Mike is an AI mechanic that lives in your phone. Plug a Bluetooth OBD2 adapter into your car and Mike reads your live engine data, pulls trouble codes, and explains what's going on like texting a mechanic who actually knows your exact car. No more copying a P0420 code into a search bar and panicking. Just ask Mike. WHAT MIKE DOES • Reads your check engine light: Mike pulls the diagnostic trouble codes (DTCs), tells you what they mean, how serious they are, and what to do next. • Watches live data: coolant temp, RPM, speed, battery voltage, fuel trims and more, streamed straight from your car. • Answers real question: "Why is my check engine light on?" "Is my car safe to drive?" "How's my battery doing?" Mike knows your make, model, and year, so the answers fit your car. • Runs a health check: a quick scan of codes, readiness monitors, and key sensors so you know where you stand before a road trip or a sale. • Remembers your car: every scan is saved, so Mike tracks your vehicle's history over time instead of starting from zero. HOW IT WORKS 1. Add your car (or scan your VIN). 2. Pair a standard ELM327-style Bluetooth OBD2 adapter: they're inexpensive and work on most cars built since 1996. 3. Ask Mike anything. WHY DRIVERS LOVE IT • Plain English, not error codes: Mike translates mechanic-speak into answers you can act on. • Catch problems early: spot a failing sensor or weak battery before it leaves you stranded. • Walk into the shop informed: know what's wrong (and roughly what it should cost) before anyone hands you an estimate. • Works on any car model: if it has an OBD2 port, Mike speaks its language. Whether you're a new driver who's never popped a hood, or someone who just wants a second opinion before paying for repairs, Mike turns the mystery light on your dash into a clear, honest answer. Download Mike and finally understand your car. Mike requires a Bluetooth OBD2 adapter (sold separately) to read live vehicle data. Compatible with most gasoline vehicles model year 1996 and newer.
