Best tuning app.
I play in a touring string quartet and over time my group has tried many different terrible tuning apps. This is the only one we trust at this point, it works really well and offers many features on the tuning end of things. Im tempted to give it 4/5 because there is no metronome function or whatever, but to be honest its a tuning app. They never said it should have a metronome so there you go.
Best one on the market.
