Tempo by Frozen Ape vs True Metronome

Tempo by Frozen Ape is a metronome app for Android and iOS, with free Lite editions and paid versions. The iOS app supports tempos from 10 to 800 BPM and lists 35 time signatures, six rhythm patterns for simple meters, and three for compound meters. Users can save presets in setlists and share them by email as Tempo files or text; Android setlist files also work with iOS. On iOS, practice tracking can count bars or elapsed time and stop playback when a chosen limit is reached. The listed audio and display options include 14 sound sets, voice counting, vibration, stereo panning, pulsating LEDs, and full-screen display. The app also lists support for external input devices such as AirTurn, iRig BlueBoard, PageFlip Cicada, and headphone remotes. Tempo Lite is free on both platforms, with in-app purchases; the Android Lite edition contains ads. The paid Android app costs $1.49, paid once, and the iOS version costs $2.99, paid once. Both paid editions include in-app purchases.

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.
