About this app

Bubble Deco is a professional-grade scuba diving decompression planner built on the Bühlmann ZHL-16C algorithm with gradient factors -- the same science used by technical divers worldwide.
Plan with confidence

Enter your depth, bottom time, gas mixes and gradient factors. Bubble Deco calculates your decompression stops in real time, accounting for all 16 tissue compartments continuously throughout the dive.
Repetitive diving done properly

Plan a whole trip across multiple days. Bubble Deco threads your tissue loading continuously from one dive to the next -- including surface intervals -- so your decompression is calculated for the dive you're actually on, not in isolation.
Diver profiles

Set up profiles for yourself and your buddies, each with their own gas consumption rates, gradient factors, gas mixes and cylinder. Pick a diver and everything fills in automatically.
Altitude diving

Heading to a high-altitude lake? Set your site elevation and Bubble Deco adjusts surface pressure automatically using the barometric formula.
Share your plan

Generate a shareable dive plan card -- depth, deco stops, gases and run time -- ready for WhatsApp, your dive club group chat or your camera roll.
Export your log

Export in UDDF, the open standard for dive data, or CSV. Take your dives with you into any other dive software.
Available in: English, French, German, Spanish, Italian and Japanese.
