Start with an emoji. Save a moment from your day. EMMO is a mood journal where you can draw your own emojis. Pick a face, write a line, or add a photo to capture something you want to remember. A happy moment, a hard afternoon, or an ordinary day: there's room for all of it. • Make your diary feel like you Choose an emoji you love or draw your own. Mix fonts, backgrounds, and stickers to make each page your own. Write a whole story or leave just a few words about how you feel. It's up to you. • Keep the pictures and the sounds Add photos, videos, and voice recordings to your entries: a favorite meal, a view from a trip, or a few words worth keeping. Browse your diary's photos, videos, and audio together to revisit those moments. • See your days come together Use the mood calendar and charts to look back on how you've been feeling. Open an entry to remember what happened that day. Little by little, your notes become a record of your life that you can return to. • Find a starting point with Pal Once you have your own Pal companion, tap it while writing for a gentle prompt, such as "Was there anything today that made you stop and look a little longer?" Start with one small moment and write as much or as little as you like. • Choose what stays just for you Set entries so only you can view them. Add an app passcode and use Face ID or Touch ID on supported devices to help protect access to your personal journal. • More ways to keep your memories Sync your diary and attachments with EMMO Cloud. You can also export the text of your entries as a PDF to save separately or print as your own paper journal. There are handy little tools, too: add to-dos to your entries and check them off, view your records in widgets, and revisit the places you've written about on a map. Pick an emoji for today. Start with one line. Pal and cloud sync require you to sign in. Some features and cloud service options require payment. See the app for details.
