## What is ActiveOBD?

The OBDII scanner app with a special support of Subaru (MY2012+) make. It's the next-generation product based on our well-known "ActiveOBD for Subaru" app bringing its best features to iOS users. A compatible OBD adapter is required.

Premium-level adapters supported (best speed and stability):
- OBDLink MX+;
- OBDLink CX;
- vLinker MC+.
Entry-level adapters supported (moderate speed, good stability):
- Vgate iCar Pro Bluetooth 4.0 (BLE).
Other adapters supported:
- Viecar Bluetooth 4.0 (BLE), Vgate iCar Pro WiFi, Veepeak OBDCheck BLE+, KONNWEI.

We do NOT support the majority of cheap ELM327 v2.1 clones.

The basic free version already includes CVT Oil Temperature, CVT ratio and AWD duty (%) parameter readings and nice gauge screen ! Note: some of these parameters are inaccessible on some model ranges.

The full version (subscription) includes extra parameters reading and features, such as graphs building, logging ("premium-level adapter" required), trouble codes reading.
Note: for resource consumption optimization reason the data collection for graphs/logging activates upon accessing these functions and terminates with the current app session.

### 1/5 — Disappointed

*2026-04-30, version 1.5.1*

The only gauge I get is coolant temperature. This app was recommended because it supposedly will display transmission temperature which is what I needed. All is get is coolant temp so there’s obviously something wrong with the app. Pretty useless. I subscribed, thankfully there’s a 1 month free trial so I won’t lose any money. Definitely unsubscribing and deleting the app.

### 1/5 — Only one gauge option, will not display anything besides battery

*2026-04-05, version 1.5.1*

Refer to title

### 3/5 — Keeps disconnecting ELM327 WiFi

*2025-12-20, version 1.5.1*

Connection is not stable. More like a cache/variable byte size issue.

### 5/5 — Perfect!

*2025-07-31, version 1.5.1*

App works great for monitoring all of what I can’t see on my 2020 Subaru Forester Sport!

### 4/5 — CVT Fluid Temp

*2025-06-02, version 1.5.1*

This app is good for reading your CVT temp in your Subaru and a few other gauges, but it is not as in depth as the android version which includes more. It would be nice to see the same gauges that the android version has, specifically the CVTF Condition % gauge. That being said solid.

### 4/5 — Nice app for Subaru

*2025-03-02, version 1.4.2*

Using app with Vgate iCar Pro 4.0 allows me to monitor CVT temp while towing with 2019 Crosstrek.

App is very easy to use.  It could use some enhancements but not deal breakers (like when setting up the screen you need to go 3 dots, edit, add the sensor.  Then instead of allowing you to add another it takes you back to the main screen with the readouts.  Then to add another you need to 3 dots, edit etc… not a deal breaker and your not doing that every day so it’s really only a pain once)

Only reason gave it 4 stars is lack of CarPlay.  It would be great to see on car’s screen.  Not sure if that is an Apple or developer limitation.

### 3/5 — Very useful but…

*2024-10-21*

I am using this app with an OBDLink MX+ and it displays the most useful information for me as I have done a transmission repair and I wanted to make sure the transmission is not overheating. Although I think 4.99 per month is too much for it, I would gladly pay a one time fee, the problem is that the app has the following problems 
1) It freezes sometimes for no reason while driving and displaying the app and will not reconnect unless I disconnect the Bluetooth and reconnect it.
2) It freezes every time I switch to another app and then go back to this. At that time, just like in case #1, I have to go to Bluetooth settings, disconnect the phone from the device and then reconnect it. Then I can open the app and Connect.

These problems do not exist for the app that comes with the OBDLink MX+. 

Please fix the freezing issues and then I will pay for the subscription.

### 2/5 — Kiwi support

*2024-04-10, version 1.4.2*

Still waiting on the developers reply to my previous review inquiring about Kiwi 3 Bluetooth support. The release notes from 3 years ago state that this app added support for Bluetooth LE OBD readers. Kiwi uses BLE 4.1 which IS supported by other major OBD apps for iOS. Why exclude support for this app developer?

### 1/5 — NOT working with OBDLink MX+???

*2024-02-13, version 1.4.2*

NOT working with OBDLink MX+??? Wanted to purchase as I have a 2019 Subaru Outback and like to get CVT temps. I guess we’ll never know. 

Complete failure on Developers part as request for OBDLink MX+ support was requested on a review from TWO YEARS AGO!!!

### 2/5 — Needs Kiwi 3 support

*2023-12-28*

Why does this not support Kiwi 3 for iOS? 

Kiwi 3 is Bluetooth 4.1 LE
