A complete multiple dive / multi-level dive planner for the technical diver. Includes support for Open Circuit Diving as well as Closed Circuit Rebreathers (CCR).

Includes decompression stops, gas usage, CNS tracking, OTU tracking, Surface Interval tracking and many other features. Currently implements the Buhlmann ZHL16/C with Erik Baker's GF algorithm.

Open Circuit - Scuba : Supports Air to TriMix (any combination of O2/He/N2), with an unlimited number of decompression gases. Includes Thirds support for planning dives.

Closed Circuit (CCR): Supports any O2/He/N2 combination for diluent. Automatically generates bailout plans based on entry of bailout gases. Features a Cave/Wreck bailout option for overhead environment bailouts and gas planning.

Gas Fill/Mixer: Allows for filling of Air, Nitrox and Trimix via a simple, easy to use interface.

All settings are configurable via the iPhone Settings.

Supports US Imperial and Metric

Ratings and Reviews

Good, Simple to Use


The most recent NEDU data seem to indicate gradient factor based dive plans are more reliable than VPM and various bubble models that get you out of the water faster. Not having VPM is only really an issue if you need to match the plan to a dive computer that only offers VPM. You should also be checking technical dive plans against multiple sources, so I wouldn’t rely solely on a single app anyway. If this had settings for altitude diving and fresh water, I’d give 5 stars.

Antiquated algorithm but adequate...


Still an antiquated algorithm with the addition of more rainbow farting unicorns. Limited but adequate for light to moderate technical dives. VPM would make this app a real winner and suited for more advanced mixed gas OC/CCR dives. Good for the money tho! V-Planner is still the better choice for the serious technical diver.

Good app with too glitches


As general speaking the app do the job but with some considerations, for example when you plan a deco dive within the app and the dive plan throws you lets say a deco stop at 9m for 8 minutes and you set a leg at the same deep for 10 minutes the app dont recognize the extended level and still set the 9m for 8 minutes stop wich total time will be 18 minutes (extended level plus real deco stop) very diferent from the original 8 minutes or even 10 minutes level.

Also would be great to controll the ascent rate, descent rate and sac more precisly . My real deco sac is under the minimum value on the app.

Delete waypoints or legs can be tricky because the app delete the waypoint but dont keep the info for the other wp instead the app overlap the info you are triying to delete with the next wp.
