This is an advice and it's okay if you don't want to since I can do this myself. Highly reccomend, never seen such a useful math app. Many gifts on the way for the hard work, this app is the only free app that does anything like this, and especially with how fast and accurate the results are.
Wich i understand, you have to make a living but it kind of takes the whole purpose put of the app. The best offline math app ever. Unlike the typical ones. This is a great app for studying and has multiple great features, very good cost compared to the other app which didn't help me.
I would always look up calculators for things and often use the browser version of this but this is so much more convenient and it's amazing expessially since you can take pictures and unlike other picture apps it's not like you just get 3 pics then have to pay ton of money for more.
