G-Force Monitor — Live Acceleration, Braking & Cornering

Measure braking, acceleration, and cornering forces in real time with your iPhone. This view is useful for track days, driving instruction, performance testing, passenger-comfort checks, and comparing how different vehicles or setups behave.

In the app, this mode is labeled G-Force Panels. It uses G-Force + Bowl as the main central panel.

Best for

• track day drivers who want to see braking and cornering load live
• driving instructors who want to explain smooth vs abrupt inputs
• vehicle testers comparing tires, suspension, or route sections
• anyone who wants a live g-force meter instead of raw accelerometer values

When to use this

Use G-Force Monitor when you want a live braking, acceleration, and cornering display while the vehicle is in motion.

When not to use this

Do not use this page if your main question is long-run route quality or dominant vibration frequency. Use Motion Quality or Resonance Scan instead.

What you get

• a live G-Force dashboard with central and micro panels
• directional force interpretation in real time
• optional overload alerts for stronger events
• quick comparison across maneuvers once the frame is mapped correctly

Mode

Open MENU > Modes > Engineering > G-Force Panels.

Use this mode when you want the standard G-Force layout: a richer central panel for direction and history, plus a compact micro panel for quick directional peaks.

Central area

The default central area in this mode is G-Force + Bowl.

To pick it manually, open the main panel menu, choose Pick what to show here, then in Screen area options > Engineering choose G-Force + Bowl.

The bowl shows current force direction, distance from center shows strength, and the history strip helps you judge whether the transition was smooth or abrupt.

For a panel-focused explanation, continue to G-Force Bowl .

Micro area

G-Force + Bowl is also provided as a micro panel.

Shared settings

The whole G-Force family uses the same settings screen.

Start with Frame mode, because it decides what the app means by Forward, Braking, Left, and Right. Then configure Overload alerts only after the directions already make sense.

Good first setup

• Start with Auto-learned if you are checking the feature for the first time.
• Switch to Fixed orientation when the phone position is stable and you want repeatable results immediately.
• Turn alerts on only after the displayed directions and magnitudes already make sense.
• Use one safe firm brake and one sharper corner to confirm the setup before trusting the readings.
