I am a backend software developer with a few years of experience and doing considerably well, I will like to take my career up a bit I'm considering venturing further into mobile app development or data science. I'll cherish advise from nairalander who has been in one or both fields, I have taken some courses in flutter for mobile and also python for data scraping but I'm still confused and at a cross-road

Data science or mobile app development which will you advise a brother to go into considering ease of finding help, job and future prospect
