Stallion

Stallion connects to your car over OBD-II to log trips, decode faults, track true cost of ownership, and keep recalls in view — local-first vehicle intelligence.

You drive. Stallion takes the notes — live OBD, decoded faults, true cost of ownership, automatic trips, and recall watching.

How it works

01 Connect — Pair an OBD adapter, or add vehicles by hand.
02 Watch — Live status, codes and costs land in one garage.
03 Act — Share, compare, schedule service — stay ahead of it.

Core capabilities

Live OBD — Plug in once. RPM, speed, fuel trim and coolant stream while you drive.
Faults, decoded — DTCs arrive as plain language with severity and a path to help — not hex codes.
True cost of ownership — Fuel, service and insurance roll into one number, so every car earns its keep.
Garages & sharing — Split personal and fleet spaces. Invite drivers by link — you stay the owner.
Trips that write themselves — Wheels turn, OBD armed, Stallion logs distance and context automatically.
Recalls, watched — Every VIN checked against NHTSA weekly. Campaigns shown word for word.

Your data

Your data stays on your phone — Stallion saves everything on your phone first, so it works with no signal. The cloud is only there to sync your devices.
Only you can see your data — The server checks who is asking before it hands anything back. That rule lives in the database itself, not just in the app.
Your login is locked away — Your login is kept in your device’s secure storage, never as plain text. Turn on two-step sign-in and a stolen password alone gets nobody in.
The AI only gets what it needs — AI questions go through our server, so no secret key sits inside the app. Your car details are sent only to answer your question. They are never sold.
You stay the owner — On Plus, Pro and Enterprise you can invite a driver. They can see the car but cannot take it over, and you can remove them any time.
Leave whenever you want — Delete your account and your data is really erased from our server, not just hidden. Pro and Enterprise can also export it to CSV first.
