What Chronal is
Chronal is a free, ad-free Android metronome and tuner for beginner and advanced musicians. Its timing tools include beat and subdivision visualization, tap tempo, custom time signatures, and a notation editor for creating rhythms. Two synchronized metronomes support polyrhythms, and the app includes seven sound packs. Users can play audio files at custom tempos or switch to a fullscreen display with large visuals intended to be seen from a distance. Conductor mode combines the metronome and tuner. The tuner supports transposition for any instrument and custom tuning frequencies, and it can detect BPM from percussion through the microphone in real time. Chronal also provides an A4 reference tone with adjustable frequency. It is available through F-Droid and Google Play, with source code on GitHub. The listed F-Droid version requires Android 6.0 or newer and offers builds for four processor architectures. F-Droid lists audio-recording permission for microphone use while the app is in use; Google Play reports the developer declares no data collected or shared. The app is funded by donations.
