PeakG - G-Force & Motion Meter
Track Sessions, Export Data
Free · Designed for iPhone. Not verified for macOS.
Track every force, every flight, every run. Real-time G-force monitoring with session recording — now with standalone Apple Watch support. No account required.
PeakG turns your iPhone and Apple Watch into a precision G-force meter with session recording. Whether you're a pilot perfecting maneuvers, a driver pushing limits on track, an athlete pushing your limits, or just having fun in a rollercoaster — know exactly what forces you're experiencing in real-time.
REAL-TIME MONITORING
See G-forces, speed, and altitude update live as you move. The clean, glanceable display shows you what matters without distraction. Your Apple Watch works completely standalone — leave your phone behind and record sessions directly from your wrist.
SESSION RECORDING
Tap to start recording, tap to stop. Every session captures continuous G-force, speed, and altitude data at high frequency. Review your runs with interactive graphs that reveal exactly what happened at every moment. Name and organize sessions your way.
POST-SESSION ANALYSIS
After each session, see the numbers that matter:
- Peak and minimum G-force
- Average G-force across the session
- Maximum and average speed
- Altitude range (max and min)
Scrub through the timeline graph to pinpoint specific moments — that hard banking turn, the drop on the roller coaster, the moment you touched the brakes.
EXPORT YOUR DATA
One tap exports your entire session as a CSV file with timestamped G-force, speed, and altitude readings. Import into spreadsheets, analysis tools, or store for memories. Your data, your way.
STANDALONE APPLE WATCH
Record complete sessions on Apple Watch without your iPhone nearby. Perfect for cockpit use, track days, or any activity where carrying a phone isn't practical. When you're done, sessions sync automatically to iPhone for detailed review and export.
BUILT FOR YOUR UNITS
Switch between the measurements that make sense for you:
- Speed: knots, mph, or km/h
- Altitude: feet or meters
Aviation, motorsports, or any exciting experience — PeakG speaks your language.
COMPLETELY PRIVATE
Everything happens on your device. No account to create, no data uploaded to servers, no tracking. Your session data stays on your iPhone and Apple Watch until you choose to export it.
