## What is Bubble Deco?

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.

BUILT BY ICEBUBBLE
Bespoke software developers based in the UK. icebubble.co.uk

Bubble Deco is a planning aid only. Always dive within your training and certification. Not a substitute for a certified dive computer.


## Version history (last 4 releases)

### 1.3 — 2026-06-29

What's new in 1.3:

• My Cylinders: save the tanks you own with their label, serial number, gas mix and service dates, then pick them when planning your CCR bailout.
• Smarter bailout: tick the cylinders you are carrying and the planner checks each gas, flagging anything that falls short.
• A brand new icon set, drawn especially for Bubble Deco, for a cleaner and more consistent look throughout the app.
• Settings now save automatically as you change them, no more Save button.
• Edit a planned dive straight from the calendar.

Plus a round of refinements and stability fixes. Safe diving.

### 1.1 — 2026-06-16

**What's New in 1.1.0**

Dive Profiles
Set up profiles for yourself and your buddies - each with their own gas consumption, gradient factors, gas mixes and cylinder. Pick a diver on the planning screen and everything fills in automatically.

Dive Calendar
Plan a whole trip's worth of dives across multiple days. Bubble Deco threads your tissue loading continuously from one dive to the next - including surface intervals and repetitive days - so your decompression is calculated for the dive you're actually on, not in isolation. Altitude diving is fully supported, with surface pressure adjusted for your site's elevation.

Share Your Plan
Turn any computed dive into a shareable card - depth, deco stops, gases and run time - ready for WhatsApp, Instagram or your camera roll.

Export Your Log
Export your dive log as UDDF, the open standard, to move your dives into other dive software. CSV export is there too.

Also in this release
- Faster, clearer deco stop list
- Polished dark mode
- Available in English, French, German, Spanish, Italian and Japanese
