Why do all of these learning apps cost money – TinyTap: Kids' Learning Games Review

Would be nice to have free portion of the app without being obligated or asked to sign up for a free trial. Maybe split it into basic and premium. I just wanted to test it out first with my child without signing up for a trial. Then forgetting about it and getting charged. I’ll be uninstalling.
