Well honestly @ziixoyn it's a very interesting topic for discussion - I work all day long with my iPhone, i have FB and Insta as Apps and they work great!
I have just now downloaded Esteem for my phone, until now I was dealing with the website from my phone. I have to say I find the app very good. It still needs to be more user friendly for technophobes like me and slightly easier to navigate, search etc but I really like the concept behind esteem And do believe it has a very bright future if they keep developing their mobile App.
