Real Bühlmann decompression planning, in your pocket. One price, yours to keep – no subscription, no account, no ads.
Bubble Deco is a precise, modern decompression planner for technical divers. It runs the Bühlmann ZHL-16C algorithm with gradient factors entirely on your phone, so it works offline – on the boat, at the quarry or on the dive site.
PLAN A DIVE IN SECONDS
Enter depth, time and gas. Bubble Deco calculates the full stop schedule as you type: runtime, every deco stop, CNS%, OTUs, gas use and a depth profile with the deco ceiling drawn over it.
GRADIENT FACTORS YOUR WAY
Set GF Low and GF High to match your training and conservatism. Each stop shows the gradient factor it was calculated at, so you can see exactly how the plan was built.
OPEN CIRCUIT, NITROX, TRIMIX AND CCR
Plan air, nitrox and trimix with as many deco gases as your dive needs – add and remove stages freely, or use one-tap presets (O2 6m, EAN50 21m, Tx35/25, Tx21/35). Plan closed-circuit rebreather dives with set points and as many bailout gases as you carry.
BAILOUT WITH THE CYLINDERS YOU OWN
Save your tanks – label, serial number, gas and service dates – then tick the ones you're carrying. Bubble Deco checks your CCR bailout gas bottle by bottle and flags anything that falls short.
GAS TOOLS
Partial-pressure gas blender, MOD, ppO2, EAD, END, EADD, NDL, best nitrox and best trimix for a target depth.
BUILT FOR REAL DIVING DAYS
Multi-level dives, repetitive dives with tissue loading carried over, altitude diving, per-diver profiles, a dive calendar and a dive log with your stats. Share a plan card with your buddy or export to UDDF/CSV.
SIX LANGUAGES
English, French, German, Spanish, Italian and Japanese.

What's new in 1.4:
• Your dive in plain English: in Recreational mode, every plan now comes with a simple summary – how long you can stay, how fast to ascend and your safety stop – highlighted when you're close to or beyond the no-stop limit.
• As many gases as you need: add and remove deco and bailout gases freely, for dives with three or more stages.
• Saved CCR plans now show your set point and diluent.
• Clearer bailout guidance.
Plus a round of refinements and fixes. Safe diving.
