makiolaj 83c5e9fe3f feat(shell): the navigation host, four tabs and the live pill
`NavigationSuiteScaffold` gives the bar on a phone and the rail on a wide
layout from one declaration. Each tab keeps its own back stack; re-selecting
a tab returns to its root, and predictive back is wired only where back
actually goes somewhere.

The pill is the running-state surface from PLAN §9: it floats above the bar,
speaks for whichever subject is closest to needing attention, and pauses or
stops it from any tab. Its callbacks are gated on a live subject, so a second
tap during its exit animation cannot restart a timer the user just reset.

The notification permission is asked once, and the flag is written from the
request's result rather than before it — a process death mid-dialog leaves
the ask due again rather than recorded and never made. Three tabs are empty
shells until M5 through M8 fill them.

Clockula

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

CI Android 10+ Kotlin + Compose Material 3 Expressive MIT License

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.
