WhatWatt Review

With an aim to making it easy for you to figure out how much your electrical devices are costing you to run, WhatWatt is an incredibly simple app. For the most part that's a pretty good thing, but it does make you long for a few extra features in there.

With no setup process involved, I'd advise going straight to the settings of WhatWatt in order to input the currency you want to use as well as how much one watt costs in pennies. Pretty much every currency imaginable is catered for here.

Once that's set up, switch back to the main screen of WhatWatt and you can get to work. There's a choice of looking things up according to watts, kilowatts, and 0.kWs, covering all the bases. It's just a matter of importing how much of one measurement along with how long you intend to use the device for, then WhatWatt does the rest. It lists the overall price as well as the individual price for each unit. It'll also tell you how much it works out to per hour.

That's pretty much all there is to WhatWatt, which does leave you wanting a few more features. I'd have appreciated a way of calculating numerous devices all at once, such as by inputting and saving individual devices. It'd be a great way of figuring out how much a room costs to run, for instance. Being able to share the results elsewhere would have been convenient too, even through simply copying and pasting. WhatWatt almost stops before it begins in terms of its potential.

As a basic tool though, WhatWatt is a quick and convenient way of making such calculations. But it's going to leave you wanting to be able to do more.
