Battery health, individual cell voltages, charging telemetry, and CarPlay dashboards — straight from your vehicle's E-GMP platform to your iPhone.
TheIoniqGuy takes IONIQ 5 Companion for a full hands-on tour.
Connect an inexpensive ELM327 Bluetooth adapter and read your vehicle's live data — cleanly organized, charted, and recorded.
State of charge, available energy, cell voltages, pack temperatures, 12V, motor RPM, regen, tire pressures — a full live readout you can reorder to taste.
Live AC and DC charging detection, EVSE max voltage / current / power, Control Pilot duty cycle, and ICCU input voltage and current.
Individual battery-cell voltages and a per-sensor module-temperature grid with min, average, max, and delta — plus battery-temperature history charts.
Every charge and drive recorded automatically — peak power, energy, efficiency, full charts — and synced across your iPhone and iPad.
Live telemetry chips on your head unit while driving, a Status view when parked, and Charging and EVSE views that appear during a session.
DID range scans, an ECU finder, curated DID lists with tester sharing, and an Adapter Quiet Check — for owners who want to go deeper.
No need to look at your phone. The most important numbers live right on your vehicle's main display.
Compare what your vehicle asked for against what the charger actually delivered — and what the EVSE advertised it could do. Spot a bottlenecking charger instead of guessing.
A preconditioned battery accepts more power, so it climbs to 80% faster. This live ETA shows exactly when your pack reaches its ideal fast-charge temperature — so you time your arrival, charge at full speed, and spend less time at the plug.
Real screens from the app — dense data, organized so you can read it at a glance.
“Connection to my Veepeak adapter was instantaneous. The UI is very well done… clearly tuned for maximum info with minimum fuss on the Ioniq 5. The CarPlay interface is great too, providing near real-time at-a-glance information.”
“I have a 2023 Ioniq 5 and it works flawlessly. Very easy and quick to set up. I love how I can use it with Apple Car Play and have all the info displayed on my screen while driving.”
“This is a great App — no need to fuss around with the others that require a lot of configuration and are obviously built for ICE vehicles. Thank you to the dev.”
“I'm using it with a MY2024 AWD i6 and I can't find anything non-functional at first glance. Does the job, great stuff.”
“This app is incredible. Sooooo much nicer to use than the rest of the OBD reader apps out there. Thank you for making it!”
“I almost never write reviews for anything, but I wanted to take a moment to review this app. This is exactly what I've been looking for: instant set up, amazing data, very easy to understand visuals. I give this app 10 out of 10.”
Your car's data is sensitive. It stays on your device and in your own iCloud — never on our servers, because there are none.
Per-vehicle registries, decoded from each car's own modules.
The app talks to your car through an inexpensive OBD-II adapter. It just has to be Bluetooth Low Energy (BLE). These are tested and verified:
Buy once, own it. No subscriptions, no in-app purchases, no ads.
