Great app

:
It does all it says and that's all I expected. Some idiots in they're reviews always want more and down grade their rating because of it. Like Ugly. How about the kitchen sink too. And let me guess, you want all those extras at no extra cost. Poor app. It doesn't say anything about using it for power. For the dummy who wants power formulas. They're there stupid. Look under "POWER" not ohms. For the gal who couldn't get it to work. I bet your just the best in the field.

5/5 stars

Electronic Formulas

:
Wow! This app is a huge help. I'm just starting year #2 in an Electronics Course, this app has really helped me get my head back in the game after some summer fun. Big time saver. I especially like the way you can change the formulas and units around. The wiki links are awsome too. Need to run a spell check though...........
