Hi @user2057, thanks a lot for your suggestion, and welcome to the Community Forum! 
I see your point, and I’m really sorry that our app is lacking doctor reviews sources at the moment 
Since we release new features one by one, it would be great to have a separate request for each idea. We already have a request for ZocDoc source and WebMD source - feel free to vote for them to get the updates 
Thanks a lot for your help, it’s truly appreciated!
