MyBrain
An Android productivity app combining tasks, markdown notes, calendar events, daily mood tracking, and on-device AI.
Manage tasks, markdown notes, calendar events, and mood logs alongside an AI agent with encrypted local sync.
MyBrain is an Android productivity hub designed for professionals who need an integrated task, note, and schedule manager. It includes an on-device AI assistant capable of creating and retrieving items without sending personal data to remote tracking servers. If you want a private organization app with local multi-device sync, this fits your workflow.
What it is
MyBrain consolidates daily organization into a single dashboard featuring structured task lists, markdown notes, calendar views, and a mood diary. It incorporates Google ML Kit GenAI for on-device AI chat and automated item creation while keeping your data local. The app also allows you to pair devices on your local network using QR codes for encrypted peer-to-peer data transfers.
Who it's for
This tool suits privacy-focused Android users and executive assistants who want a single personal management app with native AI tools. It does not suit teams requiring central cloud collaboration or non-Android mobile users, as current builds target Android.

FAQ
Why is MyBrain no longer available on F-Droid?
F-Droid builds were discontinued because recent updates rely on Google ML Kit and native dependencies that violate F-Droid inclusion policies.
How does device synchronization work without a server?
MyBrain uses Network Service Discovery and embedded Ktor WebSockets to pair devices over your local network and exchange encrypted payloads directly.
