required to use Subsurface-mobile). To get support from the developers, please use the in-app menu entry "Ask for support" Please check out the Subsurface-mobile user manual: https://subsurface-divelog.org/documentation/subsurface-mobile-v3-user-manual (also available from within the app) Subsurface-mobile is free and open source.

Whether you're a seasoned diver or just beginning your journey beneath the waves, our app is designed to enhance your diving experience and connect you with a community of like-minded ocean lovers. Dive in with us and explore the wonders of the sea, one dive at a time. WHO WE ARE We at Digidive are passionate scuba divers who find joy in exploring the underwater world, whether it's shallow diving with vibrant fish or delving into the depths of wrecks and caves. Our adventures have taken us to stunning locations, and our love for the ocean has only grown with each dive. OUR GOAL Recognizing the need for a comprehensive and user-friendly dive log, we set out to create an app that caters to all ocean enthusiasts—scuba divers, free divers, and snorkelers alike. Traditional paper-based dive logs have their limitations; they are difficult to search and lack the interactive features modern technology can provide. DIGIDIVE APP Our app allows you to seamlessly track your dives, capturing every detail of your underwater experiences. Log your dive sites, conditions, marine life encounters, and more, all in one easily accessible place. Beyond just recording your past adventures, our app also features a "Wish List" function, enabling you to set and keep track of your dream destinations. Our FREE trial provides basic access to all features. Then, if you like what you see, you can upgrade to see your full dive log history and to upload as many dive photos and certifications as you like.
