DiveMan

The app does what it says it will. Only have 2 ideas for improving it, but all in all, it's very functional. 1. The weight calculator does have an option for single back mount. 2. The blending function doesn't allow you to adjust the blending gas. Other Than that, it's a great app and I share it with many students. If the app developers fix these 2 small issues I will update to a 5 star review.

As a dive shop worker with an android and comparing it to the more expensive nitrox tools my boss uses on iphone, I would say both offer very comparable options except that this app is free instead of the 15usd for nitrox tools so, thanks a lot for helping a newbie gas blender get started without additional fees, would be nice to have a premium version that offers a few extras like tutorials for complete beginners but overall a very good free app that works well.

Great, Im a good diver but bad maths, this makes things work. Also good to double check your maths if you think your good. Many additional features which are cool and helpful.
