Torch timers for Shadowdark.
Built by Reese.
- Up to eight torch timers with animated visual effects
- Standard durations from ten minutes to two hours, plus custom overrides and per-torch random variance ranging from ± 0% (default) to 50%
- Round mode: switch any torch to round-based tracking which can be manually advanced
- Pause, reset, fast-forward ("Pass Time" / "Pass Rounds"), and add time or
rounds
- Batch operations allow multiple torches to be updated simultaneously
- Per-torch flame color customization
- Share current state via URL, with a QR code display for a streamlined mobile experience (keep track of your torches by scanning the code with your phone!)
- Go Live: the GM or "Torchbearer" shares a live link; players can watch the
torches update in real time
- Lost your connection? Torchtimer will try to reconnect to the synchronization service
- Clock visibility can be toggled on or off for oneself or for viewers if hosting a session
- Toggle procedurally-generated torch sounds (thus streaming-friendly with no attribution requirement along with showing the app itself)
- Light and dark themes, plus dungeon mode
- Going live is not required for sharing a "snapshot" since the data is all in
the URL
- The timing will be approximately correct no matter when somebody copy-pastes an "offline" link
- No tracking BS
- Torch labels, colors, and duration variance aren't transferred over live
sessions, but through data in the URL
- Why not labels? This is a small community-driven project that can't afford the liability of people transferring sensitive information; but sharing a link using someone else's server is definitely not our problem
- And why not colors? Those connected to a live session should have control over the colors after initially copy-pasting the link
- And not variance? Because it's already baked into the final applied burn duration
- Workaround: copy-paste a fresh live link into a new tab or window to keep labels and colors updated from the Torchbearer
- No instant push updates or notifications to keep project complexity minimal; polling works well enough
