Awesome stickers with very good custom sticker support.
You can use a nickname to chat, you don't need to share your GSM number with anyone which was an incredibly stupid idea in the first place. On that account , better privacy than Signal or ShitsApp.
You can use simultaneously on multiple web AND mobile devices.
You don't lose your chat history when you login from another mobile device like in ShitsApp.
Stores your media server-side. So you always have your full chat with all the media in it. Of course this requires care about what you share with other.
Forwarding messages between chats has a lot of flexibility.
Message editing. Which ShitsApp finally copied. 🤣
Constantly improved. They are always adding more features.
