This is first-party material published by Lumi Studio, the developer of every listed app. I built LockHour Pro: Block Apps, so read this as the developer's own explanation, not a third-party review.
The problem
App Blocker & Focus Timer.
How it works
During exams, willpower isn't the tool — a hard timed block is — LockHour Pro is built for this.
Block the apps that steal your time — and get your focus back.
What the app actually does
Everything below comes from the app's own App Store listing — no more, no less:
- Pay once
- No ads
- On-device
- Private or on-device processing
Pricing
It is free to download, with a one-time purchase that unlocks the full version. The App Store listing labels it: “Free to start · one-time unlock”.
Honest disclosure
The artwork in my apps is AI-generated and the speech is system text-to-speech. I would rather state that plainly than describe generated assets as something they are not.
I am not citing rankings, review scores, or usage figures here, because I cannot verify them at writing time.
Where to get it
LockHour Pro: Block Apps is on the App Store: https://apps.apple.com/us/app/id6780107485?pt=118326163&ct=devto&mt=8
