Instant sync.
No on-stage manual clockstart, no cables, no worries.
SyncTimer™ pulls every iPhone in the room into a ± 5 ms grid, so you can start, stop, and cue stopwatch pieces without showing a visible onstage downbeat ever again.
SyncTimer™ v0.5 currently features:
Clock-perfect countdowns – Pre-roll timers snap your ensemble into ride-off position with precision.
30-device auto-lock – LAN/Wi-Fi or Bluetooth; no cables, routers, or stage boxes needed.
Cue-list playback – Trigger silent hits and rehearsal markings right from the conductor’s phone.
Band-room ready – 50 % Apple School Manager discount and volume-licence delivery—IT just signs off and hits “install.”
Privacy by default – No logins, no cloud, no data leaves the stage.
Multi Device Lock. Smart Controls.
SyncTimer™ features customizable UI, including a performance oriented landscape mode with only the info you need to see during performance: time, upcoming cues, and stopdown events.
The bigger the ensemble, the longer the “Ready? … 3-2-1-GO!” chaos. Mis-counts waste rehearsal minutes, and the further you stand from the conductor, the worse the drift. SyncTimer™ solves it in a single tap:
Instant group lock – Up to 30 iPhones snap to the leader within three seconds over Wi-Fi, Bluetooth LE, or Bonjour.
Powerful, musician-focused controls – lock your countdown, stop, or reset buttons for peace of mind during performance. No other stopwatch app currently offers this.
Lock all child devices to ensure everyone makes it through the performance without accidental starts and stops.
Auto-heal – Drop a phone, swap a hotspot, or walk out of range; the moment a device returns it re-aligns without manual resets.
Cue-List Control
Program once—hit every mark, every time.
SyncTimer™ lets you draft a timeline of on-the-dot events—stops, cue points, and automatic restarts—right on your phone before the run-through starts.
One-tap event cycling – The red → blue → green button toggles Stop ▸ Cue ▸ Restart so you can lay down markers in seconds.
Drag-to-reorder carousel – Need to shuffle movements or bump a fermata? Just slide the chips left or right; no re-typing.
Locked to the global grid – Every event fires off the same ± 3 ms master clock that keeps the ensemble in sync, so nobody drifts ahead or behind.
Non-destructive during performance – Event buttons disable the moment the countdown starts, preventing accidental edits mid-show.
Whether you’re cueing electronic hits in a multimedia piece or timing blackout-to-blackout transitions, the Cue-List keeps you on schedule with conductor-level confidence.
