The parts of chunk 5 that a build can verify. What is left needs a device or a live server, and is listed in docs/SYNC-PLAN.md rather than guessed at. - Attribution screen in Settings. dav4jvm is vendored, which makes MPL-2.0 §3.2(a) ours rather than a dependency's, so its row points at PROVENANCE.md next to upstream. Hand-maintained: generators read POM metadata, which routinely names a non-SPDX licence and a licence URL that 404s. - Revocation both ways. A 401 marks the account, stops it before the next request reaches the network, and takes it off the schedule from outside the worker — Nextcloud throttles then 429s per source IP, so a timer on a dead app password degrades the user's other clients. On removal, a bounded best-effort DELETE of the app password, or uninstalling never revokes it. - Play compliance: docs/PRIVACY.md linked in the app, declaring Collected and not Shared; an option to delete the account's tasks from the device too; REQUEST_IGNORE_BATTERY_OPTIMIZATIONS confirmed absent. - The server trap matrix as far as a protocol mock reaches, with four tests left @Ignore'd and their reasons written out. - docs/SYNC-PLAN.md records what moves to floret-kit, so that branch is a file move rather than a rediscovery. /code-review high raised 9 findings, all fixed. Three were serious: app-password revocation was aimed at the principal URL and revoked nothing; opening the app put accounts a 401 had stopped back on the timer, because KEEP does not keep cancelled work; and the incremental path advanced the sync token past bodies a failed multiget never applied. Also: four scalars were emitted twice whenever their residue copy survived, which the round-trip corpus could not see. Not done, and needing you: the live server matrix, releaseTest on device, the restore-onto-a-fresh-device check, cert4android, and MKCALENDAR feature detection. Chunk 2's on-device review is still outstanding.
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
keeps its own store, designed around RFC 5545's VTODO — the same tasks DAVx5
(and SmoothSync, DecSync, …) sync out of your CalDAV server. It can also read and
write a tasks provider you already have, for anyone already syncing that way.
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 database | none yet — CalDAV 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's own store is an ordinary app database — nothing is published to other apps, so there is no authority to clash over and no permission to grant. It coexists with OpenTasks rather than replacing it: installing one never breaks the other, and if you already sync through a provider, that keeps working exactly as it did.
Recurring tasks are expanded per RFC 5545, and everything the schema does not model is round-tripped verbatim rather than dropped — so passing your tasks through Agendula does not quietly lose fields a server sent.
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, 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 external-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.
