## What is TraceG?

TraceG turns your phone into a private G-meter for drivers who want to see every road in a more dynamic way.

Many cars do not include a built-in G-force display. TraceG gives you a simple way to record lateral and longitudinal G-force with your phone: mount it securely, calibrate, and start a trip. Acceleration, braking, cornering, and quick transitions are plotted in real time on a clean circular meter.

You can switch between 2D and 3D views at any time. The 2D view shows your G-force trail on a flat map, while the 3D view adds speed as the vertical axis, helping you see how motion, direction, G-force, and speed connect as you drive.

After each trip, TraceG saves a detailed G-profile with peak values, motion trails, trip history, and smart ratings. You can review where the car felt loaded, compare different drives, and export raw data for further analysis.

TraceG is not a driving score and does not judge your behavior. It is built as a personal, local-first driving instrument for people who enjoy the feel of a good road and want the data to match.

Key features:
* Live circular G-meter with lateral and longitudinal G-force
* 3D trip review that adds speed as the vertical dimension
* Peak values for left, right, acceleration, and braking
* Trip history for saved drives
* Raw data export for further analysis
* Local-only data storage
* Local-only data storage, no account, no cloud sync, no 3rd-party tracking
