Stopwatch — Quick Settings stopwatch

What it is

A stopwatch that lives in Quick Settings. Swipe down, tap the clock tile to start, tap again to pause, long-press to reset — with a live mm:ss count on the tile and a floating pill at the top of the drawer while it runs. Time a focus block, a workout, a boil, an exam section, without leaving your notebook. The screenshot shows the tiles in the Quick Settings toggle row.

Features

• One tap from Quick Settings — tile toggles run / pause; long-press resets to 00:00.
• Live mm:ss overlay on the tile (bold while running) and a floating ⏱ mm:ss pill at the top of the drawer whenever the clock is running or paused above zero.
• Survives restarts — state is written to a small file on the device, so the count is correct across Quick Settings re-opens and xochitl restarts. A clock left running through more than 30s of device sleep auto-resets, so you never return to a wildly inflated time.
• Self-contained + private — a plaintext qmldiff patch, no network, no telemetry. You can read every line before installing.
• Co-tenant safe — every QML id is namespaced (swx*) so it won't collide with other installed qmd tweaks.

Requirements

• reMarkable Paper Pro, firmware 3.26.0.68. Built for firmware 3.26.0.68 exactly — qmldiff patches key off the firmware's QML, so other versions are untested.
• xovi + the qt-resource-rebuilder extension (free; links in the README).
• No other paid item required.

Install

Copy one file to the device, restart xochitl the xovi-safe way (exact commands in the README), and the tile appears in Quick Settings. Uninstall = delete the file, restart, remove the state file. No system files are modified on disk.

Honest caveats

• This product modifies the on-device user interface at runtime. It contains no reMarkable software; changes are applied to files already present on your device and are fully removed by uninstalling.
• reMarkable has no speaker, so the stopwatch is silent by design — it just counts.
• This patches the system UI via qmldiff (that's what makes a QS tile possible) — unlike our AppLoad apps. The README includes the one-line SSH recovery should any qmd on your device ever misbehave: delete the file, restart. Nothing persistent is touched.
• qmldiff patches are firmware-sensitive; tested on 3.26.0.68, updates best-effort after firmware releases.

Also available

• Timer (AUD 12) — the same idea for counting down, with a duration picker and a "Timer ended" alert.
• timerMode combo (AUD 18) — Stopwatch + Timer together, cheaper than buying both singles. Buying both singles? The combo is cheaper. Install the combo or the singles, never both — they share element ids.
