Dont bother....

At first I enjoyed this app- the whole 2 or 3 times I managed to use it before it completely froze. It refused to work anymore because I turned down the supposedly free upgrade(which when reading the fine print you see it isnt in fact free). Then when I didnt hit okay to receive FUN & INFORMATIVE & FREE facts about the metronome, it refused to return to the main screen of the app & ceased to function completely.
Pointless app unless you want to deal with the Gordian Knot of apps.
