Agendula

Agendula

A modern Material 3 Expressive task app for Android. Reads, writes, and reminds — on top of an existing tasks provider, with no own sync stack.

Agendula is the task-list sibling to Calendula. Where Calendula is a pure front-end over Android's CalendarContract, Agendula is a pure front-end over the OpenTasks TaskContract provider — the store that DAVx5 (and SmoothSync, DecSync, …) syncs your CalDAV VTODO tasks into. No own database, no reinvented sync.

The name rhymes with its sibling on purpose: Agendula is agenda — Latin for “things to be done” — given Calendula's -ula ending. Calendula keeps your days; Agendula keeps your to-dos. (A Calendula flower head is botanically a cluster of many small florets — so the two apps are florets of one bloom.)

Status: data layer done, UI in progress. The full non-visual stack over the TaskContract provider — provider resolution, live-updating reads, writes, smart-list filtering, and a self-scheduled reminder engine — is built and unit-tested. The Material 3 Expressive screens are now being built on top, one at a time. See docs/ROADMAP.md for status, docs/ARCHITECTURE.md for how it's built, and docs/PLAN.md for the A-now-B-later design rationale.

Sync sources (by design)

Agendula works with anything that writes to the tasks provider — DAVx5 (CalDAV), SmoothSync, CalDAV-Sync, DecSync CC, or any Android sync adapter — because it builds on the provider, not on any one sync app. Google Tasks / Microsoft To Do are out of scope by design (proprietary; they would mean owning a sync stack). Open standards — CalDAV / iCalendar / DecSync — are the lane.
