Best meter
Beutiful App...Recommend it to everyone...
Simple and useful app without unnecessary ads.
Unbelievably simple, user friendly and informative, still to see how many ads pop up but so far no ads and if the "test" ad strip is all we have to worry about then 5 stars.
Good for solar power calculations.
Very good app
