Pitch and roll gauges
See how far your vehicle leans nose to tail and side to side, drawn at its real angle against the horizon.
Inclinometer and G-force meter
Breakover turns your iPhone into an off-road instrument panel. Mount it, zero it, and see how far your vehicle leans before the trail decides for you, with no adapters, accounts or signal needed.

What it does
What it does
Zero to any mount
Zero in about 30 seconds on level ground, with an optional turn-around step that cancels out sloped parking spots.
G-force meter
Braking, cornering and acceleration on one plot, with a fading trail and the trip's peaks.

Built for the trail
37 things Breakover does, grouped by what you're trying to do.
Know your angles
6 featuresSpeed, heading and altitude
Speed, heading and altitude along the bottom of the gauges, from GPS and the barometer.
- Heading that suits the moment
- Grade on the pitch gauge
- Steady pitch while driving
- Loose mount warning
- Adjustable smoothing
What these do
- Heading that suits the moment
- Heading follows GPS course while you drive and the compass when you stop, so a steel cab can't throw it off.
- Grade on the pitch gauge
- The pitch reading shows the slope as a percent grade along your direction of travel.
- Steady pitch while driving
- Speeding up and braking lean a pitch reading; with GPS, Breakover removes that lean as you drive.
- Loose mount warning
- A tag appears when the phone is rattling in its cradle, because a loose mount reads the wrong angles.
- Adjustable smoothing
- Choose how much the gauges smooth out bumps, and the full scale of the G-force plot.
Trail data that works offline
7 featuresPosition in four formats
Your position in decimal degrees, degrees minutes seconds, UTM or MGRS, ready to copy and share.
Barometric elevation
Altitude from the barometer and GPS, the change since you started, and air pressure.
Sunrise, sunset and daylight left
Know how much daylight is left before you commit to the next obstacle, worked out on the phone.
- Trip statsPro
- Trip maximumsPro
- Pressure trend
- Magnetic declination
What these do
- Trip stats
- Distance, moving and stopped time, climb and descent, highest point and top speed for the whole trip.
- Trip maximums
- The steepest pitch and roll and the hardest braking, cornering and acceleration of the trip.
- Pressure trend
- The last three hours of air pressure with a plain hint when it is falling fast and weather may turn.
- Magnetic declination
- See the difference between magnetic north and true north where you are, for working with paper maps.
Alerts that don't nag
5 featuresLimit alerts
Spoken and on-screen warnings as you approach the angles you set, announced once per climb, never nagging.
ProLimits you set
Set caution and warning angles for pitch and roll, and see them as colored bands on the gauges.
- Keeps measuring when locked
- Nothing runs until you start
- Quiet while zeroing
What these do
- Keeps measuring when locked
- Measuring and spoken alerts carry on with the phone locked or another app in front, until you tap Stop.
- Nothing runs until you start
- Breakover only uses the sensors, GPS and audio between Start and Stop, so it never drains the battery in your pocket.
- Quiet while zeroing
- Zeroing never starts a measuring session or sets off alerts while you are trying to level the phone.
Vehicles and tracks
6 featuresGPS tracks
Record drives with pitch, roll and g at every point, for one drive or every session, at the detail you choose.
ProVehicle profiles
Keep each vehicle's alert limits and mounts together, and switch between vehicles in Settings or from CarPlay.

- Zeroing saved per mount
- Elevation and tilt chartsPro
- GPX, GeoJSON and CSV exportPro
- Hide where you startedPro
What these do
- Zeroing saved per mount
- Each mount keeps its own zeroing, so moving the phone from the dash to the windshield needs no redo.
- Elevation and tilt charts
- Each saved track shows its elevation profile and pitch and roll over time, with your limits drawn in.
- GPX, GeoJSON and CSV export
- Share a track as GPX, GeoJSON or CSV, with pitch, roll and g included for your own analysis.
- Hide where you started
- Exports can leave out the first and last 200 or 500 meters so home stays private.
Everywhere you look
6 featuresEverything on one iPad screen
On iPad the gauges, G-force and trail data share one screen in portrait or landscape.
Live Activity
Pitch, roll and alerts on the Lock Screen and in the Dynamic Island, with a Stop button.
ProHome and Lock Screen widgets
See whether you are measuring and your last trip's steepest angles, and start a session with one tap.
