What Is the Metromile Pulse?

The Metromile Pulse is a small wireless device that plugs into your vehicle’s OBD-II diagnostic port to track the miles you drive. The OBD-II port is the same diagnostic port mechanics use to read your car’s data, typically located under the dashboard near the steering column.

The Pulse measures your mileage accurately and transmits the data to Metromile, which uses it to calculate your per-mile charges. Beyond mileage tracking for billing, the device enables app features that provide additional value, turning your car into a smarter, more connected vehicle. The device is provided as part of your Metromile policy.

How to Install the Pulse

Locate the OBD-II Port

Find your vehicle’s OBD-II port, usually located under the dashboard on the driver’s side, near the steering column. Most vehicles made after 1996 have this standardized port. Your vehicle manual can help you locate it if needed.

Plug In the Device

Simply plug the Pulse device into the OBD-II port. Installation requires no tools and takes only moments. The device fits into the port like any standard connector, staying in place during driving.

Activate Through the App

Follow the Metromile app instructions to activate your device and connect it to your account. Once activated, the Pulse begins tracking your mileage automatically, requiring no further action from you.

How Mileage Tracking Works

The Pulse device reads your vehicle’s mileage data through the diagnostic port, measuring the miles you drive accurately. Unlike rough estimates or self-reporting, the device provides precise mileage measurement directly from your vehicle’s systems.

The device transmits this data to Metromile, which applies your per-mile rate to calculate your charges. Your monthly bill reflects the base rate plus the per-mile charges for the miles you actually drove. The accurate tracking ensures you’re charged fairly for your real usage rather than estimated mileage.

Metromile App Features

Beyond mileage tracking for billing, the Pulse enables app features that add value. The car location feature helps you find your parked vehicle, trip history records your driving, and diagnostic alerts notify you of potential vehicle issues detected through the port.

The Daily Mileage Cap and the Pulse

The Pulse device works with Metromile’s daily mileage cap to protect you on long trips. The device tracks all your miles, but Metromile only charges for miles up to the daily cap (often around 250 miles, varying by state). Beyond the cap, additional miles that day aren’t charged.

This means the Pulse accurately records your full mileage for trip history purposes while the billing system applies the cap to protect you from excessive charges during road trips. You get accurate trip data without paying for every mile on unusually long driving days.

Privacy Considerations

The Pulse device naturally raises privacy questions since it tracks mileage and offers location features. Understanding the privacy aspects helps you make an informed decision.

What the Device Tracks

The Pulse primarily tracks mileage for billing, along with trip data and location for app features like finding your parked car. The focus is on usage-based mileage measurement rather than scoring your driving behavior.

The Privacy Tradeoff

Using Metromile means accepting that the Pulse device tracks your mileage and trips. Drivers comfortable with this tracking in exchange for fair pay-per-mile pricing find the tradeoff worthwhile. Privacy-conscious drivers who prefer not to have a tracking device may prefer traditional insurance without mandatory tracking.

What If You Remove the Device?

The Pulse device needs to remain plugged in for Metromile to track your mileage. If the device is removed or stops transmitting, Metromile may estimate your mileage or require the device to be reconnected. Keeping the device plugged in ensures accurate billing based on your actual driving.

If you need to remove the device temporarily, such as for vehicle service, you can typically reconnect it afterward. Contact Metromile if you have questions about device removal or replacement, since proper functioning is necessary for the pay-per-mile model.
