Lap Doctor

Lap Doctor turns your iPhone into an automatic GPS lap timer for closed-course riding. Create an event, choose your settings, secure your phone, and arm the timer. After you remain stationary for the selected idle time, Lap Doctor detects your launch and establishes a virtual start line. Cross that line in the same direction to record laps. Return to stationary to finish the session. REVIEW YOUR RIDING • View lap times and session results. • Organize sessions by event. • Add session names and notes. • Remove unwanted laps from results and restore them later. SET UP YOUR TEST • Adjust the minimum launch speed and stationary idle time. • Choose how many laps to complete before timed recording begins. • Set Minimum Laps to 0 for straight-line tests. RECORD AND EXPORT • Continue recording with the screen locked when the required location permissions are enabled. • Export session GPS tracks to KML for viewing in compatible mapping software. • Read the built-in Quick Start and How To help without an internet connection. GPS PERFORMANCE Timing and track quality depend on GPS reception, phone placement, and riding conditions. Mount your iPhone securely with a clear view of the sky. Location and background-location permissions are required for the corresponding recording features. Designed for closed-course use. Configure the app before riding and do not interact with your phone while moving. Questions or feedback? [email protected]
