I did a school project and used this app to compute the cost of five lights in my kitchen. We replaced five 120 watt lights with five 28 watt LED. We will save more than $200 per year. This is a great app.

Easy to use and understand output. Release 3. Update looks good.

The app is a basic calculator to show how much money can be saved by replacing electrical stuff around the house with more efficient stuff. When I went through the house with my son replacing all the light bulbs with CFL's it shows the bulbs paid for themselves.

So easy to use! I'm off to turn my potential savings into real money. I think everyone should look at their energy consumption and see how much they could be saving. Awesome!
