The latest IOS26 version is very hard to use. Drop down menus doesn’t work. Still love the app and I’m fully convinced Ross will fix it.

В программе есть все что нужно. Считает дайвы по VPN и GF. На выбор. Если нужно считать чистый кислород- ставьте Найтрокс 99%. Чистый кислород 100% программа не считает. Do everything I need. Can calculate dive using either VPN and GF models. If You need O2- set nitrox 99. App cant count 100% Oxygen.

This app is abandoned, use at your own risk. It doesn’t work with the latest iOS update. The back or save buttons crash the app on any device I use.

The latest version 1.94 crashes on my Iphone. Every time I try to change the settings it crashes. Please fix it Ross. It’s the best planner available. Same with V-Planner 2.94.

Main issue is the user interface. Poor 80’s usage level. Gas bending tools are rather limited. The best feature is max dive plan based on available gases. I’m better off with some other 20€ deco planner and 5€ blender tool. Odd hype around this multideco, IMHO.

La empresa anuncia que tiene modo SCR como el V-Planner pero en la app solo ofrece planificación en OC o CCR
