How do I unlock Pro?

Open Settings → Unlock Pro. You can buy Strumlux Pro once (no subscription), restore a previous purchase, or watch a single ad to unlock everything free for 24 hours.

Do I need an account?

No. Strumlux has no sign-up and works completely offline. Your progress is stored on your device.

The sound seems off / I want tighter timing

Make sure your device isn’t in silent/low-power mode and that Strumlux is updated to the latest version. If a problem persists, email us with your device model.

I bought Pro but it’s locked on a new device

Open Settings → Unlock Pro → Restore purchases while signed into the same App Store / Google Play account you used to buy it.
