Locker: Combo Lock Practice
Open your locker confidently
Free · Designed for iPad. Not verified for macOS.
Practice your locker combination before the first day. Real dial, real rules.
New locker? Practice opening it before you have to do it in a crowded hallway.
Locker is a realistic combination lock you turn with your finger. Enter your own combination, spin the dial, pull the shackle. When something goes wrong, Locker tells you exactly what happened in plain words — "You went past your second number" — instead of just resetting.
EVERYTHING IS FREE
• Your own combination, saved only on your phone
• Dials numbered 0–29, 0–39, and 0–49
• Teach Me walkthrough with right/left arrows on the dial
• Clear explanations for every mistake
• Realistic dial feel with a sensitivity setting
• Clicks and haptics you can turn off
• Six dial colors, light and dark mode
WORKS FOR ANY LOCKER
School lockers, gym lockers, work lockers, college dorms. If it has a dial, you can practice it here.
PRIVACY
No accounts. No ads. No tracking. Your combination never leaves your device.
Ratings & Reviews
Easier first try:
• Teach Me now sits above the dial, so you can see and turn the dial while you read each step.
• When the lock says Open, pulling down anywhere on the lock opens it.
• Practice this lock works right after you type your combination. No need to save first.
