Well, probably not. OP said they make half their monthly salary from it. That site makes $300. Maybe OP is in a poorer country and makes $600 as a software engineer, and uses a Mac. They did post about it three years ago, so it seems linked to them. But I'd wait for OP to confirm: the person posting is not OP and may just be guessing based on OP's post history and having searched 1k projects.
