App is great, only problem is that there is no serbian language, i mean it has croatian, but still it is not 100% same, i would recommend using it but not cheating off of it because when I did do that my teacher said I had chosen the long/hard way of doing it. 15/10 a must have No ads btw.
This app doesn't just give you the answers it explains how to get that answer for yourself, there are so many more answers than it's competitors, it also helps u solve the problem and goes over how to do it. Good explanation. I totally recomend.
The person that made and came up with this idea is an angel. Even so, it is still an extremely useful and convenient app that shall continue to use in the future. This app is too good. Great to see apps like this are coming up, best app according to me and the scanner feature is best and working very well.
