Metrognomicon vs Tempo by Frozen Ape

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.
