Corner Speed - Your Ultimate Motorcycle Riding Companion

Perfect Weather for a Ride?

Corner Speed is a professional motorcycle riding tracker designed for passionate riders. Whether you're a canyon carver, daily commuter, or someone looking to improve your riding skills, Corner Speed is your perfect riding companion. Gear up, launch Corner Speed, and make every ride more exciting.

Real-time Dashboard - Track Every Moment

The app features a beautifully designed real-time dashboard with intuitive circular progress indicators displaying your current speed and lean angle. The dashboard shows "Last Corner" statistics including lean angle and average corner speed, allowing you to review your performance during straightaways. Support for both landscape and portrait modes ensures clear visibility regardless of your phone mounting setup. The pure black background design remains readable in bright sunlight, while dark mode support reduces screen glare during night rides.

Precise Lean Angle Measurement - Push Your Limits Safely

Corner Speed utilizes your iPhone's built-in gyroscope and accelerometer, sampling at a high frequency of 0.25 seconds to accurately calculate your motorcycle's lean angle through corners. This feature helps you objectively understand your riding limits and continuously improve within safe boundaries. The system automatically records key metrics for each ride including maximum lean angle and average speed, helping you analyze your riding performance.

Mid-Ride Refueling - Keep Your Journey Going

The new Travel tab helps you find what you need without breaking your ride. Once you start, the app pinpoints your location on a sleek night-mode map and lists nearby gas stations and convenience stores. Each spot shows live direction guidance, straight-line distance, estimated arrival time, and opening status, so you can pick the closest, most convenient stop at a glance. Tap once to open navigation in Apple Maps or Google Maps, and the app remembers your preferred app for next time. The interface carries over the dashboard's carbon-fiber racing style, with a fluorescent-orange metal dial and large distance figures that stay readable on the move. Even in remote mountain areas with poor signal, it falls back to previously cached data so you can still find supplies offline.

Complete Route Recording - Relive Every Journey

Integrated with map services to automatically record your riding route. Each ride saves complete GPS coordinates, timestamps, speed variations, and lean angle data. You can review all past rides in the records page, visualize routes on the map, and relive every exciting cornering moment.

Cloud Sync - Share Your Routes

Support for cloud synchronization allows you to upload all riding records to cornerspeed.com and share your routes with riders worldwide.

Local Storage - Works Offline

Using local database technology, the app continues to record all data even in remote mountain areas without network coverage. Once you regain network connection, you can sync records to the cloud, ensuring data integrity.

Multi-language Support - Serving Riders Worldwide

Available in Traditional Chinese, Simplified Chinese, and English interfaces, making it accessible to riders from different regions.

Important Usage Notes

. Use a sturdy phone mount. When possible, mount it on the bike frame rather than handlebars, as handlebar mounting may affect lean angle measurement accuracy
. Ride safe - only check the dashboard when road conditions permit. Corner Speed records all information for you to review on the map after your ride
