JDeco is the first and only dive decompression program that is available for JAVA enabled mobile phones and PDAs. It utilizes the Varying Permeability Model (VPM-B) and Bühlmann's decompression algorithm with Erik Baker's Gradient Factors for mixed gas decompression in open-circuit (OC) and closed-circuit (CCR) diving mode.

On a dive boat or on any other dive trip you try to minimize the stuff you have to carry along. Your mobile phone, however, will always be with you. With JDeco you can give your phone an additional use - you can use it to plan your dives! Additionally you can use it to calculate your gas mixings. Now you can leave your notebook (or desktop PC ;)) at home.
