Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.
WhatsApp for Desktop gives you the possibility to have all your messages in all your chats synchronized on your PC. And do not worry about security, every message is encrypted so only you and the recipient can read it, hear it or see it.
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.
