Im impressed with Greta, but it's almost impossible to get anything workable out of it without spending more than 500 credits (for anything more than the simplest app). It can be frustrating losing credits on changes that have no effect and your going to need to fix alot of broken code sometimes. But the upside is it can only get better from here and the team seem responsive and helpful. Im going to stick with it. Please find a way to replenish credits lost by errors though, it's not fair at the moment. Thankss
