Ocean's Wave

Say it, then let it go. Ocean's Wave is end-to-end encrypted messaging and calling where every message โ voice, text, photos, files โ disappears on a timer you set. Most messaging apps promise privacy as a feature. Ocean's Wave makes it the default. Conversations stay between you and the person you're sending to โ nowhere else, for no longer than you choose. END-TO-END ENCRYPTED BY DEFAULT Every message is encrypted on your device before it leaves. The server stores encrypted data it cannot read. Only you and the recipient hold the keys. BURN TIMER FROM 1 MINUTE TO 3 MONTHS Set how long a message lives after the recipient opens it. When the timer expires, the message is cryptographically erased โ gone from both sides, unrecoverable. VOICE. TEXT. FILES. Send voice messages, text, photos, videos, and documents โ PDFs included. All encrypted. All ephemeral. ENCRYPTED VOICE CALLS Call any contact straight from a conversation. Calls are end-to-end encrypted the same way your messages are, and they connect your two devices directly wherever the network allows it. Nothing is recorded, nothing is stored, and nothing is left behind when you hang up. INVITE ANYONE Reach people who aren't on Ocean's Wave yet. Send an invite link, and when they join you're connected automatically โ no phone numbers, no contact uploads. ZERO-KNOWLEDGE ARCHITECTURE Your private keys never leave your device. Back them up with a 24-word recovery phrase only you control. Ocean's Wave cannot read your messages, recover your keys, or restore your conversations. This isn't a policy โ it's enforced by the cryptography. WHAT WE DON'T COLLECT - The contents of your messages - Your contact list - Your message history - Your encryption keys BUILT FOR PRIVATE CONVERSATIONS Journalists protecting sources. Teams sharing sensitive contracts. Anyone who believes private conversations should stay private. Download Ocean's Wave and have the conversations you want without leaving a trail.

Verdict
The clearest difference is update cadence: Ocean's Wave at every 3 weeks against Seifr's every 4 months. Seifr's advantage is iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
