About
G-Force Atlas turns your iPhone into a precise driving data logger for cars and motorcycles. Mount the phone, tap Start and drive. The app measures the G-forces in every corner, braking zone and acceleration, and afterwards shows you exactly where on the road it happened.
LIVE WHILE YOU DRIVE
- G-G friction circle with lateral and braking/acceleration G in real time
- Big speedometer with top speed
- Automatic 0–100 km/h whenever you accelerate from standstill
- Session records: top speed, max lateral G, hardest braking, best 0–100
- Altitude and gradient
- A map that follows you and draws your route as you drive
- Swipe live pages: G-G, speed, records (and lap timing in track mode)
ROAD
- Day summary with distance, top speed and G intensity along the route
- Top 5 lists for corners, braking, acceleration and fastest stretches
- Tap anywhere on the route to see speed and G-forces at that exact point
- Lean-angle analysis for motorcycles in summary and analytics
TRACK
- Lap times from GPS start/finish crossings, with sectors
- Live delta to your best lap, plus theoretical best
- Lap analysis: compare laps corner by corner, with braking points and entry, minimum and exit speed
0–100 KM/H
- Captured automatically during normal logging – no separate guided mode
- Best time and all runs appear in records, summary and PDF
SHARE AND KEEP
- PDF report from every session with map, key figures, G-G circle, graphs and top 5 lists
- All sessions are stored locally on your phone. No account, no cloud.
Watch the demo: G-G, speed and records, then a dynamic example from Rudskogen Motorsenter. An extra Trollstigen example sits under Sessions (can be hidden in More).
Languages: Norwegian, English and German – switch under More.
Always drive legally and safely. Use a track to explore the limits. Do not operate the phone while driving.
