Zocdoc is an amazing app in terms of finding docs:
1. Type where I get hurt;
2. Type my zip code,;
3. Choose my insurance plan；
4. Find a doctor around;
5. Select a time slot;
6. And confirm.
Total two minutes. Just this damn easy. It couldn't be harder to go to hospital in both US and China. But this is mind blowing user experience. I can't stop praising them, cause my previous hospital experiences were like hell.
Well, not too surprise, who back them?
