CarIQ helps you walk into the conversation informed — whether you're doing your own wrenching or deciding if it's worth a trip to the mechanic. Everything runs on your device. AI explanations use Apple Intelligence on-device processing — nothing is sent to a server. CarIQ is not a replacement for a certified mechanic's diagnosis. Repair cost estimates are general guidance, not a quote. OBD EXPERT PRO SUBSCRIPTION: OBD Expert Pro unlocks possible causes, symptoms, repair cost estimates, and on-device AI explanations. Choose Monthly, Annual, or Lifetime at checkout — exact pricing is shown in the App Store before you buy. Monthly and Annual are auto-renewing subscriptions: payment is charged to your Apple ID at confirmation of purchase, and each subscription renews automatically within 24 hours before the end of the current period unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel anytime in your Apple ID Account Settings. Lifetime is a one-time, non-renewing purchase.
