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.

Numbers charted week by week. Search every word you have ever written, across every thread at once.
