Ourcana ("Our Arcana") is a Plural System tracker app for managing a collection of members (which can be alters, original characters, personalities, etc). Track your system members, which of them are fronting (if any, or even all of them!), and use markdown to log journals, design rich profiles (with formatting, style elements, and inline media) and track relationships and interactions between all your system's members. Import from SimplyPlural, import and sync data (or active members) with PluralKit, or manage all your data entirely offline with exported copies of your whole "deck"! Ourcana has been tested with up to 20 thousand members. Ourcana's design and UX allude to classic card decks, fantasy fortune-telling, and medieval alchemy and magic with the "Tarot" and its "Major Arcana" cards as a for-fun, lighthearted theme to manage character, system, member, and group data. One can change all the terms inside the app however they'd like in settings such as "deck, "member", "system", "fronting", etc. Color highlights, accents, light and dark mode, and more are all customizable in-app with a rich UI. PluralKit and SimplyPlural color settings transfer automatically! Import from SimplyPlural, import and sync data (or active members) with PluralKit, or manage all your data entirely offline with exported copies of your whole "deck"! PluralKit synchronization is a first-class feature, with sufficient functionality to completely replace the PK dashboard down the line. Deeper PluralKit-specific integration features will launch with our 1.0.0 online update, so stay tuned! This application is made with accessibility and ergonomics in mind. I've developed it for my own online community first and many others adjacent to it all over the net known as the "plural" community. As a journal and personal tracking app, Ourcana keeps all your data private, personal, and offline-first by design. Journals are only stored on the device itself, and the sync settings allow one to choose which other data (if any) to share with PluralKit. Ourcana is priced at $1 USD (or regional) to support the development team, but can be found for free, forever through our community resources. You can try the web app at https://ourcana.space/ before getting the app! Transfer data between devices with the import/export feature. Our End-User License Agreement for Ourcana Online is the same as Apple's default and can be found at the link below. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Sheaf is a plurality tracker for plural systems. Create member profiles, track switches, keep journals, send notifications of front changes to others, and more. Built by plural systems, for plural systems. Inclusive of all plural experiences regardless of origin or framing - no required diagnosis, no gatekeeping, no assumptions about how your system "should" work. Designed to be privacy-first and keep the user in control. Sheaf also includes Apple Watch support with a flexible set of complications and widgets that allows you to see your front status at a glance, register switches, and view history all without ever pulling out your phone. Sheaf exists because Simply Plural is shutting down, and the plural community needs somewhere that won't quietly disappear. Sheaf is open source under AGPL: the code is public, the project can be forked, and you can self-host your own instance if you'd rather keep your data on your own infrastructure. Sheaf can import your existing system data from Simply Plural, with support for more tools coming soon. What you can do: - Track system members and front changes - Write member- and system-wide journals - Manage member groups - Send notifications of front changes - Use the hosted service or run your own - Cross-platform: Mobile, wearable, and web clients We're rolling out in stages. Sensitive community data deserves slow-and-correct over fast-and-sorry, so the hosted service is moving carefully through preview before a full public launch.

Verdict
The clearest difference is price: Sheaf at Free against Ourcana's $0.99. Sheaf also leads on in-app purchases (none vs 2) and review sentiment (100% vs 71%). Ourcana's advantage is ratings volume (41 vs 3) and chart position (#19 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.
