SyncTimer - Ensemble Stopwatch

Synced countdowns and cue sheets for rehearsals and run-throughs. One leader controls the session; all others stay aligned. No accounts. Local-only.

SyncTimer is a rehearsal-first ensemble timer for professional musicians and educators. Run synced countdowns, execute structured cue sheets, and keep every device aligned, so the group starts together and stays together.

SYNCED COUNTDOWNS • Set a countdown fast (type digits on the numpad to enter time immediately) • Start, stop, restart, and cue with stage-ready controls • Built for weekly rehearsals, sectionals, and run-throughs

PARENT / CHILD SESSIONS • One device becomes the Parent (leader) • Other devices join as Children (followers) • Self-correcting sync keeps the session aligned across devices

RICH CUE SHEETS • Build a cue sheet for your rehearsal structure • Add cues and rehearsal marks to organize the run • Trigger events like Cue / Stop / Restart / Loop as part of a repeatable workflow

LIVE GROUP PROMPTS • Send a message to the group at the right moment • Show an image as a visual cue (staging, musical/score fragments, notes, reminders) • Designed for clarity: minimal UI, readable at a distance, fast to dismiss

RELIABILITY-FIRST DESIGN • Built for real rehearsal conditions: predictable behavior, low-friction operation, and dependable group timing
