How do I install the Android app?
Download the APK and open it — Android will ask to allow installs from
unknown sources. Play Protect may warn too — choose Install anyway. If you
see “App not installed”, remove any previously installed copy and try again.
Requires Android 7.0 or newer.
How do I install the Windows version?
For the installer: Windows SmartScreen may show “Windows protected your
PC” — click More info, then Run anyway. For the portable ZIP: extract it,
then right-click the ZIP file, open Properties, tick Unblock and click OK
before running the app.
What do I get after buying PRO?
A personal page: PRO installers for Android, Windows and Linux, and an
“Activate PRO” button. Install the app first, then one tap on that button
unlocks PRO — it checks that the app is present. The key is shown on the
same page for manual entry on portable builds.
What is the difference between Base and PRO?
Base is the complete ball metronome — gesture tempo, up to twenty-four
balls, five rhythms and four voices. Free forever. PRO adds all twelve
rhythms, eight more voices, chords and the musical metronome (Maelzel
scale, tap tempo).
Does it work offline?
Yes. The metronome and all sounds live on the device. Only the one-time
license activation touches the network — after that, PRO runs without
internet.
