Questions & Answers

Can I unblock apps before the session ends?

If you know your Screen Time passcode, you can bypass it — but LockHour Pro works best when you set a code you won't easily remember. The friction is the point.

What is the Pomodoro technique and does it work?

Pomodoro is a time management method: 25 minutes of focused work, 5 minutes of break, repeated. Research supports its effectiveness for sustained concentration. LockHour Pro is designed to complement this approach.

Does blocking apps drain the iPhone battery?

No. LockHour Pro uses iOS Screen Time, a built-in OS feature. It doesn't run any background processes that affect battery.

Can I block specific apps and leave others open?

Yes. You choose exactly which apps to block. You could block Instagram but leave Messages open, for example.
