makiolaj 26f1effb4f feat(worldclock): the tab, the picker, and the face that answers at a glance
A hero face for home over a list of cities, each carrying its time, its offset
and how many days apart it is from you. The dial morphs between a circle and a
sun with the hour *there*: the one showpiece M0 reserved, spent on information
rather than decoration — a glance says "it is the middle of the night for them"
with no sentence needed.

The picker searches the device's own zones by word prefix. The list reorders by
drag **and** by move-up/move-down actions, because a drag-only reorder is
unreachable by a screen reader; each row reads as one sentence rather than
three texts in child order. Home is set by hand or left following the device.
At the twenty-fourth city the refusal is written on the screen, not only in the
content description.

Clockula

A modern Material 3 Expressive clock app for Android.
Alarms, timers, stopwatch and world clock. Open standards, no account required.

Clockula is the clock sibling to Calendula (calendar) and Agendula (tasks). The name follows theirs: clock, given Calendula's -ula ending. A Calendula flower head is botanically a cluster of many small florets, so the three apps are florets of one bloom — and they share one, floret-kit.

🚧 Early development. The spec is locked; the app is being built. See docs/ROADMAP.md for where it actually is.

The honest difference from its siblings

Calendula is a pure front-end over Android's CalendarContract. Agendula speaks the dmfs TaskContract. Both put a good interface on a standard someone else already maintains.

There is no open provider behind a clock. Alarms, timers and laps are Clockula's own data, so Clockula is the first app in the family to own its storage — by design, not as a fallback. What that commitment is replaced with is the first section of docs/PLAN.md, and it comes down to three things:

  • Clockula speaks Android's standard alarm contract. It implements android.provider.AlarmClock in full, so your assistant and your automation apps can set alarms and timers in it exactly as they would in any stock clock, and the system status bar and lock screen show its next alarm.
  • World clocks are IANA time zones, not a bespoke city list that goes stale.
  • Your data exports to a documented, versioned JSON file whenever you want it, because data you can't take with you isn't really yours.

Alarms that actually ring

An alarm app is only worth having if you can trust it, so Clockula treats that as the feature rather than the plumbing. Alarms are scheduled as real alarm clocks — doze-exempt, visible to the system — and re-resolved against your current time zone whenever anything moves underneath them, so DST and travel don't silently shift them.

When something on your device would stop an alarm ringing, Clockula tells you which setting it is and takes you there, instead of failing quietly at 7am.

Documentation

Start with docs/: PLAN.md is the spec and the reasoning, ROADMAP.md is the status, ARCHITECTURE.md is how the code is put together, and RELEASING.md is the release runbook.

Building

git clone --recurse-submodules https://codeberg.org/jlmakiola/clockula.git
cd clockula
./gradlew assembleDebug

floret-kit is a submodule built from source as a Gradle composite build, so --recurse-submodules is not optional. The included build needs to find the Android SDK on its own: either export ANDROID_HOME, or drop a sdk.dir=… line in a (gitignored) floret-kit/local.properties.
