Thanks for creating this! I love the simplicity and works great. I do have two feature requests: 1. Support repetitive dives. Even if you just add the ability to specify RNT in addition to minutes (so the RNT time doesn't count towards gas calculation). Bonus points for providing a way to calculate RNT. 2. Make it so I can select/copy the text I'd be happy to beta test or help out adding features.

I rated this low originally because the setting to ascend at 10ft per minute after first stop caused weird runtimes when doing stop to gas switch to EAN32 at 130 ft. I recommend disabling that in settings. I increased rating to 5 stars because of the fast and helpful response by Easy App Master.

Thank you for updating your feedback. This option is enabled by default, because after a typical gas switch such as Tx18/45 to EAN50 at 70ft, helium off-gases independent from depth so there's no benefit from an immediate fast ascent to the first deco stop and divers prefer to slow down. With air as bottom gas, it's different.

Less is more Very good app. Better than most deco planners. Excels in simplicity, lightweight and does everything you need. No ads, no spam or whatsoever. Kudos to the creator. Respect
