M.ETRO is a really light metronome. Swipe up or down (or touch) to increase or decrease BPMs. Tap on BPMs in the center to make metronome start. That's it, stop. Goodbye.

Verdict
The clearest difference is in-app purchases: M.ETRO at none against Flynth's 1. M.ETRO also leads on update cadence (every 3 days vs every 4 months) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.
