Metrognomicon vs True Metronome

Metrognomicon is a free iPhone metronome for practicing music that changes tempo. It plays ordered tempo segments and can switch automatically between them. Set each segment by beat count or elapsed time, then choose looping or a single run that stops at the end. Tempo settings span 40 to 240 BPM, entered with a slider or tap tempo. Six click sounds are available, and an optional count-off plays the final four beats before every tempo change. The interface lists light, dark and Brushed Metal themes. The maker describes the app for classical players, students working on difficult passages and musicians practicing pieces with tempo changes. Metrognomicon runs on iPhone, makes no network connections and stores sequences and preferences on the device, supporting offline use. The App Store listing limits it to iPhone. Support is available by email at [email protected]; problem reports should include the device model, iOS version and app version.

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.
