I built a medical tracking App for a friend undergoing cancer treatment. He uses it to record side effects, medications, temperature, blood pressure, and more. The app turns his records into charts, making doctor visits much more efficient. Most importantly, all data stays on his own phone, giving him complete peace of mind!!! We can build apps not only for ourselfs but also as a new type of gift for people we care about. I am excited about this as I have no IT background. NiuNiu keeps its promise that it is easy to build and deploy a real app just by chatting. definately I will try more ideas.
