1. 5/5Ultimate Ioniq 5 owner tool

   I’ve just started using this app but wanted to provide my initial impressions. Connection to my Veepeak adapter was instantaneous. The UI is very well done, with everything presented in an easy to understand format. I like the graphical representation of the items and how everything is well organized. The information presented is above and beyond what is normally available and, while most might be accessible through other apps, this is clearly tuned for maximum info with minimum fuss on the Ioniq 5. The CarPlay interface is great too, providing near real-time (probably only limited by transmission from the adapter) at-a-glance information for much of the most critical information while either driving or charging. It’s obvious a lot of thought went into designing this app. I can’t wait to see what other enhancements the developer has in mind.

2. 5/5I’d Give 10 Stars For Greg’s Customer Service If It Was Allowed

   After reading the reviews on here and on Reddit I decided to go ahead and spend the money for this app to use with my Ioniq 6. I wasn’t able to get it to sync with my Veepeak OBD2BLE adapter, even though it was on the list of adapters that are compatible. I did all the usual steps with no luck. I emailed support (Greg, himself) and explained my situation. He got back to me within a half hour and gave me his phone number to call so we could troubleshoot the problem…on a Sunday…in the summer. I sent a screen cap of the message I was getting and he hadn’t seen that one before. But he walked me through several steps and eventually asked me to confirm, in the app settings, that Bluetooth was enabled. It was enabled in the general settings but It wasn’t in the app itself (for some reason). Issue solved. The app fired right up. And I spent the next hour plus geeking out over the inner workings of my I6. Goodbye Car Scanner. Hello Ioniq 5 Companion. It’s well worth the $13. Thanks Greg. I hope you make a lot of money with this app.

3. 3/5Hard to read

   Overall I love the concept of this app. The information is fantastic. It provides far greater insight into what’s happening with your vehicle than the standard displays. The only issue I have is with the car play display. If you use a spot screen to display other information, like the radio station, then the information icons for this app become too small to read. It’s just easier to read the phone. Unfortunately on the phone you need to scroll to get the pertinent information. There’s far mor information available on the phone but the key stats are not collected together like they are on the CarPlay display. It was clearly designed to display without the split screen but it’s a common setup so I’m disappointed there isn’t an easy work around, like eliminating one or 2 icons to get them to fit on the screen in the larger format.

4. 5/5A MUST HAVE for every Hyundai/Genesis/KIA EV owner

   Even if your model is listed as under development GET THIS! It provides a second dashboard via CarPlay with all the data you couldn’t see before. Charging status, trip data, ICCU (our Achilles heel) information. Battery details for both 12v and the main batteries. Preconditioning and battery temperature status. All in a more digestible format than apps like Car Scanner. Developer seems very responsive to feedback and is actively improving the app

5. 5/5Great support

   I ran into a problem with connecting. Turned out to be the ABRP wasn’t letting go of the OBD-II scanner even after a reboot of the phone. The developer walked me through unlinking ABRP from the scanner when not using live data and the connection issue is resolved. Yeah, the problem wasn’t the app, it was me. The support for this app was great and I recommend giving it a try, especially if you like data about your car. For those Kia drivers, I’m driving a 2025 Kia EV6 GTL.

  Version 1.1 — broader vehicle coverage, deeper 12V insight, and a smoother first launch. CarPlay - New Tires chip on the Driving tab: pressure and temperature for all four corners - 12V chip expanded: state of charge, voltage, and current shown together with the same charging/discharging sign convention as the HV pack. Auxiliary (12V) battery - New collapsible 12V panel on the Dashboard: SoC, voltage, current, temperature — plus DC-DC converter temperature, output voltage, output current, and HV pack input voltage. Headlights — 2025 and 2026 IONIQ 5 - Low-beam and high-beam indicators now light up for the 2025 IONIQ 5 and the 2026 IONIQ 5. Added vehicle coverage - IONIQ 5 N — added decoding and registry coverage. - IONIQ 6 model year 2023 (RWD LR and AWD LR) Smoother onboarding - If your iPhone already has an OBD-II adapter connected through another app, the Welcome screen now offers a one-tap shortcut to use it - A swipe-to-confirm reminder explains that OBD-II adapters can only talk to one app at a time, so adopting an adapter is a deliberate choice Brake Light Indicator — your choice - Settings → Dashboard now offers three modes: Off, Red Background (enhanced gradient effect), and Red Text (the new default — only the ON/OFF turns red, or no brake tile at all. Reassurance on a common Hyundai code - A J1979 scan on virtually every Hyundai EV reports a permanent code, P0C17, on the drive motor controller. It's a self-test artifact, not a real fault. When the app sees it in the permanent slot after a scan, it now shows a brief explanation of why it's normal, when it would actually warrant attention, and a "Don't show this again" option. Tools for power users and testers - Adapter Quiet Check (Settings → Diagnostics) listens silently for 60 seconds for any other app talking to your adapter — a one-tap yes/no when you suspect interference is degrading scans. - Curated Scan workflow streamlined end-to-end: shareable .iqlist files, an A/B/C capture checklist for hunting new signals, in-app Quick Look preview when you receive a list from another tester, and a single tap to import. - Complete ECU Scan reliability improved on clone adapters that need a little more settle time after large multi-frame batches. Polish - Motor RPM gauges restyled with a thicker arc and the unit moved to the label, so the value sits as the single focal point. - Auxiliary SoC mini-gauge stays size-stable at larger Dynamic Type settings. - CarPlay battery row chips visually unified with consistent dividers, fonts, and tile geometry. - VLink-branded adapters now appear in the scan list without removing the name filter. - Numerous additional fixes across navigation, sheet presentation, localization of CarPlay chip titles, and Advanced Diagnostics tool naming.

CarPlay - New Power chip: a bidirectional gauge showing power draw and regeneration on one dial. - New Compass chip with a heading-up rose, and the option to show it in place of the odometer on the Driving tab. - DC fast charging shows three live readings side by side: power Requested, power Supplied at the inlet, and power reaching the Pack. - AC Draw chip shows live volts, amps, and kW while AC charging. - Cell Voltage Δ chip: a mini heatmap of every cell, color-coded by how far it sits from the pack average. - Experimental split-screen layout for the IONIQ 5 head unit. - New setting to jump straight to the Driving tab when your adapter connects.

Connection & adapters - Take manual control: connect and disconnect on demand, and turn Auto-Connect on or off — making it easy to share one OBD-II adapter between apps. Settings - New Keep Screen Awake control: choose whether the app keeps the screen alive while it's in the foreground. - Choose your Power units: kW, HP, or PS. - Choose your Efficiency units: mi/kWh, km/kWh, kWh/100km, or Wh/mi.
