A suggested improvement: find a way to play the tuning pitch while keeping the tuner visible. this would allow you to play against the pitch (with ear buds) and get visual feedback. for extra credit, support some other pitch voices (like a cello drone). otherwise a fine tuner & metronome app!

Very good app I wish there was a translator the text limits small i need more txt when giving ppl feedback wish there was a reply option so u don have to comment on ur own recording or find the recording to see if they replied Korean users comment & I cant type their name It would be cool if there was a friends option and u accept requests so you can share certain records to friends give feedback & combine recordings then post them it would also be useful to search up users recording & add tags

This app is absolutely awesome. it's got so many features I didn't even know I wanted in a tuner/metronome app. the only reason I give it 4 stars is because when using the speed trainer, there is no loop function and it will just stay at the speed you set untill you press the button to start over, and when you do there is no count in or anything so it starts climbing immediately while you are trying to get back into position. if they add a loop and 4 count to the speed trainer, 5 stars all day.
