Canceling a recurring subscription stops future renewal; access continues through the paid term. Prepaid licenses have no automatic renewal to cancel.

No. An active bundle entitlement covers its included plan; you do not need an additional app-store subscription for the same coverage.

Activating a license does not cancel existing billing. Check your active coverage and receipts before canceling any recurring subscription you no longer want through its billing store. A prepaid license does not itself create recurring charges.

OBDAI works with most OBD-equipped passenger vehicles, but exact coverage depends on market, model year, protocol, and the data each vehicle exposes. Some 2025 and 2026 vehicles already use SAE J1979-2 OBDonUDS; that path requires OBDAI 2.7 or later, GEN2, and PRO.

Your Premium bundle includes:

• OBD2 Bluetooth adapter (Gen 1 or Gen 2 depending on your order)

Your license code is emailed immediately after purchase — so you can start using Premium right away, even before the hardware arrives. Amazon orders also include a physical license sticker on the packaging.

For setup instructions, see our Getting Started guide.

Three steps:

1. Download OBDAI and sign in
2. On Android or Windows, open the menu, choose Upgrade, then “Yes, I have a code”
3. On iPhone or iPad, activate through obdai.app/quickstart because Apple does not allow in-app code entry

Your Premium access activates immediately across all your devices.

Full setup guide →

Yes — all of them. Sign in with the same account on your phone, tablet, and laptop. Premium syncs automatically across iOS, Android, and Windows.

One purchase. Every device you own.

Yes. The license code can be activated by anyone on their own device. Just give them the code — they redeem it, they get Premium.

This makes OBDAI bundles ideal for gifts, or for businesses purchasing codes for employees or fleet vehicles.
