When was this app last update iOS. Keep up great work ### 1/5 — CarPlay? *2025-09-23* There's no CarPlay, which is bad, but Hondadata system is better **Developer response:** Why stupid 1 star review for a function that’s not possible and never existed in the app? This is so annoying ### 1/5 — CarPlay? *2025-05-06* Why is there no CarPlay? This is so annoying. **Developer response:** Why stupid 1 star review for a function that’s not possible and never existed in the app? This is so annoying ### 1/5 — No NeptuneRtp Option? *2025-04-19* I am not seeing the option for Neptune. Is it still supported? **Developer response:** OBD1 ECU’s not supported, because all the current Bluetooth modules are not compatible with iOS. I don’t understand why the 1 star review instead of asking this in email. ### 2/5 — Ok *2025-03-06* App worked great, then suddenly my IOS updated and now the app won’t connect. Hoping it gets fixed but going on a few months now since the update and nothing yet. ### 1/5 — Trash *2025-02-27* What a rip off.. paid for it and cant use it with my obd1 ecu burton racing data log… do not not purchase this rubbish **Developer response:** It’s stupid when you want to use it with a device that is not supported. Learn to read. Also if you don’t know how to read, how to request support or even do a refund that’s not our problem. ### 1/5 — Does not work on my iPhone 16 pro *2025-02-23* Will not connect to my ecu via Bluetooth. My ecu connects fine to the app on my friends android device but will not connect with the app on my phone. Would be grateful if this issue was fixed so I can use my phone to read my data **Developer response:** Contact support via email. If it’s a KTuner V1.2 device, you can find the info what requires to be able to use with iPhone ### 5/5 — Has a couple MINOR issues but overall, LOVE IT! *2025-02-11* I have the V2, Ive gotten soooo many compliments when I have V2 going, mounted to gauge cluster with suction cup adapter, and have my iPhone 16 Pro Plus maglocked to an attachment attached to my center vents with TunerView in the Gauge mode layout. Looks so sick at night with the V2 going and the gauge layout needles going, I changed the colors to be close to my stock cluster colors. Nice being able to set colors to change if something needs attention cause usually when you’re pushing the car you’re trying to stay focused on the road so I have my a/f, rpm, ect to turn red if it goes over a certain value. Please add some more layouts. Yes was a little frustrated when I tried to play music and it stops, but from what Ive read you just hit play again? This is for TunerView if you read it, I obv bought the app protocol for the V2 but recently in the gauge layout only 3 out of the 6 gauges will display anything. Trying to delete and reinstall app. Thank you, love the app, aldd more features please, is the navi layout with the perimeters around the navi layout only on android? Thanks! ### 1/5 — Doesn’t work with IOS *2025-02-08* Couldn’t connect V1.2 to Bluetooth, and app would infinitely say “connecting”. Was hoping this would work but it doesn’t. Forums online say you need an android platform. **Developer response:** Check KTuner Online help how to enable Bluetooth BLE on the KTuner. http://www.ktuner.com/KTunerHelp/v1_2_bluetooth_setup.htm ### 2/5 — Great app with a big problem *2025-02-01* This app is really nice to have but only because it’s the only viable option I can find that works with a ktuner. The biggest issue I have is whenever I do anything “outside” of the app like opening, closing, and bringing up control center, it pauses my music. This is EXTREMELY annoying as I use CarPlay and the app at the same time, all the time. I even emailed them and they said their’s nothing they can do about it when I know that’s not true. My car detects it as a microphone activating whenever this happens even though it shouldn’t be using the mic. Emphasis on shouldn’t, especially when I’m not using the camera feature. I also just wish it had more layouts, especially a track mode where it’ll show 0-60 and race track related things. Other than that it works as it should. **Developer response:** IOS can only connect Bluetooth devices that acts as a headset or audio so the KTuner device Bluetooth module was set this way. Because of that, iOS pauses the music, and not because of what you mention. If we set the KTuner different way, it will not work and you can’t see any data. ## Frequently asked questions about TunerView ### What does TunerView do?
