More precise than others

Works good for me being a beginner.

Not really very useful

This app looks impressive but its not that useful. The graphs are too jerky and I can't see any reason to use them. The tuner is also jerky. There are better tuners around in the app store. I've tried this app on an iPhone and an iPad and different ukes and theres no difference. Sorry Ullrich, it needs work. I feel i've wasted my money.

Tunes only sopranos

Tunes really well, but need to pay for the rest of the other types of ukes such as concert, tenor and bass
