Great app!! Brilliant app...saves me loads of time. Checked the calculations the first few times... always spot on. Calculate button pops up when you push menu button. (button to the left of the home button.)

Works very well, just remember to put a decimal piont before your readings to get an accurate answer!

Thanks Didn't work for me, could input readings but no calculate button on bottom. Using s3 Samsung galaxy Thanks for pointing out my stupidity. Great app works now Updated score

Great app! I have checked this with the calculation for gas rating and it's spot on. I use this for gas rating all appliances.

Read the instruction link Installed and read the simple instruction, brilliant free app which will save time and lookups in customer houses, checked on several appliances so far and 100% for me. AND ITS FREE :)

Doesn't work Used to work brilliant on my iPhone but doesn't have a calculate button on my Samsung s5. Fix it

Paul Gilbert

Brilliant app Needs updating for the samsung galaxy s5 no way of getting to the menu button now that samsung have changed the way the phone is layed out unfortunately this app has not kept up so unable to calculate figures. I will up this back to the 5 stars that it rightly deserves once this is fixed.

James Gibbons

HTC one sv Couldn't calculate it.

Tom Sewell

Good Does the job and is accurate. Would like a button at the bottom of the page to calculate though instead of clicking the menu.

A Google User

For Gas Engineers like myself its simply BRILLIANT very useful & easy to use thank you

Paul tiffin

Not accurate Try entering 100 for start reading and 101 for end reading. Time for 1 minute. Calculates out as 30 m3/hr. Please rectify before using. To use a programme like this you need to have 100% confidence in the calculations.

A Google User

Great app, saves me the hassle searching through corgi chart

A Google User

Great app for the gas engineer.

A Google User

No calculate button Does not work. No calculate button

A Google User

A Google User

Poor app compared with the iPhone version

A Google User

Cracking app tested it against manual calculation and almost identical readings

Bob Davis

Good app once I had read other reviews and realised the calculate button appears when you press the menu option, but it would help if this was clear in the instructions

A Google User

gas safe fitter someone please convert iPhone version to android, this version is crap. no calculate button

A Google User

GB Brilliant. All my mate's use it terrific!

Steve Thomas

Excellant for that service, gas rate at a click away

Neil Cooper

Dangerously incorrect! Generally I like the the app, but there is a serious error in the calculations! Try putting an initial reading of 0.750 and a final reading of 0.830 then let the timer run for 2 minutes and then press calculate. You get the correct answer of 24kW. Now try the same thing again but only let the timer run for 2 seconds - you get the same answer! It doesn't take the actual time of the test into account and hence could be dangerously misleading! PS the IOS version is the same!

super nobby

Can do this simple enough with a pen and paper but yes not as quickly and I'm sold on this new fangled ideas would highly recommend to any budding gas engineer.

David Chand

Very good A+++ Just the best app I've used to gas rate

Gary Wilkinson

Loved this app. But I've just upgraded to Samsung s7 and there's no button to calculate? Hope there's a fix available

Tom Wise

This app worked really well until my s6 upgraded to marshmallow and now the calculate button is missing. Is there an update coming for the app soon

Howard Brower

Howard B It does still work on the new Samsung phones, just keep your finger on the bottom left hand button for a few seconds and calculate comes up.

Roy Sinclair

Upgraded to samsung s7 and now has no calculation button. Needs a fix. Ill have to use another app untill sorted

Dave Ellis

Since s6 upgrade to marshmallow calculator button has gone. Can't use the app until this is sorted. Before upgrade brilliant app use it many times a day.

A Google User

Calculate button was hard to figure, on my defy it is the menu button which is also reset etc. Reasonable app which i can see me using a fair bit.

Great app any body can't find calculate try the three little dots on right hand side of phone

A Google User

Where is the calculate button
