Bubble Deco

Now plan with the cylinders you actually own. Track your tanks, check your CCR bailout gas bottle by bottle, and enjoy a fresh new look across the app.

Plan your decompression dives with confidence.

Bubble Deco is a precise, modern dive decompression planner built on the Bühlmann ZHL-16C algorithm with full gradient factor support. Designed for recreational technical divers who want a clean, fast planning tool on their phone.

PLAN SMARTER Enter your bottom depth, time, and gas mix. Add deco gases. Compute your plan in seconds - full stop schedule, runtime, CNS%, OTUs, gas consumption, and a visual depth profile with deco ceiling overlay.

GRADIENT FACTORS YOUR WAY Dial in GF Low and GF High to suit your conservatism. Each deco stop displays its interpolated gradient factor so you know exactly how the plan is constructed.

MULTI-GAS SUPPORT Add up to three deco gases with one-tap standard presets: O2 6m, EAN50 21m, Tx35/25, Tx21/35.

GAS BLENDER BUILT IN Plan your partial pressure fills with the integrated gas blender. O2 and He fill steps calculated automatically.

DIVE LOG Log your dives and track your stats - total bottom time, deepest dive, and recent plans all visible at a glance.

AVAILABLE IN 6 LANGUAGES English, French, German, Spanish, Italian, and Japanese. Help us improve translations via the in-app feedback link.
