Skype app is rly good app n close to my heart. as m living outside of my state I can daily do vdo chat with my family members and my frenzz.
a good quality vdo chat I can do by it. free vdo calls and normals calls also u can do.
any case u get dissconnected u can do text chat also.
sound quality is quite clear. m raly happy to get the app in my phone and in my laptop also. distance doesnt matter if u are using this app .go for it .
