I'd like to know what the best way(s) to make money with mobile development.
Some devs have already told me that it'd be making building mobile apps to prospect customers.
As a second option I think I can try to build a very useful app as a startup and hard working in marketing that one. For instance, I'm enjoying to study Android development but I have doubt about how make real good money as freelancer in mobile development field.
As a third option I think after of getting some real skillset for instance in Android development to try to produce some course on Udemy thinking that as a freelancer activity too.
I'd listen to your advices about my issue. So far I wish to work strictly informal (no contracts).
Thanks in advance!
