Great for practice

When I was learning how to unlock a lock, it was very confusing and frustrating so I decided to download an app to help me learn and practice. After practicing a while with this app, I got the hang of it. When I had to unlock it in real life, I was successful in doing so. There are many great features. It’s wonderful that you have the ability to change the color of the lock and the type of lock (39/49) to accommodate what you are going to learn. It’s great that you’re able to randomize the combination and can use the walkthrough provided or solve it by memory. All great features which contribute to how helpful this app is. However, there is some minor ways the app can be improved. It doesn’t have to be implemented because the app is good and works but certain features would be nice or helpful. Clarification that locks usually need to be reset (especially if it is a school one that others have used) would be incredibly useful. By this, it would tell you to pass 0 twice/trice before starting to go to the first number. A feature that could be convenient is for the lock to go back to 0 when you mess up. Although I am not fully sure about this option because when using a real lock, it doesn’t work like so. But, adding it in the walkthrough or explaining how to reset it somewhere in the app would be great for new users. A final suggestion I have is to add a sound when it unlocks. I am sure people will love feeling a sense of reward from the app and will continue to practice.

Awesome app

Such a nice app for to play with even if you are bored and have nothing to do the only thing I want so bad on this app Is sound so when every-time you unlock the lock it will make a sound also please add a option where everytime you unlock the lock it will randomize the lock every time this can be both options for like a setting one can be Lock sound and other for Randomize number every-time you finish the lock I hope this gets added as a feature thanks Edit: when is this update going to be pushed out for the public like is it still in development for the new suggestion or has it to be another few months for it to be finished with for the new update. Second Edit: Thanks for implementing that randomization for every time it gets completed, is there a way you can make it an option in the settings or will that be hard to implement because everytime you complete the lock you have to click randomize yourself do you know what I mean by making it option it will make it kinda easier to randomize.

Fun & Effective!

This app is absolutely perfect for my twins! They’re both about to go to middle school, which means they’re going to have lockers soon. Considering that they are on their phones all the time, I thought an app would be perfect for their learning. This app is particularly useful because the interface is extremely easy to understand, and the twins also enjoy cracking the codes. Would definitely recommend! :)
