Will save several relationships ;) Although Telegram has it since long
Hate how everyone is trying to make conversations a temporary thing. Chat logs are a good reminder of things past, they shouldn't be deleted.
Sooner or later they gonna ruin that simple,fast and easy WhatsApp app by adding too much features as fb messenger app.
BlackBerry had that like 3-4 years ago... people frown at BlackBerry but they are a wonderful company that are victims of pop culture...
you know you've made a great app when everyone copies you, feel bad for snapchat
