Remember it before it fades. Onemni is a private dream journal that shows what changes when something in your dreams returns. Record a dream by voice or write it down, and Onemni keeps your original before any analysis begins. CAPTURE FIRST - One tap to record. Audio is saved every two seconds, so an interruption can't take the dream with it. - Prefer to type? Write with no title, tags or form. - Remembered more later? Keep recording onto the same dream. - Your original text and every edit stay in version history. SEE WHAT CHANGES WHEN IT RETURNS - Onemni picks out the people, places, objects, animals, feelings, themes and events in your dreams. You confirm, remove or add them. - Compare dreams that include a detail with dreams that don't, against your own baseline. - Every comparison shows its sample sizes and opens the exact dreams behind it, counterexamples included. - With too little history, Onemni says "Not enough evidence yet" instead of inventing a pattern. - A report on your whole journal: streaks, lucid dreams, an activity heatmap, recurring details and mood. FIND ANY DREAM - Search by person, place or feeling, filter lucid dreams, or browse by calendar. - Save the searches you use most. PRIVATE BY DESIGN - No account, no ads, no analytics. - Your journal is encrypted on your device. - Lock it with Face ID or your passcode. - Speech recognition runs on your device. - Apple Intelligence tag suggestions and dream recaps run on your device, on supported models. - iCloud backup is end-to-end encrypted in your own iCloud account. You can turn it off, and voice recordings are included only if you choose. YOURS TO KEEP - Export to JSON, CSV or Markdown at any time, and import from JSON, CSV or plain text. - Password-protected backups, with audio if you choose. - Deleted dreams wait in Trash until you erase them. - One purchase: no subscription and no in-app purchases. BUILT FOR THE MOMENT YOU WAKE - A morning reminder at the time you choose. - Siri, Shortcuts, the Action Button, Control Center and Home Screen quick actions open Onemni straight to recording or writing. - Works offline, and follows your text size and light or dark appearance. WHAT ONEMNI IS NOT Onemni doesn't interpret dreams or tell you what they mean. It shows what your own history says, with the evidence to check it. Requires iOS 26 or iPadOS 26 or later. Apple Intelligence features need a compatible device with Apple Intelligence turned on.
