Comments on MathLock for Android

★★★★★ Llybi Setga · Jul 1, 2026

I think I may have discovered my live for math through this app, but I would have loved to be able to randomize &/ customize the workload. It's sometimes fun to have one or two question at work, but I would love to have at least 4 when I wake work just so I don't find myself doom scrolling after the difficult or easy one question.

This is exactly what I've been looking for, for a LONG time. This is literally the best thing if you have problems with procrastination. I've been addicted to my phone since as long as I remember, and it's been having really negative impacts on my life no matter how much I wanted to ignore it, also my math isn't the best, so this is perfect! Now I can actively DECIDE if I want to use an app instead of just clicking on it and getting stuck for hours, AND practice math! :)
