Any ELM327-compatible Bluetooth OBD2 adapter works. We recommend a dual-mode or BLE model for the most stable connection. Avoid the cheapest clones — they often drop PIDs or disconnect mid-drive.

Most petrol and diesel vehicles built from 2001 (EU) or 1996 (US) onward have a standard OBD2 port. Which parameters are available varies by make, model and year — DriveSense auto-detects the PIDs your vehicle supports when you pair.

Yes. All telemetry, alerts, health scoring and anomaly detection run on-device from the adapter link, and your trip history is stored locally on your iPhone. An internet connection is only needed to purchase or validate a DriveSense Pro subscription.

Open the dashboard and tap the HUD toggle, then place your phone on the dash. Mirror mode flips the readout so it reflects correctly onto the windshield, with auto-brightness for day and night. HUD mode is part of DriveSense Pro. Set it up before you drive, and check that windshield displays are legal where you are.

If a parameter shows blank or 0, your vehicle or adapter most likely doesn't expose that PID. Try reconnecting — DriveSense re-scans supported parameters on every pairing. If a value that used to work has stopped, a cheap adapter dropping frames is the usual cause.

Turn the ignition on so the OBD2 port is powered, make sure Bluetooth is enabled in iOS Settings and that DriveSense has Bluetooth permission, then unplug and re-seat the adapter. If your adapter pairs through iOS Settings with a PIN, pair it there first, then reopen DriveSense.

No. OBD2 readings, your VIN and your trip history stay on your device — there is no account and no cloud sync. The full detail is in our Privacy Policy.

The core app is free: connecting to your adapter, the live dashboard and gauges, the health score, alerts, the trouble-code list, your last three drives and one vehicle in the garage. DriveSense Pro is an optional auto-renewable subscription that adds the full live data tab, code explanations and repair advice, the full health report, unlimited history, calibration, trip computer, acceleration test, HUD mode, the emissions check, multiple vehicles and CSV export.

Monthly or annual, with a 3-day free trial for new subscribers. Reference pricing is US $4.99 per month or $34.99 per year; in Türkiye ₺34,99 per month or ₺249 per year. The exact price for your region is always shown in your local currency before you confirm. Full details are in the Terms of Use.

On your iPhone open Settings → your name → Subscriptions, select DriveSense and tap Cancel — or go to apps.apple.com/account/subscriptions. Cancel at least 24 hours before the period ends to avoid the next renewal. Pro stays active until the end of the period you've already paid for. Deleting the app does not cancel the subscription.

Open the DriveSense Pro screen and tap Restore Purchases — this is also what to use on a new device or after reinstalling. Make sure you're signed in with the same Apple ID you purchased with. If it still doesn't unlock, email us and we'll sort it out.

Purchases go through the App Store, so refunds are handled by Apple at reportaproblem.apple.com. Tell us what went wrong too — if it's a bug on our side we want to fix it.
