Plural Star is a private, offline-first system management app built for plural individuals, those with DID, OSDD, or any form of plurality.

Made in part with AI assistance, which is one of the main reasons we went Open Source. So that anyone wishing to, or with concerns, can examine the code.

Simply Plural and Octocon are being discontinued. Plural Star is the replacement you own entirely; your data stays on your device.
Features

Three-Tier Front Tracking
Track Primary Front, Co-Front, and Co-Conscious. Each tier has its own member, mood, note, and energy level (1–10); Primary also tracks location. Members are exclusive to one tier. Set all three from a single modal with a searchable picker. A persistent notification keeps all tiers visible. Optional front-check reminders at 1, 2, 4, 8, 12, or 24-hour intervals.

Member Profiles
Profile pictures, 900×300 banners, names, pronouns, roles, colors, rich-text bios. Full Markdown editor. Freeform tags and colored named groups; members can belong to multiple groups. Filter by group, tag, or search. Sort six ways: alphabetical, reverse, age, color, role, or manual. Tier badges (Primary, Co-Front, Co-Con) display when fronting. Archive dormant members: history preserved, restorable anytime.

Observatory Mode
Observatory Mode turns Plural Star into a Manual Status Tracker and Journaling App, with a rebuilt UI for the Singlets in our lives, while granting them access to almost all the App's features. Ideal for non-plural friends, family, and caretakers.

Custom Fields
Define your own per-member fields. Types: text, number, toggle, date, month/year, month, year, Markdown. Reorderable, renameable, exportable. Imports from Simply Plural custom fields.

Per-Member Noteboards
Each member has a noteboard, a shared space where any headmate can leave notes for or about them.

System Polls
Polls the whole system can vote on. Vote tallies, voter tracking, optional closure. One vote per active member; changeable until closed.

System Map
Chart the relationships between your headmates on an interactive force-directed graph. Start with an empty canvas and place members deliberately, or let them join automatically as you create relationships.

History & Insights
Front History: timestamped log of every switch, organized by day, with co-front and co-conscious tiers inline. Member History: every session, mood/location/note change, energy level, and authored journal entry per headmate, plus totals (time fronted, sessions, top mood, top location). Add retroactive entries with three-tier support and overlap detection.

System Statistics
Total fronting time, session count, and message count with time-range filtering. Expandable leaderboards (top 5 up to 25) for fronters, co-fronters, co-conscious, chatters, moods, and locations. Peak Hours chart shows when your system is most active.

System Chat
Local-only IRC-style chat. Up to 100 channels, renameable and reorderable. Speaker is independent of who's fronting; chat doesn't affect front or history. Text, image sharing, replies, emoji reactions. Archive channels to free storage.

System Journal
The same rich-text entries with full Markdown as in member profiles. Tag entries by author and topic hashtag. Optionally lock individual entries or the whole journal behind passwords.

Import & Export
Import full system data from Simply Plural, PluralKit, Octocon, Ampersand, Ourcana, HiveMind, & PluralSpace. Export as .zip, HTML, or email summary, with per-category toggles for what to include. Import .txt, .md, or .json files directly as journal entries.

Medical
Medication reminders, appointments, medical history, and emergency info in one Hub tile — available in both system and Observatory modes.

Multilingual
17 languages: English, Español, Français, Deutsch, Português, Suomi, Norsk, Italiano, Türkçe, Bahasa Melayu, Tiếng Việt, ไทย, 简体中文, 繁體中文, 日本語, Русский, and Українська. Auto-detects on first launch.
