Asks for feedback but button doesn't work, big mistake - no imperial option, only does metric, with Ads. Why would I pay for this!? Only plus side, it keeps the timer going if your screen turns off, hence the 2 stars.

couldn't do without this app its just the job, a 60 second timer rather than 2 mins is really useful, it gives you a GAS RATE in m3/h or l/s or ft3/h. it also gives you GROSS and NET HEAT INPUT's in MJ/h or KW or BTU's. i mainly use this app for HEAT INPUT in KW. AWESOME APP George.

Not as good as "Chronos gas Swiss army knife" on the Play Store. Too basic and dated for modern use.

No imperial meters only metric. Useless

it's all a gas engineer wants. It does exactly what it says, simple to use, it does metric and imperial measurements.
