iPhone
Your system, your space. Keep your everyday tools free and local, with optional plans for sharing with friends, cloud backups and moving to a new phone.
Many parts. One me.
Mosaic ME is a private, local-first space for plural systems to organize alters, keep track of fronting and co-fronting, write journal entries, and look back through activity over time.
Your system, organized your way
Create and manage alters with names, avatars and personal details. See who is fronting, record co-fronting, and keep a clear history of changes over time.
Journal and Activity
Keep personal journal entries alongside an Activity timeline that helps you see fronting history and other important events in your system.
Private by default
Your core Mosaic ME data is stored locally on your device. You do not need an account to use the core app, and your local system data is not automatically uploaded to the cloud.
Share only when you choose
Creating an account gives you access to optional Friends and Sharing features. Connect with people you trust and choose what information you want to share with them. There is no public feed and your system is not made public.
Your data stays yours
Mosaic ME includes local export and import, giving you a way to keep a copy of your data and move it when needed.
Built for the long term
Mosaic ME was created to be a stable, privacy-focused home for plural systems — not just another temporary platform. We intend to keep improving it while protecting the principles it was built around.
No ads. No public profiles of your system. No account required for the core experience.
Mosaic ME — Many parts. One me.
