Metrognomicon vs 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.

Metronome+ combines a metronome, chromatic tuner, setlist, recorder, and pitch player in one app for iPhone, iPad, and Mac. The metronome supports customizable accents, tap tempo, and seven custom accent colors. Its tuner and pitch player can run simultaneously with the metronome. Auto loop changes tempo automatically over time. Setlist mode saves favorite settings, while recorder mode lets users record and share practice. The app is free to download, with in-app purchases unlocking modes. The US listing shows Unlock Everything for $9.99 and separate listed purchases for $3.99 each. iPhone and iPad require iOS 15.0 or later and iPadOS 15.0 or later. Mac support requires macOS 12.0 or later and an Apple M1 chip or later. The developer asks users to email bug reports and feature requests.
