Jerky Tuner = unusable – Guitar Machine - SteamPunk Guitar Tools Review

I wish I had heeded another reviewers complaint about the tuner. On my iPhone 4 it jumps around so much that it's impossible to tune. Wasted 99 cents, then decided to go with guitar toolkit (tested on friend's phone). It might cost $10, but it works like a charm.
