iPhone. Write in the moment.
Capture text, photos, or a voice recording, then reply when a thought continues. Home, Search, Analytics, and Interactions keep writing and revisiting close together; Favorites opens separately from Home. People and Topics share Interactions.
Send text, a link, or up to nine images to local drafts through the Share Extension. Premium widgets offer writing and memory shortcuts. Navigation fits the available screen, including supported iPhone Duo layouts.
iPad. Give a thought room.
Browse the timeline beside an entry when space allows. Split View, Stage Manager, keyboard, and pointer support fit the diary around your day, with widgets, the Share Extension, and existing deep links close by.
Add Premium handwriting with Apple Pencil or a finger. iPad also works on its own with a local diary.
Mac. Continue at your desk.
Browse Home, discovery, Search, Calendar, Analytics, Favorites, Drafts, and thread details in a native multi-column library. Writing, import, export, share posters, Premium, and Settings have their own native windows.
The optional menu-bar editor keeps paragraphs, to-dos, photos, video, voice recordings, location, replies, quotes, edits, and local drafts close while you work.

Sync when you choose.
Start locally on every platform. With verified Premium, enable private iCloud sync through your Apple Account. Transfers need an internet connection and available iCloud access; each device keeps its local diary.
State of Mind and Apple Health access stay on iPhone and iPad. Mac has no HealthKit access and does not read or display Apple Health emotion values. Home Screen widgets are available on iPhone and iPad.
A few things worth knowing
Do I need a DiaryThreads account to use more than one device?
DiaryThreads has no app account. Optional private iCloud sync uses the Apple Account already signed in on each device and requires verified Premium.
Can I use DiaryThreads on iPad without an iPhone?
Yes. The iPad app can keep a local diary of its own. Private iCloud sync is optional.
Does the Mac app read Apple Health emotions?
Apple Health State of Mind features stay on iPhone and iPad. Mac has no HealthKit access.
