Prove your drift. With data. Every run you push through the circuit stays with you — in real time. GPS, accelerometer, and gyroscope recorded simultaneously, visualizing every aspect of your driving. The gap between you and your rivals is in the data. 【Features】 ・Real-time GPS + sensor data recording ・Map visualization of driving path, drift angle, and weight transfer ・Timeline of sessions by date, showing the top speed and maximum drift angle of each ・External GPS receiver support (Qstarz BL-818GT, BL-1000GT / Dual XGPS160) ・Support for doripod, DORILOG's dedicated sensor device (register it with a QR code and download recorded sessions over Wi-Fi) ・Data file management & sharing ・Includes a sample session, so you can try playback without external hardware 【Important】 The iPhone's built-in GPS has a low update rate and insufficient accuracy for drift analysis. Recording requires a supported external GPS receiver or doripod. All recorded driving data is stored on your device. Nothing is sent to the developer's servers.
