Quick update and big thank you for all. The app has passed Google Play review and is publicly available: https://play.google.com/store/apps/details?id=io.github.kajimae.frictioncircle Not about data handling has changed. I really appreciate everyone who helped with testing and feedback. If you...

Thanks for trying t app and feedback! Accel traction split From the measured acceleration, the app cannot determine whether the driving force is from the front, rear, or all wheels. This setting lets you specify that. Far left = FWD mode. Tire μ A typical value is around 1.0–1.3. Grip...

Thanks! Sorry though — I don’t have a Mac, so I can’t build an iOS version right now. I’ll put it on my Christmas wish list

No Plobrem. After install, the app does not use a cellular connection or Wi‑Fi. It works completely offline and uses only the phone’s built‑in sensors.

Thanks message. It does not connect to the vehicle in any way. The app uses only the smartphone’s built-in sensors and does not communicate with the vehicle. I infer vehicle behavior from the phone’s accelerometer data using filtering and condition-based logic, with the gyroscope used to...

Thanks!! not need now.(2026/03/19) Google requires me to run an additional 14-day closed test for my app. Please help. I need 3 more testers to join.

Small update for those who were following this. The closed test wrapped up on the today, and the app is currently going through store review. Nothing special to announce yet — just sharing progress. My goal is still the same: if visualizing the friction circle helps with understanding vehicle...

Just a quick note to say thank you. I’ve received some helpful input and the project is moving forward as planned. Really appreciate everyone’s cooperation. Fixed an issue where FWD cars showed rear tires contributing to acceleration.Now acceleration force is distributed based on drive-train...

Thanks!! not need now.(2026/03/19) Update for anyone interested in joining the closed beta: Google Play has introduced new requirements for individual developers before an app can be released publicly. To move forward to the final release, I need to reach: • 20 testers • 14 days of continuous...

Hi everyone, I'm an FK8 owner and I’ve been developing a smartphone app that calculates and displays individual friction circles (G‑G diagrams) and G‑vectors for all four wheels, instead of a single combined one. This screenshot shows the moment when the vehicle goes from a left turn to a right...
