First steps
This page introduces the MV-Plan interface and the usual run through a first plan.
Opening the application
MV-Plan opens straight in your browser. No account, no login. You can also install it:
- On a phone: use the App Store (iOS) and Google Play (Android) buttons inside the application.
- On a computer: a desktop version is available.
On the very first launch, a dialog offers to pick your language. You can change it at any time in the Settings.

The interface
The layout depends on the size of your device.
On a computer
On a wide screen, MV-Plan shows a dashboard of three columns side by side:
- Gases (left): your mixes.
- Plan (centre): the dive segments and the calculation.
- Profile (right): the chart and the tissue saturation.
You can resize each column by dragging the vertical separators; the widths are remembered. A sidebar on the left reaches the Plan, the saved plans, the settings and the theme switch.

On a phone
On phones and tablets, one view shows at a time. A tab bar at the bottom of the screen moves between the pages: Gases, Plan, Profile and Saved. The cogwheel button opens the settings.

The pages of the application
| Page | Purpose |
|---|---|
| Plan | Build the dive (segments), run the calculation, read the stops and export. |
| Gases | Declare your mixes (OC), your diluents (CCR) and the configuration of your cylinders. |
| Profile | Look at the dive chart and the saturation of the compartments. |
| Saved | Save, reload, import and export your plans. |
| Settings | Set the algorithm, the rates, the consumption, the environment, and so on. |
Light or dark theme
A button switches between the dark and the light theme, to suit you and the light around you. The choice is kept for your next visits.
Walking through a first dive
- Set your parameters once in the Settings: algorithm, gradient factors, ascent rates, consumption (RMV / SAC), units. These are remembered and serve every dive.
- Declare your mixes on the Gases page: composition, ppO2 max, and the configuration of your cylinders (volume and pressure).
- Build the dive on the Plan page by adding one or more segments (depth and time).
- Run the calculation with the Calculate Decompression button.
- Read the results: stops, total runtime, TTS, gas consumption per cylinder, and the profile chart.
- Export or save: produce a printable PDF or store the plan in your saved plans.
See the dedicated pages for the detail of each step.
