01 / Overview

Your life. One system.

A connected day

Today brings tasks, agenda, and habits together. Tasks support subtasks, dependencies, and three progress states.

Projects and notes

Projects with tasks, milestones, and linked notes. Markdown writing with a preview and connection map.

Phone and tablet

Adaptive Compose interface and a local Room database. Focus and finance are available as additional tools.

02 / The problem

Planning a day requires connecting tasks, agenda, projects, notes, and habits.

03 / The approach

A connected workflow.

A shared local database connects the modules through a native phone and tablet interface.

Intercambio / Release 0.1.2

Notes as stations. Categories as routes.

The new identity connects violet, lavender, and mint routes at a shared station. Version 0.1.2 applies it to launcher icons, tablet navigation, and settings. The installable release is a signed development APK; the unsigned release APK is for build inspection.

05 / Product decisions

Built with intention.

A shared local source connects the modules without requiring an account for local productivity. Version 0.1.2 introduces the Intercambio identity across icons, tablet navigation, and settings.

Behind the interface.

Kotlin / Jetpack Compose / Room / Android 9+

Development version. Drive and Health Connect are optional and require configuration; real cross-device synchronization and real health records still need verification. Some advanced features remain partial.
