Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
- 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
