About this app

Master your timing in TSD and regularity rallies! Regularity Mate is your affordable, easy-to-use digital co-driver and tripmeter. Perfect for classic car, oldtimer, and historic rally events, it replaces expensive rally computers with the device you already own. Focus on your roadbook, not complex hardware! Regularity Mate is free to try, with a 🔒 one-time purchase to unlock all Pro features. No subscriptions, ever.

Key Features:

🎯 Stay on Pace: See your target distance vs. traveled distance and current vs. target speed. An intuitive Pacing Bar shows if you're ahead (blue) or behind (red) in real-time.

🛰️ Flexible Precision: Start with your phone's GPS, then add map matching or high-precision GPS from a connected Garmin watch. For pro-level accuracy, unlock Pro to connect a Bluetooth Wheel Sensor (CSC) or an OBD-II adapter.

🗺️ Offline Maps & Map Matching: Download maps for any rally. Our algorithm snaps your GPS to the road, improving distance accuracy even with weak signals. Toggle it on or off at any time.

🚦 Intuitive Rally Setup: A simple editor lets you define segments (distance, average speed) and checkpoints. Or, use Training Mode: record a drive, mark points on the fly, and save it as a new rally.

📊 Analyze & Share: Review your performance with detailed Accuracy Reports and export your tracks to GPX. Share or back up your rallies easily via QR Code or file.

⏱️ Stay Alert: Get clear audio and visual countdowns for upcoming speed changes, checkpoints, and the rally finish.

🚗 Achieve Maximum Precision: Regularity Mate offers great flexibility. For professional-level results, 🔒 unlock Pro with a single one-time purchase. This permanently unlocks support for Bluetooth wheel sensors (CSC) and OBD-II adapters, complete with calibration tools.
