PolyMetronome vs Tempo by Frozen Ape

PolyMetronome is a metronome for musicians building practice around complex rhythms. Simple Mode covers time signatures from 2 to 32 beats, tap tempo, subdivisions, and visual beat indicators. Poly Mode runs two metronomes together, with separate beat counts, volumes, stereo positions, and sounds. Alphabet Mode provides 32 subdivision patterns for 16th-note and triplet figures, with notation and multi-bar loops. Score Mode lets users assemble multi-section compositions with individual tempos, repeat counts, and speed-training settings, then organize scores in folders and sync them. Bar Muting can silence beats in cycles or randomly at an adjustable probability; Speed Trainer moves from a starting BPM to a target through linear or stepped changes. Practice Log records dates, notes, BPM, and duration. The app includes 13 sounds, beat flashes, vibration, beat-position indicators, two themes, and six languages. It runs on Android, iOS, and the web; the web app supports Chrome, Firefox, Safari, and Edge. The free plan is free and includes Simple Mode.
