An iOS diary you’ll actually want to open.

Beautifully designed. Mathematically secured with AES-128. Completely yours.

Vault-level protection, not a simple lock.

Your words are never stored as plain text. Not your entries. Not your photos. Everything is secured with local AES-128 encryption on your device, and decrypted only while you read it.

Zero-Knowledge Architecture

Your encryption key never leaves your phone. We cannot read your diary, even on our servers. True end-to-end privacy.

Maximum Security Mode

The moment you leave the app, the key is wiped from memory. Your diary is unreadable even on an unlocked phone, even if extracted directly. Hardware-bound and unlocked only via Face ID.

WispDay reflection feature allowing users to reply to old journal entries

Reply to your own thoughts.

Entries don't have to be static. Revisit past days and add reflections. Watch your perspective evolve over time within the same private thread.

strictly on your terms.

Coming Soon

Verifiable Privacy.

Don't take our word for it. We're preparing to open-source WispDay's encryption core — the code that handles your keys and encrypts your entries — so security professionals can review and improve it. Transparency is how privacy should work.
