Ratings and reviews

Would be nice to have the option to customize/change colors of receive/sent messages. So far, acquainting myself with the app. Another thing that would be helpful is to be able to short press (versus long press) on either an avatar or chat message within the main screen list and delete chats that way. Also, swipe left/right on a chat message to either call that contact; delete, mark as read (or unread) a message. Hopefully these features or at least a few of them can be implemented??

Wonderful App! Delta Chat is an amazing and secure messaging app — I really love how it works. Everything runs smoothly and it’s fast and reliable. I just wish the developers could enable voice and video calls to make it even better. That would make Delta Chat perfect!

📧🛡️💬 Delta Chat is like email in a superhero costume 🦸‍♂️—uses your existing inbox, but chats like a messenger 📲. I like how it skips central servers 🗑️, encrypts everything 🔐, and still feels snappy ⚡. It’s perfect for privacy lovers 🕶️ who want control without the setup drama 🎭. No account creation, no metadata leaks, just pure decentralized messaging magic ✨📡🧠. Great for rebels, nerds, and anyone who wants to turn email into a chat app 💥📨🧬.
