Getting started

What you need

  • An iPhone with the CarPrint TestFlight beta (Step 1 below).
  • An OBD2 BLE adapter plugged into your car’s OBD2 port (OBD-II). We’ve tested the OBDLink CX, Veepeak OBDCheck BLE, and Vgate iCar Pro BLE. Other OBD2 BLE adapters may work as well.
  • A compatible vehicle.

Step 1 — Install the CarPrint app

  1. Install Apple’s TestFlight app.
  2. Click CarPrint View in TestFlight and install.

Step 2 — Welcome & CarPrint Settings (first launch)

  1. On first launch, CarPrint shows Welcome. Open CarPrint Settings from the gear icon on the Live tab upper right.
  2. Enter Driver name or alias and Vehicle name, then tap Save. Or tap Skip for now.

Step 3 — Allow iPhone permissions

The OBD2 records trips on your phone (route maps and the trip stats).

  1. Location: allow when prompted. CarPrint requires While Using the App or Always. If available, choosing Always is more reliable if your phone screen locks.
  2. Make sure your phone’s Bluetooth is turned on: iPhone Settings → Bluetooth, but do not click Connect.

Step 4 — Plug in the OBD2 BLE adapter

  1. Plug the adapter into the OBD2 port (usually under the dash, often near the hood release). You may want to use a mirror to find it. The wider part of the port and adapter should be closer to the car floor in most vehicles.
  2. Start the engine. Engine must be running for the app to connect.
OBDLink CX, Veepeak OBDCheck BLE, and Vgate iCar Pro BLE adapters
Supported adapters. CarPrint has been tested with OBDLink CX, Veepeak OBDCheck BLE, and Vgate iCar Pro BLE.

Find the port. Look under the driver-side dash. In many cars the OBD2 port sits near the hood release lever.

Orientation. The port is a small trapezoid. In most vehicles the wide edge faces the floor — match that when you plug in the adapter.

Plugged in. Push until the adapter seats fully. Status lights (green power, blue link) mean it is ready for CarPrint to connect in Step 5.

Step 5 — Connect OBD2 in CarPrint

  1. Open CarPrint → Live tab.
  2. Tap Start.
  3. Watch the status line: Scanning… → Connecting: [adapter name] → Ready (polling) • [name].
  4. Wait for RPM to show. The first time it may take up to 90 seconds.

Step 6 — Drive and Record a Trip

  1. Drive.
  2. When finished, tap Stop.

Notes:

  • Trips shorter than one minute are not saved.
  • During the drive: Keep CarPrint on Live and your iPhone screen on for the whole trip.
  • While you’re recording, Stop is red. If Stop is grey, you’re not recording — tap Start again.
  • Locking the screen or using CarPlay can stop recording early during this beta.
  • At your destination: Stay on Live and tap Stop before you lock the phone or leave the car.

Step 7 — Confirm the trip on your phone

  1. Open the Trips tab — your drive should appear.
  2. Tap a trip for map, fuel, and scores.

Step 8 — Web dashboard

  1. To get a login token, complete the Intake form. Scott will email you a token.
  2. In CarPrint Settings (Live → gear): turn on Upload trips and enter your access token.
  3. Now completed trips will upload automatically when you have network access.
  4. Sign in at getcarprint.com with the same token.
