Works great I blend tanks all the time for work, this is quick and as accurate as anything else I've found, wish it didn't round to the nearest whole percent for existing gas but it doesn't seem to effect that much.
No longer works. Just purchased a galaxy s5 and I can no longer get into the setings. Please fix.
Craigp Couldn't find out how to change units at first. Now happy great app
Does not allow conventional Heliair blending for Trimix. Can't start with 100% Helium in tank for air topping.
Got everything you need for blending gas
Wow!! A literal life saver. Perfect for checking my mixes.
Added support for blending using gases other than oxygen in settings under "Rich O2 Mix."
