What is difference between telegram z vs telegram k ?
According to a lifehacker -" The two web app versions
only really differ in their visuals: Version K has a
slightly wider chat screen, its menus are a smidge more compact,
and its icons have a more 3D “buttony” design; while Version Z's
icons are flatter and its color palette is more desaturated in comparison."
Telegram vs Whatsapp
Users can send any kind of file through Telegram. WhatsApp limits video, images & document type files which is very difficult for a good number of users. Users on telegram can log in on multiple devices at the same time and able to receive messages on all devices.
They can remember their sessions on even browsers too.
