Free version doesn't let you change the note to what you are striving for, instead you have to hope your not far from the right tune or you'll be there all day trying to tune one note.

Works really nice. Easy to use. Pretty accurate. Compared it to my strobe clip-on tuner. Highly recommended

Great, accurate tuner. Possibly the best on Play Store, and I have used and tried many. Will be using and testing over the next few weeks. My advice to the developer - don't fix what isn't broken. I'll be back to update. Thanks!
