Description
FEEL THE FORCE.
GSpike turns your iPhone and Apple Watch into a precision G-force meter. Measure acceleration forces in real time, record sessions, and track your peak G's — on rollercoasters, go-karts, ski slopes, and beyond.
▸ REAL-TIME G-FORCE GAUGE A beautiful, color-coded gauge shows your current G-force with instant response. Watch the ring change from cyan to green to orange to red as forces increase.
▸ APPLE WATCH COMPANION Strap on your Watch and measure G-forces from your wrist — perfect for rollercoasters, go-karts, or track days when your phone stays in your pocket. Independent accelerometer, full session recording, automatic sync.
▸ LIVE ACTIVITY See your G-force reading right on your Lock Screen while recording. No need to unlock your phone.
▸ SESSION RECORDING Hit record and capture every moment. Each session saves your peak G, average G, duration, and a sparkline chart. Compare runs, track progress, build your history.
▸ DUAL DEVICE Use iPhone and Apple Watch at the same time? GSpike records two separate sessions — one per device — so you can compare phone vs. wrist measurements side by side.
▸ AUTOMATIC SYNC Sessions sync instantly between iPhone and Apple Watch. Record on your Watch, see it on your phone. Delete on one device, gone from both.
