Works well enough

The battery in my tuner died but I didn't have any more batteries around the house so I thought I would download a tuner app. My ukulele was HORRIBLY out of tune but this app fixed it! My only issue with the app was that it was incredibly slow when I was trying to tune. I plucked the string I was tuning and it wouldn't respond right away for me. I thought it was telling me to keep tightening when I was actually too tight, if you know what I mean. This app does gets the job done, although there are better tuners out there.
