A journal that keeps up with you. Write an entry, tap a mood, tick off the swim, log the weight — DoThread holds all of it in threads you shape yourself. Free to start. No account, no one else's servers. WRITE PROPERLY Markdown where you want it: headings, lists, quotes, bold. Up to four photos in a single entry. Place and weather attach themselves, if you let them. LOG IN ONE TAP Home Screen and Lock Screen widgets record a mood or a check-in without opening the app. Put the Control Centre control on your Action Button and it is a single press. Ask Siri, or build it into a Shortcut. AN ENDLESS PAGE Canvas threads drop the timeline entirely: an endless page you write anywhere on, in handwriting-style fonts if you like. Photos, stickers and sticky notes drag, resize and rotate. Give the page a colour and a texture, and export all of it as one PDF. SIX KINDS OF THREAD Journals, mood trackers, daily check-ins, number trackers, checklists and freeform canvases. Pin the ones you live in to the top. Each with its own colour, its own moods if the standard ones don't fit, and Face ID on the private ones. SEE WHAT YOU'D MISS Two months of moods on one calendar. A streak you can watch grow. Numbers charted week by week. Search every word you have ever written, across every thread at once. YOURS, PROPERLY Everything syncs across your devices with iCloud, or to your own server over WebDAV if you would rather. Export to Markdown, or take a full backup you can restore. Nothing is locked in. DOTHREAD PRO One subscription unlocks everything: canvas threads, unlimited threads of every type, widgets, four photos per entry, analytics, custom moods, Face ID protection and WebDAV. A daily reminder, if you want one. Dark mode, Dynamic Type and VoiceOver throughout. Available in English, German, Spanish, French, Italian and Dutch. --- For technical assistance, reach our team at contact@chelodo.com Privacy Policy: https://chelodo.com/apps/dothread/privacy-policy Terms of Service: https://chelodo.com/apps/dothread/terms
