Range, at a glance
Charge level, estimated range and time-to-full as the first thing you see — not four taps deep. Charging cars roll the number like an odometer.
For the Mustang Mach-E
Your Mach-E,
without the wait.
Range, lock, unlock and cabin preconditioning — on the first screen and on your home screen. Voltpony is a companion to FordPass, built for the five things you do every day.

What it does
The things you actually do daily
Not a reimplementation of FordPass. A short list, done quickly.
Lock, unlock, precondition
The three commands you actually use, on the home screen and on a home-screen widget. Unlock asks for confirmation by default; turn that off if it annoys you.
Your car, your colour
Pick from the factory Mach-E paints and the hero art matches. Name your car, set your own avatar, choose from five themes.
Last known location
Where you parked, on a map, without opening a second app. Handy in a garage you didn't choose.
Chargers and dealers
A charging map filtered to connectors a Mach-E can actually use, plus nearby dealers when something needs a human.
Widgets that do things
Lock and preconditioning run straight from the widget. No launching the app, no waiting for a splash screen.
Be honest about it
Keep FordPass installed
Voltpony is deliberately not a replacement. Some things only the official app can do, and pretending otherwise would just waste your time.
Voltpony is better at
- Seeing range and charge state instantly
- Lock, unlock and preconditioning in one tap
- Home-screen widgets that actually run commands
- Finding a charger your car can use
- Looking the way you want it to look
FordPass is required for
- Frunk and trunk release
- Anything to do with your Ford account or billing
- Service scheduling and recall notices
- Vehicle software updates
- Adding or removing authorised drivers
The app has a one-tap hand-off to FordPass so the gap costs you a tap rather than a hunt through your home screen.
Security
There is no server to breach
The most useful security property Voltpony has is architectural: I don't run any infrastructure, so there is no database of yours for anyone to steal — including me.
Your sign-in stays on Ford's page
You sign in on Ford's own website inside a system-provided browser sheet. The app never sees, handles or stores your Ford password.
Credentials live in the Secure Enclave-backed Keychain
Access is stored in the iOS Keychain, marked device-only — so it is deliberately excluded from iCloud and iTunes backups. Restoring your backup onto another phone does not hand that phone your car.
Nothing is collected
No analytics SDK, no crash reporting service, no advertising identifier, no third-party dependencies in the app at all. Your VIN, your location and your driving stay on your device.
It rate-limits itself
The app enforces its own request budget, backs off after repeated failures instead of retrying into a wall, and refuses to fire the same command twice in quick succession — all to keep your account's traffic looking unremarkable.
Deliberately not documented here: endpoints, identifiers and the specifics of the token exchange. If you're a security researcher with something to report, the support page has a contact address and I'd genuinely like to hear from you.
Early access
Join the beta
Voltpony is in TestFlight while it earns trust. Before you join, please read this — it's the single most important thing on this site.
Use a secondary Ford account
Ford has locked accounts for unofficial API use. Create a separate FordPass account, add it to your Mach-E as a driver in the official app, and sign in to Voltpony with that account — not the login your vehicle ownership, warranty and service history are attached to.
Don't use a “+” address such as you+ford@gmail.com; those have been auto-flagged as disposable. Voltpony rate-limits itself to keep your traffic unremarkable, but it cannot make this risk zero.

You'll need the TestFlight app from Apple. Beta builds expire every 90 days — you'll get a prompt to update.
FAQ
The questions everyone asks
Is this coming to Android?
Not yet, and I won't pretend otherwise. Voltpony is a native SwiftUI app, so an Android version means writing it again rather than porting it. It's on my list, but it's honestly gated on how much interest the iOS beta gets. If you want it, say so on the support page — that's the signal I'll go on.
Will I get banned for using this?
It's a real risk and you should take it seriously. Ford has locked accounts for unofficial API use — both for very high request volumes and for traffic they simply judged anomalous. That's exactly why Voltpony tells you to sign in with a secondary Ford account added to your car as a driver, and why it rate-limits itself hard. It cannot make the risk zero. Nobody can.
Why a second account? That sounds like a hassle.
Because if an account does get flagged, you want it to be a throwaway rather than the login your vehicle ownership, warranty and service history hang off. Making a second FordPass account and adding it as a driver takes about five minutes. Avoid “+” addressing like you+ford@gmail.com — those were auto-flagged as disposable in a documented 2023 wave.
Does Voltpony have a server? Who sees my data?
There is no Voltpony server. The app talks to Ford directly from your phone, and your credentials and vehicle data never touch any infrastructure of mine — because there isn't any. I could not read your car's location if I wanted to.
Why can't it open the frunk or trunk?
Those commands aren't exposed to third-party integrations at all — not to Voltpony, and not to any other unofficial app. That's a Ford-side limitation, not something I can work around. The app has a one-tap hand-off to FordPass for exactly this reason.
Could Ford break this overnight?
Yes, and you should assume it will happen eventually. Voltpony depends on interfaces Ford operates for its own app and has never published or promised to anyone. Ford can change, restrict or shut them off at any time, without warning and without owing anybody notice — and if they do, some features or the entire app stop working until I can adapt, if adapting is even possible. This isn't a hypothetical: it's the normal life cycle of every unofficial integration. Please don't buy anything, or rely on this app for anything that matters, on the assumption it will keep working.
Which vehicles work?
It's built and tested against a 2023 Mustang Mach-E. Other Mach-E model years are very likely fine. Other Ford EVs may partly work since they share the same API, but I can't test them and I'm not claiming support.
What does it cost?
Nothing. There's no subscription, no ads, no analytics SDK and no data to sell. It's a thing I built because I wanted it on my own phone.
Is it open source?
Not currently. Publishing the client in full would mostly serve as a how-to for hammering Ford's API, which is the fastest way to get everyone's accounts flagged. Ask me on the support page if you have a specific reason to want it.
