A motion meter with an early App Store record
The G FORCE App Store listing describes a vehicle-oriented acceleration meter and includes a version history beginning in August 2008. It identifies Cross-Discipline Technology Limited as the seller. That record is a plausible match for this period’s G-Force subject and distinguishes it from unrelated games with similar names.
A display is not a validation study
The developer describes gauges, calibration, and peak indicators. Those are product features, not independent proof of measurement accuracy. The number on a phone should not be treated as a certified vehicle test or a substitute for appropriate professional equipment.
To interpret a reading, you need to know what quantity is shown, which axis it refers to, and what the application has done during calibration. A large peak without context says less than a clear explanation of the measurement conditions.
Keep observation separate from driving
Do not operate a phone or attempt aggressive maneuvers to generate an interesting reading while driving. This page offers no road-testing procedure. If motion data is needed for a legitimate project, use a suitable supervised setting and equipment appropriate to that task.
For software research, the safer questions are documentary: can the app explain its units, save a session, and distinguish a peak from a continuous record? Check the current documentation rather than inferring those capabilities from a screenshot.
Check an old app carefully
A live store page does not guarantee performance on every current device. Review compatibility, update history, and available support in your storefront before purchasing. This introduction is based on the published listing and does not claim hands-on calibration, vehicle performance results, or a verified measurement accuracy.
