PolyMetronome vs True Metronome

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.

True Metronome is a metronome app for musicians, with a pendulum display, Italian tempo markings, and natural reverb sound. It supports tempos from 20 to 400 BPM, custom time signatures, and subdivision control. Its frame-accurate audio engine is designed for precise timing, while practice tracking displays daily, weekly, and monthly progress. Beat Detection uses a microphone to identify tempo from an audio source in real time. The maker says this processing happens on the device and audio is never recorded, stored, or transmitted. The web version works in modern browsers without a download and includes tap tempo and pendulum animation. The free version requires no account and has no ads during practice, but free users can use Tap Tempo up to five times per day. Free includes two skins and one bell accent. True Metronome Pro costs 9.99 USD once and adds unlimited Tap Tempo, a Tempo Trainer, live tempo detection, presets, more subdivision patterns, and other features. A special skin costs 0.99 USD once. The app is available on Android, iOS, macOS, and web.
