Use Inertia to measure the acceleration of all kinds of vehicles. When taking measurements, please always observe the Highway Code and do not put yourself or others at risk!
Inertia supports 0–100, 100–200, 0–100–0 km/h, 0-60mph, 0-60-0mph and 50-70mph ‘out of the box’. You can also set your own limits*. The measurements are supported by the iPhone’s built-in accelerometer, in addition to GPS. To help you identify the measurements later, you can enter driving modes and make notes for each measurement.*
With the speedometer mode, you can also use Inertia as a cycle computer, for example. It displays your current speed, as well as a trip computer showing distance travelled, average*, maximum* speed and elevation gain*. Inertia includes 5 additional speedometer skins.*
*Pro features – see the feature list below
To ensure the most accurate measurements possible, please note the following:
- Mount your iPhone securely in the vehicle
- Ensure good GPS reception
- Do not operate the iPhone whilst driving - Configure all settings in the app before setting off
