Pros:

• the UI is very clean and user-friendly
• great for deciding whether or not you should go to the doctor

Cons:

• while some people might think remote healthcare is the future, there are just way too many pitfalls - an app cannot replace a visit to the doctor
• diagnostics is a very complex field, you can't simply go to the internet and type: I have this and that ... It will most likely happen that it tells you you have cancer and only scare you
