Metrognomicon
What it is
Metrognomicon is a free iPhone metronome for practice sessions that move through planned tempo changes. You can build sequences from tempo segments, setting each segment by a number of beats or by elapsed time. A sequence can repeat continuously or play once and stop. Tempo settings range from 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 offers light, dark, and Brushed Metal themes. Metrognomicon runs on iPhone without network connections and stores sequences and preferences on the device, supporting offline use. The maker describes it for classical players, students working on difficult passages, and musicians practicing pieces that change tempo. It is free, with support available by email at [email protected].
