A lighter way to write. A richer way to return.
DiaryThreads connects quick daily writing with the context that makes a private journal more valuable over time.
Updated August 25, 2026

What can DiaryThreads do?
DiaryThreads lets you write short private entries, continue them with replies, quote older memories, search and browse by date, favorite what matters, review on-device insights, use Home Screen widgets, sync eligible diary data through private iCloud, import older writing, and export selected memories or the whole diary.
Capture without turning every day into an essay
A new entry can be a sentence, an observation, a to-do list, a photograph, or a voice recording. Version 1.1 can autosave meaningful new entries, replies, quotes, and content shared from other apps as local drafts.
Each entry supports up to nine photos or Live Photos, one video, or one voice recording. Optional location and State of Mind can add context when the writer chooses them.
Return with the right amount of context
Search and the calendar help when you know what you want. Replies, quotes, the rediscovery feed, and Premium Your Trends help when you only know that an older thought matters again.
Home, Search, Analytics, and Premium Favorites form the four main destinations. The product keeps every path inside one private diary, with no followers, public profiles, likes, ads, or public discovery.
Version 1.1 brings emotion insights to every recorded moment
An on-device algorithm can suggest a nearby emotion while an entry is being composed. The suggestion changes nothing until the writer opens the State of Mind picker and confirms a value.
Emotion Trajectory uses only explicitly saved State of Mind values. Version 1.1 also makes DiaryThreads available on iPad and Mac with optional Premium private iCloud continuity.
Choose what leaves the diary
Premium unlocks ordinary entries beyond the free 140-character allowance, file attachments, handwriting, every Topic, unlimited current entries, favorites, share posters, Your Trends, Thread Growth, three Home Screen widgets, private iCloud sync, and local-only Beta import and export. Free users can keep up to 30 current entries and write long-form Articles.
Import supports common documents, structured data, PDFs, and selected social archive exports without signing into those services. The Share Extension can hand text, a link, or up to nine images to the local draft inbox. Export creates a photo-aware DOCX or Markdown ZIP. Sharing and file export begin only after the diary owner chooses them.
