Glitchy

Waste of a dollar. Every time I inadvertently tipped my iPhone4 into landscape mode, and then uprighted it, the program display would get all screwed up--as if I had zoomed in to see just the lower left part of the display. And it would remain that way until I killed the program and restarted. Very annoying. Crashed once as well. Deleted and wrote it off as a loss. However, when it worked it seemed OK. Plain, easy to read meter, quick response, etc. FWIW.
