User interface

The only real complaint I have about this app is the user interface.

Look at WhatsApp, Telegram, Signal pretty much every messaging app has moved toward a more modern design style and adopted newer UI elements like Apple’s liquid glass design. There’s no way the developers don’t realise this app needs a refresh too.

What’s frustrating is that whenever anyone brings up the UI on their X profile, the comments just get ignored. The app works fine, but visually it feels outdated compared to almost every other messaging app now.
