### 3/5 — Needs timer.

*2018-06-12, version 2.2*

A timer would be more efficient so you don’t have to keep watching the time and to stop it on 120 seconds is quite difficult as well as getting the readings correct, overall a good app but without the timer I think there’s better gas rate apps on the market for a lot cheaper

### 2/5 — None adaptive

*2017-10-31*

The app lacks the ability to modify values.  Cannot change value of gas for local area. Ours is about 1.2 not 1.4 and that makes a difference
Also limited meter dial choices mean less accurate calculation.   

I should be able to count revolutions and enter those to get better data values.  Not worth paying for this app.

### 5/5 — Gas Rate App

*2017-07-25, version 2.2*

As good as all the other apps from this supplier. Easy to use and reliable. Steve is so hard working to create fantastic software for this industry and has a wealth of knowledge and experience! Thanks again Steve!!!!

### 1/5 — Does not work

*2016-03-02*

Calorific value is the same for propane, natural gas and butane in metric mode no use at all

### 1/5 — Fault with start and end meter readings

*2015-07-28, version 2.0*

Since the last update I get the message that the initial meter reading is larger than the final reading even though they definitely are not. Initial reading 5,67 and final 5,77 and the message appears.

### 5/5 — Awesome

*2014-12-18, version 2.0*

This app is great. I use it every time I install a new boiler. It's give the gas reading in meter per hour and feet. Which is makes filling out the benchmark much quicker and easier

### 5/5 — Great app thankyou :)

*2014-12-13, version 2.0*

Thank you for the update I use this app a lot and it's now a lot better but please make it fit nicely for iPhone 6plus screen size and allow detailed results to all fit on the screen.

### 5/5 — The best gas rate app...

*2014-12-10, version 2.0*

Brilliant app with basic functionality.
Nice to see an email option, I would like an "open-in" option to directly transfer readings to other apps I use.
Also I would like to have an audio/alarm indicator for the last 10 seconds of a test on a metric meter.

### 1/5 — What's gone wrong, rubbish

*2014-11-21, version 1.2*

Been using this app on iPhone for last 2years and was brilliant. After recent update it won't even open, I have now deleted it and use another one that WORKS!

### 5/5 — iOS 8 IMPORTANT - DO THESE STEPS!

*2014-11-19, version 1.2*

When installing on iOS8 you must agree to ALLOW camera access on first install. If you haven't do this to make it work!! Go to the settings app, find has rate calc and tap it then tap privacy. Finally turn on allow camera a which makes the torch on the app work.
