G-Field Recorder is an easy-to-use and powerful data acquisition and analysis system for iOS device deployments. G-Field Recorder logs, plots, and replays: - 3-axis acceleration fields - 3-axis rotational displacements - Ground speed - Altitude - Distance - Displacement - Course Use this app to assist your analysis of experiments, sports performance, drone behaviors, land vehicle and watercraft actions, security applications, structural behaviors, and more. All of your data is logged on your device, where you may retain it indefinitely, share, or delete the files of your choosing. All data files are easy to export in CSV format via AirDrop and other methods (e.g. Slack, email, LinkedIn ...) available on your device. Developed for NASA payloads, G-Field Recorder is resistant to data loss from impacts, continuously saving your data to permanent storage in case of a severe upset event that damages your device (e.g. you crash your drone). Features: - Logs and plots of motion data: -- 3 Axis Acceleration Field -- 3 Axis Rotations (Pitch, Roll, and Yaw) - Virtually unlimited recording time. The collected data is automatically stored in as many sequentially indexed files as required, up to about 5 MB per file (for easy search and review). Data storage capability is up to the max storage availability on the device. - Programmable data acquisition control: - Relative start time - Absolute start time - Relative stop time - Acceleration reference frame is configurable: -Choose to ignore or sense gravity - Select reference frames: Proper, Fictitious, or Coordinate acceleration - Remote control and monitoring via Apple Watch: - Apple Watch can start and stop data collection, overriding any device-programmed start and stop times - Apple Watch can set the acceleration reference frame - Set sampling frequency from vanishingly small (e.g. 0.001 Hz) up to 100 Hz - Computed averages and extrema of are automatically logged for all recorded motion data - Rewind and instant playback of recorded data - Text notes and an image can be added to each stored data file - Selectable animated icon graphics GPS Package In-App Purchase (recommended ) -- Ground Speed, Course, Altitude -- Distance & Displacement -- Illustrated path overlayed on Apple Map

Ride Forces records g-forces on roller coasters and amusement park rides with your iPhone or Apple Watch. View graphs, analyze stats, and share the forces of your favorite rides. A must have app for thrill seekers, roller coaster enthusiast, and physics nerds. Standard Recording: Captures the g-forces of rides and roller coasters. Provides stats and graphs of g-forces in three dimensions. - Records force data from accelerometer - Requires motion tracking permissions Subscribe to Ride Forces Pro to capture advanced recordings. Advanced Recording: In addition to capturing the force data of a standard recording advanced recording captures rider orientation, GPS data, and weather conditions. This reveals additional ride information including: identifying airtime/hangtime, inversions, orientation angles, a map of ride location, temperature, wind speed, and wind direction. A Ride Forces Pro subscription is required to capture advanced recordings. Advanced recordings can be viewed, edited, and shared with or without a subscription. - Records force and orientation data using multiple sensors including accelerometer and gyroscope - Records GPS data - Records weather conditions (requires internet connection) - Requires location and motion tracking permissions - Records for a maximum of 15 minutes - Advanced recording will fallback to standard recording if the app is closed while recording Privacy Policy: https://rideforces.com/privacy/ Terms of Use: https://rideforces.com/terms/

Verdict
The clearest difference is rating: Ride Forces at 4.8 against G's 3.7. Ride Forces also leads on review sentiment (80% vs 50%) and ratings volume (48 vs 9). G's advantage is update cadence (every 4 days vs every 5 weeks) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. G sells 2 one-off in-app purchases and Ride Forces sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Ride Forces holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Ride Forces has 48 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 50% of G's written reviews are positive against 80% of Ride Forces's.
G ships an update every 4 days, Ride Forces every 5 weeks. Both last shipped on November 2, 2026.
