The app has the following features:
✔ Built-in let-by/tightness testing timers
✔ Built-in conversion calculator
✔ Built-in guide with full gas rate calculations and let-by/tightness testing procedure
✔ Works on all types of meter
✔ Metric and imperial calculators
✔ Supports natural gas, butane and propane
✔ Save manual calorific values for improved accuracy
✔ Select between a 1 and 2 minute timer for metric meters
✔ Selectable timer alert
✔ Supports ¼ft³, ½ ft³ 1ft³, 2ft³ and 5ft³ imperial test dials
✔ Built-in torch
✔ Email results to any destination or share to other apps such as DropBox and Drive
✔ Timers do not reset when the device is rotated
✔ Timers will continue to run if the home button is pressed (metric alert will function also)
The metric timer can be set to either 1 or 2 minutes. For U6 and G4 meters one minute is sufficient, for E6 meters two minutes is recommended for accuracy. The timer can be set to an audible alert, vibrate, both or neither.
A guide has been built into the app with 6 pages:
• Metric gas rate calculations
• Imperial gas rate calculations
• Heat input calculations
• Let-by test procedure
• Tightness test procedure
• Tightness test permissible pressure drops
An extra Quick Converter calculator is included in the app for simple conversions between gas rates and heat inputs. Simply select the type of gas, enter a value, select the units, press the 'Calculate' button and the calculator will show all gas rates (cubic metres per hour, cubic feet per hour and litres per second) and heat inputs (MJ/h, kW and BTUs per hour) based on the CV.
The Tightness Testing function allows you to quickly select between the let-by and tightness tests and has an easy to use timer. No longer do you need to fiddle about with your phone's timer!
Calorific values can be entered manually (and saved) for more accurate gas rate calculation results. The calorific value of natural gas in the UK varies from about 38.3 to 40.5 MJ per cubic metre; this can mean a difference in the gas rate calculation of more than 5%! With this calculator you can add the CV for your area in the settings page and avoid these inaccuracies. The default values set for butane and propane are both the same as supplied by Calor and BOC.
A torch function is included with this app if your device has an LED flash.
This app requires the CAMERA permission to use the LED flash as a torch.
The Gas Pipe Sizing Calculator is an extremely easy to use app that will help you to select the right size pipes for installations using copper (up to 108mm), steel (up to 300mm) and PE (up to 315mm) pipes of sections up to 250m (820ft) in length.
To carry out a calculation simply select the gas type, enter the appliance heat input, enter the pipe length, the number of high or low loss fittings (guidance is given in the app), select the type of pipe and then press the 'Calculate' button.
The results will show the total equivalent length, the minimum pipe diameter (metric) that should be used and the pressure drop for that section of pipe.
For multiple appliances each section should be calculated in turn and the kW inputs for the appliances in each section added together for each calculation.
The maximum pressure drop from each appliance to the meter should be no more than 1 mbar for natural gas or 2.5 mbar for butane or propane. Adding all drops together using the minimum pipe diameters may cause this to be exceeded. Where possible, the results will also calculate the drop if the next larger size pipe diameter is selected on a section, this should help to ensure the right sizes are used throughout the whole circuit.
Please note: This app is designed mainly for the UK so supports metric pipe sizes only.
Input the initial meter reading, use the built-in 2 minute timer and then input the final reading. Press the calculate button and the results will then be displayed on the screen.
Gas rates are given in cubic metres per hour, litres per second and cubic feet per hour. Gross and net heat inputs are given in MJ per hour, kilowatts and BTUs per hour.

**PRO VERSION NOW AVAILABLE !!!
Calculates Gas Rate From Metric
and Imperial Meters for Natural,
Propane & Butane Gas.
If the boiler is running efficiently there may be no need to service it. Simply test the boiler with your analyser and obtain the oxygen, carbon monoxide and carbon dioxide values. Input the values from the analyser into the Gas Ratio Calculator, the CO/CO2 ratio will be calculated and advice also given on whether the boiler should be serviced or not.
Once you have your results you can email them directly from within the app or export them to another app that supports text files, such as Dropbox, Google Drive or Evernote.
- If you are travelling, perhaps there is an available WIFI hotspot, but are you sure your connection is fully configured?
- Perhaps your smartphone could use a mobile access (3G, 3G+, 4G, ...), but is it connected now?
So, this widget displays:
- If you are not connected to the Internet for the moment.
- If you are connected now, and which connection is used (WIFI, MOBILE).
Then, when you click on the widget, a new check is performed and a confirmation message is displayed. In this version, there is no screen to update your Internet connection.
Note: After the download, you need to manually take the widget in the application list and move it to your screen.
Please, this is my first Widget (very basic, isn't it?), so please send me an email with any remark or issue (I will try to fix it if I can).
If you struggle to add up the scores then take them away from your total, look no further. This app will do it for you with a few touches.
Input your initials, names, or team names in the 'Name boxes'. Play your three darts and enter the score in the 'score box' .
PRESS the 'Round Button', and the score will automatically be taken off from your game score.
At the end of the game PRESS 'new game button', this will swap players around for starting…. if you do not want to swap players, PRESS the 'new game' button again.
To alter the game starting amount (501) type in the score you wish to start with e.g. 301 then PRESS 'new game button'.
The 'Undo Last' button will undo 1 miss entered score from each player / team.
Once you get down to a finish, the darts scores required to get your finish will be displayed on the screen to help you. out.
GAS RATE.................... in M3/HR
HEAT INPUT (gross)..... in kW for older appliances
HEAT INPUT (net)........ in kW for newer appliances
it doesnt get much simpler no longwinded calculations to remember Instruction for use are here..
Even better now alterations can be made to the CV so calculations can be made for LPG
also you don't need to time the metric meter for two minutes anymore, the longer the meter is timed for the more accurate the calculation will be.
Now with a torch (for phones with a flash) makes life easier for meters under stairs or in cupboards.
This will tell you if the installation will meet the requirement of a 1mb drop from the meter to the appliance. If not adjust the pipe sizes to get an instant answer to see if it works.
Only works for metric 35,32,28,22,15,12,10,8 mm pipes
Steel pipes or imperial copper equivalent sizes could be used to give you a good idea, but will not be completely accurate.
No need to use calculations and tables to work out pipe sizes, it even tell you what size of gas meter should be fitted. This design tool completes all the hard stuff for you.
Pipe tables and pressure drops will only work upto 30m lengths of the chosen diameter. If you find that the pressure drop does not change when changing the diameter, then try a smaller pipe size it may work. ALERT view if wrong pipe diameter is entered, saves simple errors.
Removal of the tee pieces on the straight lengths, resistance is added when going around the corner only
Once downloaded the Licensing Service requires validation, this must be done via the phones CELLULAR DATA not through Wi-FI.
This gives you the option of working out ventilation when more than one appliance is fitted in a room.
For existing and new ventilators you can calculate the free air area of the vent to work out if its suitable for the appliance(s) it is feeding.
No more formulas and calculations to remember, read the heat input from the appliance data badge and press calculate.
