Pick your vehicle once and CarIQ surfaces the codes that actually apply to it. FREE, ALWAYS: β€’ Full code search across the entire catalog β€’ Code title, category, and urgency at a glance β€’ Plain-language description of what the code means β€’ Save favorites and keep a history of recently viewed codes UNLOCK WITH OBD EXPERT PRO: β€’ Possible causes behind the code β€’ Typical symptoms to watch for β€’ Estimated repair cost ranges β€’ On-device AI explanations powered by Apple Intelligence, tailored to the specific code No obligation to guess, no waiting for a shop appointment just to find out what a code means. CarIQ helps you walk into the conversation informed β€” 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 β€” 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 β€” exact pricing is shown in the App Store before you buy.
