Super tuner
I have a few tuner apps and always turn to this one for tuning my harp. It occasionally has difficulties picking up the higher frequencies of the instrument, but it still outshines the other tuner apps by a long shot. The metronome is a lovely added feature and I also use that frequently. Great customizable features. Highly recommend.
