Technical dive planning and gas mixing OVM Diveplanner is an OC/CC (rebreather), mixed gas, multi-level, repetitive dive, decompression planner based on Bühlman ZHL/16C with configurable gradient factors. It tracks CNS and OTU's. Auto-calculates bailout profiles when in CCR mode. Create your dive profile by entering a list of depths of adding waypoints in the visual planner mode. Use predefined gasses or add your own custom mix. Also provides several gas mix tools for estimating gas results when topping off your tanks. This will give an estimate if boosting tanks leads to undisiarable results, before mixing. The app contains a user manual which is also available online at https://www.ovm-planner.com/user-manual.html. The app is intended for certified who whish to create an estimate of their dive profile and gas usages when executing deep decompression dives, helping in determining the required amount of decompression gas or bail-out gas needed. It can also be used to create an ascent profile to which you can fallback on when the divers computer fails underwater, or use for sanity checking you dive computer during the dive. The app works standalone and offline. It does not require an account and does not store any data except app settings such as breathing rate and entered dive settings. No external connections, software or hardware is required. No subscribtion of in-app purchases needed or possible.
