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.
Cannot switch to metric on Galaxy S6. Was such a great app and I'm sure will be again when menu issue is fixed.
No longer works. Just purchased a galaxy s5 and I can no longer get into the setings. Please fix.
Can't switch to metric On a galaxy s7 I can't change units to metric. Any workaround ?
Can't convert to Metric, even though the description says it can. Sorry, but refunding...
Craigp Couldn't find out how to change units at first. Now happy great app
Added support for blending using gases other than oxygen in settings under "Rich O2 Mix."
