5/5Great 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.

5/5Middle school parents REJOICE!!
This is possibly the best $.99 that I have ever spent. I have two children entering middle school next week, and I really did not want to spend the time in frustration teaching them how to use combination locks. Lo and behold this saintly man created this app. It is fun for kids and intuitive and super simple and 1000% helpful.

5/5So useful
This has helped me so much to learn codes . It also doesn’t have adds but you do need to pay for it but trust me it’s worth every penny. So just try it you won’t be sorry ! In two hours I learned how to open my locker clearly this is the best thing to buy on your on one!!!!😝🤪🥰If it could be ten stars it would be a 10 !!!

5/5Fun & 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! :)

5/5Good for starting middle school
It’s great for starting school especially with locker combinations and it really helps you get to customize the combination so it can be exactly yours, I like the color options, you can get creative. I also like how if you mess up it just restarts it doesn’t like give a “punishment” but yeah it’s a great app especially for starting middle-high school
