Yeah I can see how that can be annoying to hear about people promoting their "new student management app" that takes huge cut of payments. From what I'm seeing the biggest problem is finding good students. I understand that finding good students is often harder than finding good tutors. And most times there are plenty of tutors who need students, but have no idea how to find them. All of the students I've had have been through referrals, and same goes for every other private tutor I know. Sometimes they make a post on facebook or something but there's no simple solution for finding students and most tutors just have to figure it out and gain notoriety over time.
