Ratings and reviews

Amazing app to teach kids how to use combination locks. You never thought you would need an app like this until you have to teach kids how to use combination locks. Best of all you can teach them with the actual combination that they use. Great developer as well.

Great app for youngsters to get accustomed with combo locks. Clean design with directions the update real time. Haptic feedback is a nice touch! One suggestion would be to include visual cues for dial direction

my lock at school was easier then this🫩 wasnt even like this

What’s new

School is here. So is your locker. This update brings a smoother dial, a polished loading screen that matches your color theme, and performance improvements under the hood. First locker or fiftieth, you're ready.
