Built by a musician for musicians, Beater is a full-featured and compact digital metronome, containing all the features you need to build simple and complex meters. On the Time and Tempo screen, set the overall meter and tempo. Then for more customization, dive into the beats view, where you can select the sound of individual beats, subdivide beats into parts, and turn beats on and off. Beater is accurate down to a single audio sample. The current version of Beater was designed for practicing polyrhythms in addition to standard meters. By setting a fast tempo and 11 beats per measure for example, the user can use a variety of sounds and accents to practice a repeating meter of 4/4 followed by 3/8. Like all my apps, Beater will always be free of ads and in-app purchases!

Beater costs $0.99 and Polyrhythm Explorer $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Beater holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Polyrhythm Explorer has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Beater's written reviews are positive against 88% of Polyrhythm Explorer's, so the app with the better star average is not the one people write more warmly about.
Beater ships an update every 12 months, Polyrhythm Explorer every 8 days. The most recent releases landed on August 1, 2026 and September 21, 2026 respectively.
