NovyDeco — Dive Planner

NovyDeco is a dive planning app built for every diver, from recreational to technical. Build your profiles on open circuit (OC) or on a rebreather (CCR), set up your gas mixes (Nitrox, Trimix) and compute your decompression with your choice of two models: Bühlmann ZH-L16C with gradient factors, or VPM-B, the bubble model.

Two algorithms, your own conservatism
Switch between models and compare them on the same profile. In Bühlmann, set your gradient factors — with separate values for open circuit, rebreather and bailout. In VPM-B, choose your conservatism level, from +0 to +5, with the VPM-B + GFS option to control the final part of the ascent. The comparator computes every variant at once and lines them up side by side: you see straight away what each setting costs you, or buys you.

Dive logbook
Save your dives, find them again by site, buddy, trip or date, and study each profile in detail: tissue loadings, saturation, total desaturation and no-fly time. Import your existing logbooks from Subsurface (.ssrf) or UDDF, and export them whenever you like.

Download dives from your computer
Connect your computer over Bluetooth and transfer your dives straight into the logbook, full profile included. A logged dive then reopens in the planner in one tap, to replay it or plan it differently.

Repetitive dives
Chain several dives with their surface intervals: NovyDeco carries residual gas loading from one dive to the next and gives you, for the whole series, the total desaturation and no-fly time.
