A full deco planner in your pocket, and a free toolkit for the rest of the dive.
Dive Kit plans open-circuit, trimix, and CCR dives with Bühlmann ZH-L16C and the gradient factors you choose. You see every assumption behind a schedule, and a share link reopens the exact plan on your buddy's phone or in any browser.
Everything runs offline. The display stays readable in direct sun, the controls suit cold, wet hands, and routine tasks take seconds.
DECO PLANNER (PREMIUM)
The one tool you pay for.
- Multi-level profiles with automatic gas switching and unlimited segments
- CCR: depth-keyed setpoint schedules, diluent switches during deco, and a full open-circuit bailout from any point in the dive
- Stop times to the second (MM'SS"), or rounded to the minute or 30 seconds; the table always matches the engine
- PPO₂ caps per gas by O₂ content (lean, mid, rich bands), so each gas switches in where its PPO₂ allows
- Contingencies: deeper, longer, lost gas, or build your own
- Per-stop PPO₂, CNS% and OTU, gas density, and consumption per cylinder with reserve warnings
- Oxygen breaks on long O₂ stops
- Repetitive dives with tissue loading carried across the surface interval
- Share by QR code or link; every setting travels with the plan
- Export deco tables and printable slate images
- Compare plan variants side by side with graph overlays
