Rhoops

Rhoops is a circle-based metronome for rhythm training. Use it as an everyday metronome, or build up the more advanced things — off-beats, N-tuplet subdivisions of 16th notes and sextuplets, laid-back timing — with a simple "choose, color, and play" feel.

■ Choose, color, play The 4 / 6 buttons under the BPM switch the accent positions on the inner ring. Pick a sound from the palette and tap an accent position to "paint" it — like coloring in, you can place a sound anywhere you like. Tap the same spot repeatedly to cycle the volume (loud → mid → soft → off). Removing a sound with a flick or the eraser is just as easy. Pro adds an L6 mode for laid-back practice.

■ N-tuplets with the outer ring Add the outer ring to practice N-tuplet subdivisions of the 16th note (N = 1–10). Tap an accent position on the outer ring to move the starting accent anywhere you like. With Pro, you can also add a sextuplet-based outer ring.

■ Made for practice • Downbeat fade-out: mute the downbeat accent from a chosen bar (and bring it back) — a self-check for rushing or dragging. • Accent-rotate mark: shift every non-downbeat accent left or right at once. • Theme colors: blue, red, white and black. • Pattern save: store your favorite patterns and recall them with one tap. • Tap tempo: tap the screen to set the tempo.

■ Free / Rhoops Pro (one-time purchase) The free version (with ads) includes all the core features. Rhoops Pro removes ads and unlocks L6 for laid-back practice and the sextuplet-based outer ring (triplet-family subdivisions).

Great for • Anyone who wants to practice off-beats and 16th notes on a metronome • Players who want laid-back feel and groove in their body • Anyone practicing N-tuplet subdivisions and polyrhythms
