Regularity Mate: TSD Rally

Regularity Mate is a modern, stress-free tool designed for Time-Speed-Distance (TSD) and Regularity Rallies. It replaces expensive rally computers and complex cockpit setups with the devices you already own. Designed by rally enthusiasts for classic car navigators, this app focuses on readability, precision, and ease of use to reduce cockpit chaos and keep your focus on the roadbook.

SHARED COCKPIT (DRIVER DISPLAY) Rallying is a team sport. Connect a second device to act as the Driver's display. Cross-Platform: Seamlessly connect an iOS device with another smartphone. Navigator: Controls the timing and sees all details. Driver: Sees a simplified, large-font display of the Target Speed and Pace Indicator (early/late). Helps reduce verbal communication and stress inside the car.

FLEXIBLE PRECISION Choose the distance source that fits your class and budget: GPS Timing: High-accuracy raw GPS tracking for reliable distance measurement. External Sensors (Pro): Connect generic Bluetooth wheel speed sensors or OBD-II scanners for hardware-level precision.

ESSENTIAL TOOLS Clean UI: High-contrast text designed to be readable while the car is shaking. Pacing Bar: Simple visual indicator to show your deviation from the ideal time. Split Timer: A secondary stopwatch/tripmeter for complex tulip sections. Steering Wheel Controls: Use a Bluetooth media button to trigger the Split Timer or adjust distance without touching the screen on bumpy roads.
