  Hard 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.

  Fully replaced Car Scanner

  This is built ground-up for the eGMP platform cars (Ioniq 5/6/9, Kia EV6/9, 5 N and GT) —and it shows. The CarPlay display is gorgeous! But the in app displays are even better. There is now logging and exporting to CSVs, this app is deep and well designed. 100% worth buying if you own an Ioniq or Kia EV.

  An essential for Kia/Hyundai owners

  I normally do not write reviews but I figured I must here. This is a stable and well coded display of ODB2 data specific to EV. Kudos to the dev.

• ★★★★★Pique

  Be Aware - this needs a Bluetooth ELM327-compliant OBDII Scanner

  My old OBDII scanner was WiFi only, so it was not usable with this app. Be sure to read the developer’s helpful instructions carefully to ensure compatibility with your equipment.

• ★★★★★Ssjsusjbeidbeueiwhejd

  Must have app, I would give it more stars if possible

  Tons of useful and just cool information, very nice display, explanations helped understand the car better. And on top,the developer replied with answers to my questions in a few hours.

• ★★★★★Ba ba boo eee

  Level 2 charging plug temp needed.

  Level 2 charging plug temp(VCMS AC INLET) display desperately needed displayed on the charging screen. You can even put this in place of the tire temperature read out which is not needed during charging.

  A Must Have for Stats Nerds

  2025 Ioniq 5 SEL As advertised, this app gives you all the crunchy details the car hides by default. Very cool to see exactly how the car performs while driving and charging, and the history feature is really nice as well. MyHyundai only saves stats for the last 4 drives, but this app has no such limit. It’s also nice to see specific details for my ICCU unit, and high voltage cell deltas to assess any issues. Highly recommended.

  Amazing EV App

  Great app as a first time EV owner, lots of information and useful tools.

• ★★★★★ThinkFlight

  Good to have, still need some tweaks

  I agree with the ionic guy, this should be essential if you own an ionic five. To the developer: please take a closer look at the tire pressure colors displayed by default. If I have my tires properly inflated to cold temperatures once they warm up, they show is orange instead of green. This is what I would consider an incorrect behavior. I believe the software should be able to take this into account as that’s what the manufacturer recommends cold pressure to be sent to. If you go to any Costco or tire shop in the US, they will normally set the tires to +3 or +4 psi from label on the door panel for warm tire inflation if you’ve driven more than half a mile. The vehicle should know what a warm tire is versus a cold tire. If you could somehow adjust the software to take this into account, that would be great. As is right now if it goes above 36 psi it always shows orange even if that is normal behavior of a tire set to 36 cold as the #DATA placard and the manual states. I picked this app up after seeing a YouTube review from “the ionic guy” that does a good showcase on the software. I recommend anybody thinking about it. Take a look at that video.

  I’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.
