## What is DORILOG?

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
・External GPS receiver support (Qstarz BL-818GT, BL-1000GT / Dual XGPS160)
・Data file management & sharing

【Important】
The iPhone's built-in GPS has a low update rate and insufficient accuracy for drift analysis.
An external GPS receiver is required for recording actual run data.
(Built-in GPS is available for debugging and connection testing only.)

All recorded data is stored on your device. Nothing is sent to external servers.
