G FORCE makes your iPhone or iPod Touch a handy vehicle G-Force meter. A nice looking enhancement to the dash of your car, too.
Quantify the G-Force you experience in the vehicle (e.g. during acceleration, braking, drifting, cornering etc) or perform a quick dyno.
Its unique "Sound Alert feature" provides alert sound when the g-value exceeded a user selected limit.
(1) "Quick & Simple Calibration"
Simply press the start button and G FORCE takes only about 0.5 seconds to calibrate to your iPhone's tilt angle.
(2) "Real Time Display"
Two "Linear Gauges" and two "Digital Displays" show the real time lateral (e.g. cornering) and longitudinal (acceleration, braking) G values.
(3) "Peak Hold"
Adjustable "Peak Hold Duration" helps you monitor peak values.
(4) "Graphical Peak Hold Indicators"
Distinctive graphical peak hold indicator makes observing peak values a quick glance.
(5) "Adjustable Audio Alert"
Provides alert sound when the G-Forces exceeded a user preset "threshold".
(6) "Adjustable Gauge Scale"
"log Scale" and "Linear Scale" helps you utilize the "Linear Gauges" for different conditions. e.g. Use log Scale in "mild" acceleration conditions or use "Linear Scale" in "aggressive" acceleration conditions.
(7) "Session Maximum Records"
Shows all the maximum G values in the current session.
(8) "Large Operation Buttons"
Facilitates quick and easy operation.
(9) "Theme Switch"
Switch between the Classic and Graphite Theme to suit your taste.
With its nice interface and unique features, you would like G FORCE even though you may have already got other g-meters like dynolicious or even a hardware equipment.

Ratings and Reviews
Nice app very useful at Amusement Park
I used the app to measure the G force while driving my car. There were all under 0.5 G. I set my alarm to buzz whenever the measurement goes beyond 1 G. I suppose if I suddenly slammed on my brakes while speeding up to 75 mph it might trigger the alarm. I believe this app might be more useful at amusement parks especially roller coasters. I used it inside an elevator and it measured less than 0.2 G.
Awesome app. I would like to have a video background. Here is why: I could run around a skid pad, and see what my max g-force is, then I could compare that to recording of an auto cross with g-force overlay. If in the video I see that on certain corners I am loosing traction at a lower force, that means I know where I'm not being smooth enough.
Works as advertised. Simple to use.
I would like to see 3D information added to future versions.
Also, it would be nice to plot acceleration as a function of time for a minute or so at one-second intervals. Of course, one would like o read out a file containing that data.
With Family Sharing set up, up to six family members can use this app.
