Tool for planning staged decompression dives for technical divers. Supports open circuit and closed circuit rebreathers, multi-level and repetitive dives, nitrox, trimix, altitude adjustments, metric and imperial measurements. Keeps track of gas consumption, OTUs and CNS. Per dive configurable ascent/descent rates, last stop/stop interval settings and RMV/MOR. Any combination of OC and CCR planning is possible (CCR dives with OC levels/deco etc.). One tap access to lost-gas, bailout, deeper & longer contingency profiles. Constantly displays updated plan details as changes are made, and uses color highlighting to suggest best mixes. Dive plans can be stored in a bookmark folder for convenient reuse. Plans can also be exported via email or pasted into any other app. Features both VPM-B (based on Erik C. Bakers work) with configurable conservatism and ZHL16-B with configurable gradient factors for calculating decompression profiles. Also supports VPM-B/GFS.
