I am using hike app it is same as whatsapp messenger .hike has very very awesome features as compare to whatsapp .its sticky features is awesome and one thing in hike is very very nice that is HIDE CHAT in this app we can hide chat which one we want to hide .in this app we can share moment with friend and also we can edit pic when uploading.i like this app more as compare to whatsapp but there is one problem where improvement is required that is security , this app is not end to end encrypted .so this app is less secure .audio and video calling is not better but good
