Messenger Lite is a slimmed down version of Messenger that offers the core features of Messenger for markets with slower than average internet speeds and a prevalence of basic Android smartphones.
Franz 2.0 is a desktop app that puts messaging services altogether in one place. It can combine apps like WhatsApp, Slack, Facebook Messenger, WeChat, HipChat, Skype and a lot more. You can even use multiple accounts for the Facebook Messenger - mix your business profiles and your private ones if you need to.
With version 4.7 for iOS, you can change what your Telegram looks like in the new Appearance settings. Choose between four different themes, including a minimalistic one (“Day”) and two dark themes (“Night” and “Night Blue”). The “Day” theme also allows you to pick an accent color for the entire app, like pink or purple.
