素晴らしいアプリ、オーナーは購入推奨

OBDからデータを取得してスマホでも車載モニターでも色々なデータを確認できるようになる凄いアプリ!
IONIQ5の弱点である12Vバッテリーの状態をいつでも見られるため、不安が解消されました。
ひとつだけ不満というか分からないことがあり、TPMSの項目で四輪ともほぼ同じ数値なのにRRだけオレンジ色になるのですが、ヘルプにオレンジ色になる条件などの記載がありません。説明を追加して頂けると助かります。

KONA(SX2)でも最低限の動作はします

car scanner proからの乗り換えです。obdの掴みも素早く、スタイリッシュでとても気に入ってます。開発してくださりありがとうございます。
当然、IONIQ5のように完全動作はしませんが、KONAも完全対応していただけると泣いて喜びます。

Great addition for nerds like me!

I am super interested in the tech in my Ioniq 5 and already had an ODB BLE dongle and Car Scanner. This purpose-built Ioniq focused app is just what I was really looking for! I had been trying to build my own dashboards in Car Scanner and this is *way* better. I am still exploring all the amazing features available in this app. Thank you for building it just for me! (Or so it feels like)

Great when working

I’m keeping my eye out for bug fixes. I have really high hopes for this app, but in its current state it’s too unstable.

There is an issue that causes CarPlay to completely stop functioning correctly - and not just for this app - all apps. No navigation, no music, nothing.

It didn’t affect me until the moment I was about to drive off on a roadtrip. When I restarted my phone I even needed to authenticate my apple account again.

I thought the restart fixed everything, but I happened again three more times over the next two days. Finally I deleted this app completely and things are back to normal.

I’ve seen others have this issue too and that the developer is aware and working on it, so again, I have high hopes this app will be great with time.

Response from developer

Hi theMITIGATOR: Thank you for the feedback, and I apologize for your inconvenience. For those reading, this is a known issue that is being addressed: after long periods of sustained activity (long drives, or frequent drives), a core iOS component known as CarPlayTemplateUIHost can get into a bad state. When this happens, the information on the CarPlay screen is replaced by default musical note icons -- hence the name "the music notes bug". Normal operation is restored by rebooting your iPhone which restarts CarPlayTemplateUIHost. I am working on a permanent fix for this bug which will appear in the next version. The issue is being tracked on the support site (issue #33). If you tag yourself on that ticket, you will be notified as progress is made. If you would like to test out a beta version sooner, please send me an email (address on the support site) and I would be glad to add you to the beta test pool.

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.

Nice app but nonsense rpm

Further to the below the developer clarified that rpm refers to motor rpm not wheel. My mistake, thanks for clarifying:

My ioniq5 displays circa 6000rpm at 50mph, it has a wheel diameter of 28”. The rpm is wrong. 6000rpm would be 8.33 miles per minute or 500mph! So a factor of 10 out. Or is this intensional, or my math wrong?

Response from developer

Hello jwDaveR! Thanks for the careful math — you're right that 6,000 wheel RPM would be about 500 mph. The gauge shows motor RPM, not wheel RPM. The IONIQ 5 has a single-speed reduction gear of roughly 10.65:1 between the motor and the wheels, so at 50 mph your wheels turn about 600 rpm and the motor turns about 6,400 rpm — which is exactly what you saw. The reading is correct; in the iPhone app, they are labeled "Motor (rpm)" on the gauge to distinguish it from road speed, but in CarPlay I try to keep everything cleaner and simpler (glanceable) -- I'll think about changing this to avoid this sort of confusion in the future.

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.

Response from developer

Hi Cheule, thank you for the kind review despite running into that difficulty with onboarding. I'm exploring what I can do on my side to make that a smoother onboarding experience for people who use more than one OBD-II app. One tip: Make sure you don't have another OBD-II app running along with IONIQ 5 Companion at the same time. This can lead to a degraded experience for all of the running apps. Sometimes when apps are in the background you can lose track of the fact they are talking with the adapter. I'm adding a diagnostic check to help people identify when other OBD-II apps are communicating with the adapter at the same time. Thanks again!

Fantastic App

Finally a CarPlay app with rich telemetry data laid out in a nice way. Don’t be fooled by the app name. Works great with my MY23 Kia EV6 GT and gives me the technical info right where I want it.

The phone app side allows you to drill into the fine detail and really exposes the info that Hyundai group cars should be offering by default in their cars.

Works with ev5

Just tried it with my EV5 seems to work fine well done to the developer. Reports the correct number of temperature modules or whatever it is and the number of battery cells.

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.

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.

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.

Impressed - give it a try

Easy set up- impressive display on CarPlay- good history files. Much better than MyHyundai

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.

Response from developer

Hi Ba bb boo eee - that is a great suggestion. I'm going to add this into a future build. Thanks for the constructive feedback, and don't hesitate to reach out via the support email anytime if you have other suggestions -- this app is heavily influenced by community involvement. Thanks again!

Looks to be useful

I’ve gone 4 stars as it’s not perfect but initial thoughts are good. The power meter display I’ve got set to BHP but it’s quite a slow response time. Is there a way of increasing the refresh rate?
Also for future, any chance of a track page with just track/performance relevant info? That would be awesome.

Response from developer

Hi Andy, Thank you for the constructive feedback, and that is a fair observation. IONIQ 5 Companion divides up the available bandwidth with the OBD-II adapter into polling slots. It is designed to work reliably across a wide array of generic OBD-II adapters, a wide range of vehicles, and varying environmental conditions (lots of BLE traffic). I would also like a faster refresh rate -- real-time would be fantastic! I have heard from a few enthusiasts who would like a track page with performance data, and I have added that in the feature roadmap. Please feel free to visit the support site and make note of any features you'd like to see added - this app has largely grown from the input of the community. Thank you again! Greg

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.

12V

Didn’t know the OBD reading can only connect to one app at the time. After disconnecting the other app , the did work display everything

Response from developer

Hello Sun man, I am sorry to hear that you had an issue reading 12V SoC. That is a supported feature in IONIQ 5 Companion. It would be my pleasure to work with you to resolve your issue. Please send me an email on the support web site -- I am certain we will figure this out. Thanks and best regards, Greg

Amazing EV App

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