Common questions
Is practice cents free?
Yes. The tuner, metronome, and HYKOM samples in the browser don’t need an account. The iPhone app is free too — Pro is only for the full HYKOM catalog, MM Mode, and custom meter maps.
Do I need to install an app to tune?
No. Open the tuner or metronome here. Safari or Chrome. If you want an icon, use Share → Add to Home Screen. The iPhone app is there when you want record and journal.
Can I use this as a guitar tuner?
Yes. It’s chromatic, so it hears any note — guitar and bass included. Open the tuner, allow the mic, play each string.
What is HYKOM?
How’s Your Knowledge of Music — theory and ear training for grades 6–12. Skills match contest types; every drill is original. Try samples here; full paths are Pro on iPhone.
