Good app but definitely needs alot of optimizations.... One (as there's a few more bad things that happens) of the worst things that happen if sometime I open another app or go to the calculator for 2 sec and when I come but to the app all the lines with numbers changes to black where you can't see any texts or number unless you fully close the app and reopen it...I wish I can attach pictures to show what I'm talking about 🤦‍♂️
