Tick - Minimal Metronome Lifetime Deal

Set your tempo exactly the way you want. Use large chevrons to nudge the BPM, drag the number for fine control, tap the tempo to lock in a new beat, or tap the subtle ±5 zones to the left and right of the large BPM readout for instant jumps. Choose from five carefully tuned click sounds to match your instrument and playing style, and play the metronome through external speakers using AirPlay when you need more volume. The same app is also available on macOS, with a native desktop experience including keyboard shortcuts and an always-on-top window mode. The metronome continues playing in the background and works on the Lock Screen, so you can keep practicing without keeping the app open. Everything is included, forever.
