### 2/5 — Waste

*2026-08-24*

I have used this app for quite a while now and recent updates means I have to pay now just to use basic functions so I will not be using again

**Developer response:** The FREE version has no additional functionality limitations; all features available in the previous version of the app are still available after the update. If you have access issues or can't find the feature you need, please contact us directly through the app (i) - Contact us and specify the issue. We'll investigate the issue.

### 2/5 — Stop pushing your adapter

*2026-07-17*

This is a pretty good app, but you can’t connect without the app shoving a new adapter in your face. I HAVE AN ADAPTER. Sure, offer your option once but never again.

**Developer response:** If you have any questions or problems, please get in touch with us directly from the app: Home Screen - Information - Contact Us, and be sure to describe your issue in more detail.

### 3/5 — Ok

*2026-05-17, version 3.0.6*

Works fine when it connects but it has trouble doing so

### 2/5 — Is anyone maintaining this app?

*2026-01-20*

Well, I can’t give it one star because it has got me through several issues. I just get really frustrated when I’m unable to connect to my OBDII reader. I can connect to the OBDII reader’s Wi-Fi through my phone settings just fine, but when I open the app, it’s very difficult to establish a connection.

### 4/5 — Much improved and good enough for me

*2026-01-17, version 3.0.2*

Tried using this 5 years ago in iOS but it wasn't compatible with my cheap obdii dongle. Now it seems to work great and I may not need to go back to using an Android device to work with said dongle

The free version is adequate for reading and clearing standard odbii codes and basic ecu engine statistics, etc.

### 3/5 — Backwards Step!

*2024-10-24*

Latest update has removed all my car pictures and you cannot update within the App. Completely pointless.

### 4/5 — Cant connect to wifi

*2024-09-30*

Previously was working fine. Until now it wont connect to the wifi odb2 even though i can see the wifi name on my phone

### 4/5 — Great OBD2 Scanner!

*2024-08-08*

I have been using the inCarDoc OBD2 ELM327 Scanner for a while now, and I must say it is a fantastic tool! 🔧 This app gives me detailed insights into my car's performance and helps me keep track of maintenance schedules. Highly recọmmend it to all car enthusiasts!

### 1/5 — impossible de mettre un vehicule

*2024-05-26*

L’application est vraiment obsolète. Je passe mon chemin.

### 2/5 — Ne fonctionne plus

*2023-08-28*

Très bonne appli qui marchait très bien ! A présent de marche plus, l'application me renvois vers les paramètres pour accéder au réseaux local, qui est déjà coché, m.a.j. ne règle pas pour le moment

### 2/5 — Update removed data!!

*2023-04-24*

I used this app for the $06 mode to determine my misfires and O2 sensor counts. now that it’s gone, this app is no better than ecutek. i paid for premium ages ago, bring back $06!!!

### 1/5 — Application en russe impossible de changer la langue

*2022-07-27*

Téléchargement sur plusieurs iphone pour tenter de traduire l’interface afin de savoir comment on change la langue : impossible de savoir où si on ne lit pas le russe ! Rien dans la documentation. Les tutos sur YT ne m’ont pas plus aidé. Après avoir perdu 1h, je désinstalle et je vais opter pour une autre app. Tant pis !

### 1/5 — Tá na hora de Atualizar urgente

### 1/5 — Bluetooth not available

### 1/5 — Won’t connect after update

*2026-08-19*

Worked fine until the recent update. All lights working on WiFi dongle no issues with the dongle. I did email PNN the log and description no response.

**Developer response:** If you have any questions or problems, please get in touch with us directly from the app: Home Screen - Information - Contact Us, and be sure to describe your issue in more detail.

### 1/5 — Get rid of it

*2026-08-10*

This OBD 2 scanner use to be good for years it was free and easy to use. But greedy industry you are better off buying a OBD2 scanner that doesn’t have ads or buy a subscription in order to use this device. I deeply regret buying this garbage.

**Developer response:** Ads and some limitations are only available in the free version of the app. You can use the app without purchasing PRO. If you have any questions or problems, please contact us directly through the app (i) — "Contact Us" — and describe the issue. We'll do our best to assist you.

### 1/5 — Scam

*2026-07-07*

Used to be a great app, then my phone offloaded it and I have to pay$35 to buy it again. No way to restore previous purchase. Never happened before, even though the app offloaded previously. Avoid this, use a different OBD software.

**Developer response:** All App Store licenses are attached to the account you pay from.
Using the same account and re-installing inCarDoc should automatically upgrade the app to Pro.
You might also force an upgrade with
Settings - Buy Pro (scroll to the bottom of the Settings page) - Restore purchase

### 1/5 — doesn't work

*2026-05-20*

I stopped connecting to Elm via WiFi after the latest update.

**Developer response:** If you have any questions or problems, please get in touch with us directly from the app: Home Screen - Information - Contact Us, and be sure to describe your issue in more detail.

### 1/5 — Not much help in pro version

*2025-01-28, version 3.0.2*

No difference between the two for Jeep and Chrysler cars. Just basic stuff.

### 1/5 — Disappointing

*2024-10-04*

This app perpetually disappoints me. There was a recent update and I was so excited that this app may become useful, but no. I regret buying this app.
The most important thing this app needs to do is pull the engine codes. That’s it. Unfortunately, the app does not make it easy to access the engine codes. It would be even better if the app could explain what they mean.

### 1/5 — No longer working

*2024-07-16*

After the latest update, the app has stopped working entirely. This has been incredibly frustrating, as it was functioning well before. Please address this issue as soon as possible.

### 1/5 — Used to be brilliant, the update has broken it!!!

*2024-07-10*

Was great, newest update has broken it!!!

### 1/5 — Used to work

*2024-07-06*

It used to work but now every time I go to the diagnostic trouble codes section the app crashes. It worked before the update for years, but now is completely useless

### 1/5 — Connection problem

*2024-05-31*

Can anyone know instruction for operate on iOS or os system with iPhone got problem to connect

### 5/5 — Must-Have for Car Lovers

*2024-08-09*

As a car enthusiast, I rely on the inCarDoc OBD2 ELM327 Scanner to monitor my vehicle's health. 🛠️ This app is user-friendly, and I love how it provides real-time data on fuel efficiency and engine performance. Definitely a must-have for anyone who loves their car!

### 5/5 — Okay

*2024-07-22*

Works fine, easy cleared my obd2 faults

### 5/5 — The only one I use

*2024-07-22*

I love everything about it!! Great OBD2 app

### 5/5 — Mk7 golf

*2022-12-29*

Changed glow plug on mk7 golf used app to clear eml.. great app

### 5/5 — Fonctionne très bien

*2022-09-10*

Parfait pour les mesures que j’ai à réaliser. 
Dommage que les commentaires négatifs sur cette applis ne soient postés que par des utilisateurs qui souhaitent avoir un menu en FR ou bien autre que EN. 
Ça n’enlève rien à la qualité de cette appli.

### 5/5 — Funktioniert

*2021-08-04*

Konnte Fehler problemlos auslesen und löschen. Danke!

### 5/5 — Very good app does exactly what it says

*2020-12-04*

I got a recommended ELM327 OBDII WiFi adaptor for $20 and downloaded the free version of the InCarDoc app.

Wow it was very easy to use.
Thank you InCarDoc development team.
Great job and thank you for the free version.

I will probably look to buy the Pro version if I find myself wanting more options.

### 5/5 — Recommandé

*2019-10-16*

Une application gratuite qui efface les codes erreur.
 J’ai essayé deux autre application avant celle-ci, mais il fallait payer pour pouvoir effacer un code erreur.

### 5/5 — Connected almost immediately and effortlessly.

*2019-05-21*

Was able to scan and pull up a P0455 code on my wife’s car and let me clear it. I downloaded this app today after my other goto app wouldn’t see any error codes and obviously not let me clear what it couldn’t see.

### 5/5 — Great free app, allows you to clear codes for free!

*2019-01-21*

I don’t understand all of the 1-2 star reviews, mine connected right away.. After trying DashCommand premium ($16) and not having that recognize my 2007 Civic Si, I downloaded a few free apps to try. This was the only one so far that let me clear codes and actually get rid of the check engine light. The car didn’t have to be on, it just needed to be in the position before cranking the engine. EOBD-Facile and Auto Doctor both required subscriptions to clear codes or just wouldn’t connect.
