Whisper your thoughts to the trees. A private, offline diary with no account required. Write freely, capture your memories, and keep your stories close. Tell the trees your secrets. Under Trees is a simple, private diary that lives on your device. Write about your day, capture your mood, add photos or a quick sketch, and keep it all behind a passcode — no account, no sign-up, just your journal on your device. Most journaling apps ask you to trust the cloud. Under Trees starts somewhere else: your journal content is kept in the app's private storage, protected by iOS. Nothing leaves your device unless you choose to back it up yourself. A DIARY THAT KEEPS UP WITH YOU • No account, no login — install and start writing right away • Works fully offline — on a plane, on the subway, anywhere • Fast, clean, distraction-free writing • Write as many entries as you want, whenever you want KEEP IT PRIVATE • Protect your diary with a passcode • Unlock quickly with Face ID or Touch ID • Auto-lock when the app goes to the background • Set up a security question to recover access if you forget your passcode — no reset email needed • Your data stays in private app storage, protected by iOS from other apps MAKE IT YOURS • Free themes, plus a theme builder with your own colors and backgrounds • Pick the app font that feels right • Entry templates to get you started: Traveling, Food, Self-care, Learning, Gratitude • Optional affirmations that greet you when you open the app MORE THAN JUST TEXT • Add photos from your photo library or camera • Draw a quick sketch right inside an entry • Use your voice with built-in speech-to-text FIND ANYTHING, FAST • Search by content or by tag • Browse your entries on a calendar • Stay organized with tags and a tag manager SEE HOW YOU'VE BEEN • A simple mood tracker built into the calendar • Mood insights to see how your mood shifts over 30 days, 3 months, or all time — even broken down by tag • "On this day" brings back memories from your past BACKUP & EXPORT, ON YOUR TERMS • Back up your diary and keep control of where your backup is stored • Restore your diary on another device • Export entries as .txt or PDF files to print or keep wherever you like GENTLE REMINDERS • Optional notifications to nudge you to write • Fully customizable and can be turned off at any time HONEST AND FAIR The core journaling experience is free because writing things down should be for everyone.
