EVPeek turns your iPhone into a trustworthy second instrument cluster for your electric car — and, where the car itself won't say, into an honest instrument for the battery underneath it. READS YOUR CAR, NOT A SERVER Tesla owners: connect over Bluetooth using your own phone key. No Tesla account, no password, nothing sent to anyone. Hyundai, Kia and Genesis owners: a Bluetooth OBD-II adapter reads the battery management system directly — state of health, cell balance, module temperatures, and the pack's own charge reading next to the one on your dash. Any other car: EVPeek still shows speed and logs your trips using your iPhone's sensors, and tells you plainly that's what it's doing. EVERY NUMBER SAYS WHERE IT CAME FROM Every reading carries its source and its age. Stale values dim. Values too old to trust are hidden rather than shown. Derived numbers show their working. EVPeek never displays a number it cannot explain. DRIVE MODE One number, enormous, on a true-black screen. Built and measured against a 1.2-second glance budget. Tap to switch between speed, range, charge or kWh remaining — your choice, not ours. DELIVERED VS BILLED EVPeek measures the energy that actually went into your battery, integrated from the pack's own voltage and current. Enter what the charger billed you and see the difference. When a charging network's number and your car's number disagree, you have evidence instead of an argument. EVIDENCE PDFs One tap turns a charging session or a drive into a timestamped document — charts, temperatures, and a statement of where every figure came from. Built for warranty claims and billing disputes. BATTERY HEALTH, HONESTLY State of health with a confidence band, an adjustable buffer multiplier, and a plain-language explanation of what was measured and what wasn't. EVPeek would rather show you a confidence interval than a confident lie. CHARGERS 56,000 DC fast-charging sites across 125 countries, bundled and working offline. Every one is coloured by whether your car, at its current charge, can actually reach it — and what you'd arrive with. EVERYWHERE YOU LOOK Widgets for every size, one per vehicle — a Tesla and an IONIQ 5 side by side on one Home Screen. Live Activities for any charger on any supported car. Apple Watch complications. A CarPlay Charging tab with live tiles. Control Center controls. Shortcuts. PRIVACY No analytics. No advertising SDKs. No third-party frameworks of any kind. Your trips, charges and battery readings stay on your iPhone. Your VIN is never stored. FREE FOREVER The live dashboard, Drive Mode, pack temperature, one vehicle, widgets, a Watch complication and seven days of history cost nothing and always will. EVPEEK PLUS Unlimited history, full battery health, delivered-vs-billed, evidence PDFs, every widget for every car, and export to CSV, JSON and GPX. EVPeek reads your car. It never locks, unlocks, starts or controls it. The only things it ever writes are the two you confirm yourself: adding your iPhone as a key to a Tesla, and clearing stored trouble codes from the Inspect screen.
