Hello.

There is not such thing that you need have a degree to become a app developer. You can become app developer by sitting in Home and getting certified by nptel or such things.

Preferred to gain a BTech degree and do what ever you are interested in simultaneously with degree.

Hope this is helpful.

Good luck.

Hello, for app development you need to do either BCA and then McA in Computer application or B.E/B.Tech in Computer Science and Engineering or Information Technology after 12th PCM. After choosing this learn Android or iOS for app development this will help you to achieca your goal.
