### 3/5 — Impossible de me connecter sur mon iPhone,adaptateur ( icar pro Bluetooth)

*2025-11-27*

Bonjour, j’ai essayé pas tous les moyens de connecter mon ICAR pro vgate sur l’application impossible je vous ai envoyé un mail depuis un moment j’ai pas de réponse de votre part  «application payer »

### 3/5 — Needs Metric setting

*2025-08-23*

Visually good app. For those that don’t live in the US it would be nice to be able to change from miles to kilometres, can be done manually with a toggle in settings or check the phones region settings on launch. Maybe even allow users to choose which measurement for individual ones like speed, pressure, etc.

**Developer response:** Hi there,

You can change units of measure for all applicable Pids from app settings -> Gauge graph settings -> Sensors. You can also modify pids units of measure by long pressing on a gauge in dashboards and selecting sensor details.

### 1/5 — Crashes in CarPlay with battery gauge – no refund offered.

*2025-08-16*

I purchased this app for CarPlay gauge display, but it crashes every time I add the battery gauge. I reinstalled multiple times and confirmed the issue is not my car or OBD adapter (another OBD app works perfectly in CarPlay with the same setup). I requested a refund through Apple, but it was denied. Be aware that this app does not work reliably and support was no help and Apple support would not budge for a refund.  Both this app, and Apple support are horrible.  Don’t buy it, you will be out the money.  Worst experience ever.

### 1/5 — Crashes on open.

*2025-06-30, version 1.5.3*

Useless

### 5/5 — Crashes on diagnostics trouble codes

*2025-04-24, version 1.4.7*

Updated Bluetooth device Icar pro vgate + dodge Ram 2010 fyi and crashes on trouble codes.

### 2/5 — Funktioniert nicht

*2025-03-04*

Die App versucht sich mit dem adaptier zu verbinden und stürzt ab. Egal ob das Fahrzeug steht mit Zündung an und aus ist . Bei der Fahrt geht sie auch nicht.

**Developer response:** Entschuldigen Sie die Unannehmlichkeiten, aber die App wurde nicht mit jedem OBD-Scanner getestet. Deaktivieren Sie Fast Polling und PID-Scan in den Verbindungsoptionen. Wenn Sie immer noch Abstürze haben, setzen Sie sich mit mir in Verbindung. support@shiftobd.com

### 3/5 — Bugged

*2025-03-03, version 1.4.3*

App crashes when you try to go to trouble codes the only reason I bought this app for

### 3/5 — Well put together but lacks a important feature.

*2024-09-30, version 1.3.9*

Good app & developer has put in a lot of work. However, this app is designed to be used in your car but it doesn’t support CarPlay. 

Almost all the competitors have CarPlay support. Hopefully one day this app will catch up & deliver.

### 1/5 — Obd connect

*2024-07-01*

Can’t get to work

**Developer response:** Please explain. support@shiftobd.com

### 4/5 — Nice app

*2024-06-13, version 1.3.8*
