Hey guys this is vicky you friend I am again came with a studying apps review named byju. Byjus app is a nice designed and smart working app it provides a better course selection choice it provides best theory and virtual practicals. but it have some faults like not have any option to choose video quality it takes a large quantity of users mobile data but insted of it its videos do not plays after loading the video when data is off but if you have a unlimited pack or have a cheap data pack. than its a thumbs-up for this app from me so guys if you like my review than like comment share and follow my account. thanks
