Phase 0 of docs/OWN-STORE.md. Prepares the seam for the Room store while the provider is still the store. Task.id (the materialised instance row id) is gone; Task carries occurrenceStart, its RECURRENCE-ID anchor, instead. updateInstance takes (taskId, occurrenceStart, form) and AndroidTasksDataSource maps that back to an instance row itself, so the provider path exercises the new signature before Room exists. Lazy-list keys move to Task.occurrenceKey. Two occurrences of one series can appear in the same list once expansion is ours, and taskId alone would collide there. domain/Models.kt stops importing TasksContract — status, priority and local-account constants now live in domain. StorageMode gains OWN as a third value; LOCAL keeps meaning the dmfs provider until it is deleted. Room 2.8.4 and room.schemaLocation added to the build.
Agendula
A modern Material 3 Expressive task app for Android.
Keeps your tasks on your device, or on top of a tasks provider you already use.
Open standards, no account required.
Agendula is the task-list sibling to Calendula.
Where Calendula is a pure front-end over Android's CalendarContract, Agendula
speaks the dmfs TaskContract — the same shape DAVx5 (and SmoothSync,
DecSync, …) syncs your CalDAV VTODO tasks into.
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.)
Where your tasks live — your choice
| Where | Sync | Needs | |
|---|---|---|---|
| On your device (default) | Agendula's own task store, bundled in the app | none yet — sync of our own is planned | nothing. No account, no permissions, no other app |
| In a provider you already use | OpenTasks or tasks.org | whatever syncs it for you — DAVx5 and friends | that app installed, and its read/write permission |
Agendula carries its own copy of the Apache-2.0 dmfs task provider, under its own name — so it coexists with OpenTasks rather than replacing it, and installing one never breaks the other. It is a fork of a proven schema, not a database written from scratch, which is why every CalDAV engine already understands it.
Your tasks are exportable as standard iCalendar .ics files at any time, because
data you can't take with you isn't really yours.
Status: backend complete, UI catching up. Storage, provider, reads and writes, smart-list filtering, a self-scheduled reminder engine, and export are built and unit-tested. The Material 3 Expressive screens are being built on top, one at a time — the storage-mode picker and export screen are not there yet. See
docs/ROADMAP.mdfor status,docs/ARCHITECTURE.mdfor how it's built, anddocs/STORAGE-AND-SYNC.mdfor why storage works the way it does.
Sync sources (by design)
In provider mode Agendula works with anything that writes to that 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.
Translations
Agendula ships in English so far, and would like not to. Translations are managed on a self-hosted Weblate, and partial ones are fine — an untranslated string simply falls back to English.
No coding needed: register on the Weblate server, pick (or request) a language, and translate the strings in your browser. You can also reach this link in the app from the top of Settings → App language.
