Live gauges
- State of charge and real usable energy — not a guess-o-meter
- Pack voltage, current, and power
- Battery, motor, and ambient temperatures
- Tire pressures, all four corners
- 12V system health — the part that actually strands trucks

Your truck's real numbers, at a glance.
Big gauges for state of charge, usable energy, pack power, and temperatures — pulled live from the vehicle, drawn for a dash mount.

Everything the truck knows, made readable.

What you need
Two things. You already own one.
A Bluetooth OBD-II adapter
Any Bluetooth Low Energy OBD-II adapter that plugs into the port under the dash. The Vgate vLinker MC+ is the adapter ChargeState is tested with.
A Ford F-150 Lightning
ChargeState is built specifically for the Lightning's signals — its battery pack, its charging behavior, its quirks. It is not a generic scanner.
Privacy
Your truck's data never leaves your phone.
ChargeState has no accounts, no analytics, and no servers. Every reading, every drive, every charge session is stored on your phone and nowhere else. The app makes exactly one kind of network request: if you choose to send a support message from inside the app, it sends what you typed — and nothing more is ever transmitted, by anyone, for any reason.
The full policy is short enough to actually read: Privacy policy.
