In trying other Metronome Apps, I found that the visuals were always lacking. Especially at a faster tempo, a basic animation like a moving box or a light that comes on briefly with each tick fails to give the sense of meter that I was looking for. Flashy Metronome uses flashing bursts of color that move around the screen in a metered pattern, each fading naturally. This creates an organic look that feels like rhythm, unlike visual effects that can confuse the eye. Other Features: -High precision timing, powered by AudioKit. -Tempo tap -Adjustable tick frequency -Meter -Optional use of camera flash

Verdict
The clearest difference is rating: Flashy Metronome at 5.0 against Keep Time's 4.0. Flashy Metronome also leads on in-app purchases (none vs 1) and ratings volume (7 vs 1). Keep Time's advantage is review sentiment (90% vs 50%) and update cadence (every 4 months vs every 17 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Keep Time sells 1 one-off in-app purchase. Flashy Metronome asks for nothing beyond the download.
Flashy Metronome holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Flashy Metronome has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of Keep Time's written reviews are positive against 50% of Flashy Metronome's, so the app with the better star average is not the one people write more warmly about.
Keep Time ships an update every 4 months, Flashy Metronome every 17 months. The most recent releases landed on October 6, 2026 and October 7, 2026 respectively.
