How to buy
- Open Kaizen Timer.
- Tap Upgrade on the nag banner, or go to Settings → Upgrade.
- Tap Buy Pro — $4.99.
- Google Play's standard purchase flow appears. Confirm with your PIN / biometric.
- Pro activates immediately. The nag banner disappears; you can now set sessions up to 23 hours.
After purchase
Your purchase is tied to your Google account. You can:
- Install Kaizen Timer on another device with the same Google account — Pro activates automatically.
- Change phones — as long as you sign into the same Google account on the new phone, Pro follows you.
- Uninstall and reinstall — Pro activates again on first launch.
