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

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.

Great dive planning software!

The algorithm used in this app is fairly popular amongst other technical dive computers and their for fairly standardized. The user interface is what really makes this app rock! Everything that needs to be adjustable is and makes those adjustments incredibly easy. Better still is the price! You can’t normally touch software running this algorithm for this little cash.

Weather your into technical deco diving or even basic recreational diving this app has something for you. The gas planning/consumption data is helpful in any dive planning scenario.

I’ve bought VPM planner and other spendyer apps so I could run dive plans through multiple algorithms and HIGHLY prefer iDeco Pro’s user interface. When comparing deco schedules between the different algorithms, you’ll find there is very small subtle differences.

Great but needs an update

Great app! But they need to update the screen size to fit the new iPhones (Iphone X and newer)
