A driver-first app for the 290 million Americans who own a car and have no idea what it's saying. Diagnose problems, plan maintenance, and stop overpaying mechanics — from your phone.
Cars are computers. Mechanics know that. Drivers don't.
"I just got a car. I want to know what I'll spend, what to upgrade, and what's coming up."
"I'm at 87k miles. What does the manual say I need? What's actually optional?"
"A light came on. Is this a $50 fix or a $5,000 one? Can I even drive home?"
Everything from translating fault codes to pointing you at the right replacement part — without making you read a service manual first.
P0420 means "your catalytic converter is underperforming." Not P0420.
Snap a photo of the problem. The app identifies it and walks you through the fix.
RPM, fuel, coolant, battery, and 100+ sensor streams the second you're connected.
Automatic service intervals based on your car's actual mileage. No more guessing when oil changes are due.
Every dollar your car has cost you, year by year. Decide when it's no longer worth keeping.
Need a new air filter? We'll tell you which one fits, where to buy it, and how to install it yourself.
Mobilem8 works on its own from day one. Add the OBD3 hardware when you want continuous, predictive monitoring instead of point-in-time checks.
The hardware is the difference between a smoke detector and a fire alarm. Plug it in once, leave it in. From then on:
Background data collection — no app open required.
Battery degrading over weeks. Fuel trims drifting. Intermittent misfires.
"Battery voltage dropping over 10 days → likely aging"
Cell imbalance, charging efficiency, thermal data.
iPhone first. Android and macOS in development.
Pair the device once. The app handles the rest.
Any 1996 or newer vehicle. That covers every car legally sold in the U.S. for the last 30 years.
No. The app works on its own with manual entry, and pairs with any Bluetooth OBD2 scanner you already own. OBD3 is what unlocks always-on monitoring and predictions.
iPhone first. Android and macOS are in development.
Your vehicle data stays on your phone unless you explicitly sync. We never sell your driving data, location, or vehicle info. Ever.
No. Reading data through the OBD port is exactly what mechanics and emissions inspection stations do every day.
That's the whole point. Mobilem8 is built for drivers, not technicians.
