User Reviews

Delta Chat is praised for its privacy-first approach, simplicity, and usefulness for basic messaging, including groups and channels. Positive feedback highlights reliable everyday use and a clean UI. However, multiple reviews point to recurring problems with notifications, onboarding/login friction, and a cumbersome encryption/verification process that hampers casual use.

Pros

Privacy-focused design with strong protection for user data.
Practical, simple, safe, and pleasant user experience with a clean interface.
Generally reliable for everyday messaging and international use.
Supports creating groups and channels for organization and discussion.

Cons

Notification issues: sounds not playing and messages not delivering reliably, with inconsistent alerts.
Login/signup friction, including slow signup and trouble logging in with Gmail/Office 365.
Cumbersome encryption/verification flow that adds hoops to use encrypted chats (e.g., QR codes).

Recent reviews

I love using Delta Chat: the ease of setting it up, the fun variety of apps that let you share notes, todo lists, games, or photo diaries with a contact or group. It’s so handy to have simple secure shared tools in this format. I’m still working on bringing over contacts though, that’s the hard part.
