This helped a lot. I'm starting middle school and I couldn't get the lock open at the orientation but now I feel better. This app shows u how to open the lock and u can set ur own combination any time and change it anytime. If ur having trouble it shows u how to do it and u can go to options and change the type of lock and change how many numbers u want on it, u can even change what direction u wanna go first. Best app. Thx

This app assists greatly in helping one master opening one's lock! It is definitely worth the price. My only wish is that we could change the color of the lock and locker; because it would be nice, especially for students, if the color of the app's lock/locker matched that of their real lock.

I practiced on this and then the first time I went to open my locker, it worked! I've gotten it open almost every time,once I forgot the combo and sometimes I just pass the number. Then my friend was having troubles with her locker and she practiced on it and now she can open her locker too! A really great app!👍🏻👌🏻👍🏻👌🏻

Banish your combination lock anxiety forever with Combo Lock 101, your portable combination lock simulator. Now you can practice dialing those pesky combination locks in your life whenever you feel the


Once you've set up your lock simulation with a combination, you can simply dial away, see an automated dialing demonstration, or even get an x-ray view of your lock's internal components.

Combo Lock 101 includes separate simulation models for padlocks, lockers and safes, each based on the physics of real-world lock mechanisms. With a complete array of configuration options, Combo Lock 101 is sure to have your lock covered.

Note that this app does not store your combinations between launches. This could be insecure. Combo Lock 101 will help you learn a combination through practice and repetition, but it will not simply remember it for you.

* You can change the lock / locker style and combination range by tapping the "i" button on the toolbar.
* The automatic dialing demonstration is set up to open any possible combination lock and may seem different than the technique you've been given (if it's something like "at least two turns to A, back past A to B, then back to C"). These are actually exactly the same dialing sequences.
* Thanks, and have a great school year!
