G-Force Meter+ Accelerometer shows the G-force your phone feels right now on every axis, then turns each drive, ride or run into a result you can read: press Start, press Stop, and a session card shows the peak G, the average G and how hard you cornered, accelerated and braked. ▶ Live G-force on every axis • Total G on a round gauge with a moving dot for the direction of the force • Lateral (X), longitudinal (Y) and vertical (Z) values side by side • Min, average, max and peak while you record, plus peak chips for lateral, accel and brake • A scrolling chart of X, Y, Z and total G, or a sentence that explains the current G level ▶ Stop and see the session Press Stop and a Session result card appears: • Duration, peak G and average G • Peak lateral, peak accel and peak brake • A second-by-second G trend line (the first 10 minutes of a session) • With the Car activity selected, a plain-language reading of the drive, from Gentle to Very hard, based on the peak horizontal G Every finished session is saved to History automatically (the last 20). A session shorter than 2 seconds is not saved. If you switch apps mid-session, recording pauses in the background and the same session resumes when you return, and a session cut off when the system closes the app is recovered into History on the next launch. Share a result as text in one tap. ▶ History and personal bests Open History from the top of the Meter screen: personal bests, every session with its G trend, your race runs and rolling runs. Export sessions, runs or rolling intervals as CSV. A statistics report CSV unlocks for 24 hours after a short ad. ▶ G-G friction circle A dedicated tab plots lateral against longitudinal G as a trail inside rings at 0.5, 1.0 and 1.5 G, with peak lateral, longitudinal and combined G, so you can see how much grip you used in corners and under braking. ▶ Race mode • 0-60 mph launch timing with raw and rollout times • 60-0 mph brake test with time, distance and speed shed, estimated from the motion sensors • Rolling intervals: 60-120 mph, 100-200 km/h, 30-50 mph or your own range • GPS cross-check with a GPS 0-60 time, a quarter mile time and trap speed. A good fix shows a GPS-verified badge, otherwise the result is labelled as a sensor estimate • Regen profile for electric cars: braking events sorted by their strength into likely regen (gentle) and likely friction (hard), with their maximum G ▶ Set up for your car • Dash or Holder mount, auto-level and Re-level now • Reference 1G (resting reads 1.00 G) or 0G (resting reads 0.00 G) • Display sensitivity from 0.5x to 2.0x for the live gauge; the result card always shows the true values • Activity presets for Car, Roller-coaster, Sport, Elevator and Aircraft explain what each G level means there • A Guide tab with 8 tips on mounting, reading each axis and typical G in daily life • The screen stays on while recording • Interface in 30 languages ▶ Good to know Readings come from the phone's motion sensor, so mount the phone firmly and level it before you record. Launch and braking times are estimates unless they carry the GPS-verified badge. Only drive-test where it is safe and legal. For drivers checking how smooth or hard they drive, track-day and drag-strip fans, roller-coaster riders, and students who want to see physics in numbers. ## Key features - 3-axis G-force tracking - Precision crosshair display - Peak G detection - Real-time chart recording - G-force level guide - Adjustable sensitivity ## Frequently asked questions about G ### Does G-Force Meter+ have ads? Yes, G-Force Meter+ contains advertisements. As a free application, ads are displayed to support its development and maintenance. ### What is the update frequency for G-Force Meter+? G-Force Meter+ was last updated on 2026-06-18. The developer has released updates for version 1.0.13, indicating ongoing support and potential for future improvements. ### What devices does G-Force Meter+ support? G-Force Meter+ is available for iPhone and iPod devices. It is designed to utilize the motion sensors present on these platforms. ### What is the age rating for G-Force Meter+? G-Force Meter+ has an age rating of 17+. This rating is typically assigned due to the nature of the data it measures and its potential applications, which may involve activities considered more mature. ### How does G-Force Meter+ compare to other acceleration apps? G-Force Meter+ offers a unique 3-axis crosshair visualization and peak G detection with a glow indicator. It also includes a G-force level guide for context, differentiating it from simpler acceleration logging tools. ### Can G-Force Meter+ be used offline? The description does not specify offline functionality. However, as a sensor-based application, it likely requires device sensors to be active, which may function without an internet connection for core measurement. ### What is the user sentiment for G-Force Meter+? Based on the provided data, G-Force Meter+ has a rating of 1.0 stars from 1 rating. This indicates a very low user satisfaction score from the single available review. ### Is G-Force Meter+ free to download? Yes, G-Force Meter+ is available for free download. The application is supported by advertisements. ## Version history (last 5 releases) ### 1.0.29 — 2026-09-25 • Press Stop to get a Session result card: duration, peak and average G, peak lateral, accel and brake, and a G trend line • Every session is saved to History automatically, and a History button now sits at the top of the Meter screen • With the Car activity, the card rates the drive from Gentle to Very hard • Czech, Danish, Finnish, Hebrew and Dutch now show their own language ### 1.0.28 — 2026-09-04 The G-G plot adds a Holder mount for a vertical car cradle. Set Mount to Holder so accel and brake still plot when the phone stands upright. Thanks for the reviews and feedback! ### 1.0.27 — 2026-08-30 Store screenshots now show the live 3-axis G meter, the 0-60 race timer, and the G-G friction plot in 30 languages. No Tesla branding on those frames. ### 1.0.26 — 2026-08-11 0-60 runs are now timed from GPS fixes, interpolated between the two readings either side of 60 mph instead of snapping to whichever arrived first — the old method could read up to a second slow. A run that cannot be timed accurately now says so rather than presenting an estimate as a measurement. Recording also starts on the tap, with the ad waiting until your peak g is on screen. ### 1.0.25 — 2026-08-06 Ads no longer interrupt you mid-task. Anything full-screen now waits until you have finished what you were doing, and the app stops showing a blank pause where an ad failed to load. ## More apps by Kyu-Hee Jang - [Calculator+ Tip Tax BMI Unit](https://appshunter.io/ios/app/calculator-plus-tip-tax-bmi-unit/id1587591476) - [QR Lens+ Barcode Scanner Pro](https://appshunter.io/ios/app/qr-lens-plus-barcode-scanner-pro/id1590631012) - [Sound Noise Meter+ dB SPL](https://appshunter.io/ios/app/sound-noise-meter-plus-db-spl/id1593197145) - [Tremor Vibration Meter](https://appshunter.io/ios/app/tremor-vibration-meter/id6759666731) - [Lux Light Meter · Photometer](https://appshunter.io/ios/app/lux-light-meter-photometer/id6759858193) - [Barometer: Air Pressure](https://appshunter.io/ios/app/barometer-air-pressure/id6759883097) All apps by Kyu-Hee Jang: https://appshunter.io/developer/1587578867 ## Related topics [g force meter](https://appshunter.io/ios/topics/g-force-meter) · [g-force meter tracker](https://appshunter.io/ios/topics/g-force-meter-tracker) · [sram force](https://appshunter.io/ios/topics/sram-force) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
