Marshal

What it does

• Live timing and leaderboard — lap times, positions, and gaps update as transponders cross the line
• Practice, qualifying, and race modes — each with configurable duration and minimum lap time
• Smart voice announcements — lap times, lead changes, fastest laps, and final-lap warnings called out in real time
• Garage management — save your tracks, drivers, and vehicles with transponder IDs for quick setup
• Ghost participants — fill out the grid for solo practice sessions
• PDF race results — export detailed results with lap-by-lap breakdowns and share via AirDrop, Messages, or Mail
• Live Activity — follow the race from your Lock Screen or Dynamic Island

Hardware support

Marshal works with existing IR transponder timing hardware — no need to buy new equipment.

Bluetooth (iOS, iPad, macOS):

• LapMonitor (BLE)

• Tucker — our own USB-to-BLE bridge, so an i-Lap decoder works on iPhone and iPad

USB (macOS only):

• i-Lap decoder

Voice announcements

Four announcement modes to match your track:

• None — sound effects only
• Minimal — session bests and final laps (for fast tracks under 15 seconds)
• Standard — balanced callouts with smart lap-time filtering
• Verbose — full detail with lap numbers, positions, and gaps

Marshal uses smart name handling (first name when unique, full name when there are two Michaels) and filters out obvious crashes so you only hear what matters.

Built for casual racing

Marshal is designed for backyard sessions and club practice days — fast setup, easy starts, and a race view that keeps everyone in the loop. No subscriptions, no accounts, no cloud. All data stays on your device.
