oChat is a messenger you can walk into. Sign in with Apple or Google in one tap — no phone number, no SMS code, no password to make up — and you are writing. The same account works on iPhone and on Mac. Your one-to-one chats and groups are end-to-end encrypted with Apple's own CryptoKit. Keys are set up on that first sign-in, so there is nothing to switch on. AND YOU CAN CHECK IT In a one-to-one chat, compare a fingerprint face to face — eight pictures, a 60-digit number, or the QR code you show each other — and the chat is marked verified. If that key changes later, a warning appears above the message field. Chats with our support team are not end-to-end encrypted, and the app says so on that screen. INSIDE • Chats and groups, with invite links you can revoke one by one. New members can get recent history from the person who added them. • Replies, edits, reactions, pinned messages, an archive and notes to yourself. • Photos, video, files, voice messages and video notes, encrypted on your device before they are uploaded. • A chat list that opens with no connection; an unsent message waits in the outbox and goes on its own. • Your chat history lives on your device. Our server holds a message only until your devices receive it, 30 days at most, and there are no cloud backups. To move to a new iPhone or Mac, enter a 6-digit code on your old one and your history comes straight across. • Notifications with no text in them: the push preview is encrypted, and our server cannot read it. • Privacy settings that work both ways, a Devices screen that closes any other session, plus reports, blocks and moderation labels. • 47 languages, a dark theme, links that open inside the app. PLANS Messaging, groups, encryption and opening any media sent to you are free. Premium is a monthly subscription. It adds sending media — photos, video, files, voice messages and video notes — and what else it includes is shown on the subscription screen in the app. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.

Verdict
The clearest difference is in-app purchases: dimsa at none against oChat's 10. dimsa also leads on iOS requirement (14.0 vs 18.0). oChat's advantage is update cadence (every 6 days vs fortnightly) and ratings volume (7 vs 1). On price, rating, ads and device support there is nothing between them.
