## What is RuntimeX?

RuntimeX is a dive planner designed for advanced recreational and technical divers who want to create and manage dive plans in a simple, fast and reliable way.

  It supports Open Circuit Multi-Gas and Closed Circuit Rebreather (CCR) dives, allowing you to plan complex profiles with gas switches, multiple setpoints and
  detailed decompression.

  RuntimeX integrates the Bühlmann ZHL-16C and VPM decompression algorithms, letting you analyze different decompression strategies and generate complete
  runtimes for every dive.

  Key Features

  • Open Circuit Multi-Gas dive planning
  • CCR support with setpoint management
  • Bühlmann ZHL-16C and VPM algorithms
  • Automatic decompression calculation
  • Nitrox, Trimix and Oxygen support
  • Gas switch management during the dive
  • Detailed runtime analysis
  • Dive profile visualization
  • Save and edit dive plans
  • Quick duplication of existing plans
  • Intuitive interface optimized for field use

  Designed for technical diving

  Whether you're planning a simple recreational dive or a complex technical dive with Trimix and accelerated decompression, RuntimeX helps you organize your plan
  in seconds.

  The app is designed to provide quick access to essential information, with a clean interface focused on planning.

  Disclaimer

  RuntimeX is a dive planning tool. All generated plans must be reviewed and validated by the user before use. The user is solely responsible for the correct
  execution of the dive and for compliance with all applicable safety procedures.


## Version history (last 4 releases)

### 1.0.4 — 2026-06-16

- Contingency planning — simulate the dive with conservative margins (+3/+6 m depth, +5/+10 min bottom time) and compare results against the base plan in both
  the output panel and PDF export
  - Live MOD/ppO₂ indicators — switch depth auto-updates whenever you change O₂% or ppO₂ limit; visual warning when switch depth exceeds the calculated MOD
  - Improved lost-gas PDF section — each scenario now includes a full deco stop schedule and per-gas consumption table
  - Refined layout — dive levels section moved directly below the primary plan card for a faster input flow
  - Minor dark mode UI contrast fixes

### 1.0.2 — 2026-06-14

- Physically correct CCR gas consumption (loop top-up diluent + metabolic O₂)
  with cylinder volumes and low-gas warnings.
  - Default gases in settings (OC bottom, CCR diluent, deco/bailout) auto-filled
  into new plans.
  - Full-screen landscape, scrollable dive profile with a sticky depth axis and
  a details panel.
  - Gas-switch markers and ppO₂ alerts plotted on the profile.
  - Gas shown per deco stop, highlighting gas changes.
  - New "+" button to start a fresh plan.

### 1.0.1 — 2026-06-13

What's new in 1.0.2
    • Multilevel dive planning: add multiple depth levels with per-level gas selection and drag-to-reorder
    • New VPM-B decompression algorithm, alongside Bühlmann ZHL-16C with gradient factors
    • Configurable last deco stop depth: choose 3, 4, 5, 6 or 9 m
    • Last stop depth now included in the PDF report
    • Bug fixes and stability improvements

### 1.0 — 2026-06-10

No release notes.
