### 2/5 — 1 page app.

*2019-01-25*

The page you see as the example is the page you get, and that’s it. Once you have filled in your energy cost you change the Watts of the device and it does the calculation. 
No storing of devices or any variations, just the one page, which you could undoubtedly work out yourself.....

### 3/5 — Simple & effective

*2018-07-13*

Nice and simple but please update for iPhone X screen size as the power(watt) input is hidden by the iPhone X notch at top of screen.

### 5/5 — Simple but great

*2012-06-06*

This is what I was looking for and it's a simple but great app. Thanks to the developer.
