Would love an option for CarPlay to display live data, etc. ### 4/5 — 2026 Ram 1500 RHO *2026-06-13, version 15.43* I have used this app for for previous Jeep and it was great. I now have a RHO but there is no support? Any idea on an update? ### 3/5 — Language *2026-06-12* I don't understand why you still haven't put French ### 4/5 — Great App, More Diagnosis Help *2026-01-16, version 15.34* The app works seamless with my Jeep JK. But once I get a trouble code, it would be nice for there to be more information on a diagnosis of what it might be, maybe more symptoms you’re having if it is. That sort of thing but overall great app ### 3/5 — Decent *2026-01-08, version 15.34* Use to work really well to force regen on my eco diesel but now it always crashes or wont connect ### 4/5 — Gladiator *2025-12-23, version 15.34* Pretty easy to use but I wish the TPMS pressure went by 1s as 30 is too low for mine and 35 is too high. I would like a 32 or 33 option. ### 5/5 — lingua *2025-12-19, version 15.34* Sarebbe bello mettere la lingua Italiana ### 4/5 — Klasse App mit 1 Stern Abzug *2025-12-12* Ich nutze diese App gerne, da ich einen Chrysler 300 C 3,5 l AWD Fahre. An sich unterstützt die App vieles und es macht Spaß sie zu benutzen da viel möglich ist. Ein Stern Abzug gibt es, weil ich das Getriebe 5 Gang 722.6 nicht nach Routinen anlernen kann auch eine Abschaltung der Wandler Überbrückungskupplung oder ähnliche Sachen, da hier so gut wie alle Optionen Fehler werfen und error Conditions not correct, oder error Not supportet die mit dem Getriebe zu tun haben, wären hier super ich würde mich freuen, wenn hier spezifisch auf die Getriebes Sache noch mal eingegangen werden Könnte dann gibt es volle Punktzahl. ### 2/5 — It will not load *2025-12-09, version 15.32* When I first got it it was a little bit of a pain to get it to work. But now I can’t get it to do anything but demo mode ### 4/5 — Ajout de langue *2025-11-16* Superbe application complète mais serait il possible d ajouter le langage français vous auriez plus d acheteur car la non compréhension de l anglais pénalise fortement l utilisation ### 5/5 — Amazing *2025-11-12, version 15.31* Best app there is if you own a Jeep. This thing has been a godsend. Highly recommend. ### 5/5 — Works Great and Easy *2025-10-25, version 15.30* I got the app to check codes and configurations on my 22 Ram 2500 and it has been beyond phenomenal. With one button click, I can scan every module and sensor for dtc’s and clear any that show up. I have been able to program key fobs, modify TPMS settings, change tire size for speedometer correction, activate remote start and more. All of this by someone who is very tech illiterate. Have not had to contact customer support for any reason. Have been completely satisfied with its capabilities and ease of use. ### 5/5 — Au top mais ☺️ *2025-09-29* Serait-il possible d’avoir une version en français et la elle serait au top du top 😅 ## Most critical reviews (10 lowest-rated) ### 1/5 — no jeep renegade *2026-08-16, version 15.44* no jeep renegade ### 1/5 — Horrible customer service *2026-03-30, version 15.39* I purchased this app & the bypass cable and Bluetooth scanner. Everything was working fine at first. I noticed my DRL where not on during the day so I went to try and reset it with the app and began receiving error messages. Contact JScan through FB messenger and the customer service agent was very short and snarky in there response. Told me I had a non compatible scanner. I purchased a compatible scanner from there list and am receiving the same messages. Reached out through messenger again and no response. What a waste of time and money. ### 1/5 — SCR features and support lacking *2026-03-20, version 15.37* Attempted to purchase VIN license within the app. Transaction still says pending over 14 hours later. Only way to contact support is Facebook. Reached out approximately 11am est. they replied back approx. 3AM. Their answer was payment processing isn’t their problem. I was able to find a work around using my Apple ID from a Mac I purchased the license and it then appeared on the phone to apply to the VIN. After applying I ran diagnostics. The error code matched what I was able to get from the RAM dash. Codes wouldn’t clear despite adding the new sensors, wouldn’t relearn after NOx install, SCR count down wouldn’t reset. I used a OBDLINK MX+ blutooth connection. Advice; Test the free version if you like for basic code clearing, license likely isn’t worth it for RAM. Don’t expect valuable support. ### 1/5 — Options *2025-11-28, version 15.32* I wish there was a way to set the threshold of the front and rear tpms separately. I use my jeep for search and rescue. And in other emergency situations. Being able to have less air in the rear helps when 4 wheel drive can’t be used due to sharp turns but need more traction ### 1/5 — Scrambled 2025 Jeep JL and had to restore to stock *2025-10-16, version 15.30* The new 2025’s with the updated dash and radio make this tool NOT COMPATIBLE. Just in trying to change tire size, it screwed up many of the driver convenience items as well as the cruise control, headlight controls, handling features and more. They know they have a problem but did not update their Compatible Vehicles list. I’m just lucky that the restore to original configuration worked! ### 1/5 — Русский язык добавить надо! *2025-09-27* Хорошая прога! Но для удобства в пользовании желательно добавить Русский язык!!! ### 1/5 — Won’t conect to my WiFi. *2025-09-25, version 15.29* I plugged the OBD reader and show the WiFi signal,but won’t connect”connection error “ ### 1/5 — Doesn’t work *2025-09-08, version 15.28* Doesn’t work on 2024 Charger Daytona and I don’t do Facebook ### 1/5 — Poor Support *2025-08-27, version 15.28* Can’t add my new vehicle, got poor support, do not recommend. ### 1/5 — Dpf regen did not work *2025-07-04, version 15.27* I tried to get the dpf regen to work and kept getting an error message. This was the reason I purchased this app and it wouldn’t do what I needed it to do. I will buy a cheap android tablet and use Alfa obd ## Most praised reviews (10 highest-rated) ### 5/5 — Super application pour jeep wrangler *2026-07-10* Encore merci pour cette superbe application très efficace et indispensable pour tout les possesseurs de jeep mais si pouvez la traduire en français et compatible avec car play pour l’avoir directement sur autoradio ça serait encore plus génial merci par avance **Developer response:** Send us message on OBD JScan Facebook page and we will try to helpy you with that problem. ### 5/5 — Bueno *2026-06-10, version 15.42* Excelente ### 5/5 — Great price great program *2026-06-06, version 15.42* Successfully flashed ABS module vin. Also successfully completed ABS initialization. ### 5/5 — Very cool *2026-05-11, version 15.41* I really like this app. Used it on a JK and now on my JL 4xe. Wish it was CarPlay compatible… : ) ### 5/5 — Great App for KL Cherokee *2026-05-11, version 15.41* Got this app to use with my Vgate MC+ on my 2016 Cherokee. Works great! I changed my infotainment system and was able to do a proxy alignment without having to take it to the dealership. I did unfortunately try to disable the stupid stop start. But it also disables the remote start. When I changed it back, something happened and now there’s a p1500 permanent code for the VSS. It’s supposed to go away over time after relearn. No check engine light associated with it though. Hasn’t affected anything. Would like to see a backup option. If there is one, I couldn’t find it. ### 5/5 — Very handy app *2026-05-06, version 15.41* Very useful for diagnosing issues with your Jeep,dodge,Ram. Will save you $$$ to find errors rather than pay a mechanic to To the same task, there are plenty of sites online to define each error code and what it relates to as well as how to fix it. ### 5/5 — Da avere *2026-05-04, version 15.41* Se hai una RAM, è semplicemente un’app che non può mancare. A un costo davvero irrisorio offre un livello di controllo e personalizzazione che normalmente ti aspetteresti da strumenti ben più costosi. Permette di configurare una quantità enorme di opzioni del veicolo in modo semplice e intuitivo, rendendo accessibili anche funzioni che spesso restano “nascoste”. Oltre alla parte di configurazione, è eccellente anche per il monitoraggio: lettura e gestione degli errori chiara, veloce e affidabile. Perfetta sia per chi vuole smanettare un po’ di più sulla propria RAM, sia per chi vuole semplicemente tenere sotto controllo lo stato dell’auto senza complicazioni. In poche parole: costa poco, fa tantissimo, ed è uno di quegli strumenti che una volta provati non puoi più farne a meno. ### 5/5 — JScan *2026-03-02, version 15.37* I bought a license for my Ram, I got the iCar pro BLE 4.0 to use the app and let me say so far it’s wicked. I put bigger tires on my truck re-calibrated my Speedo and it’s bang on now. Super easy to use as well, so many things one could go through on their vehicle. A must have A+++ guys. ### 5/5 — Reliable and convenient *2026-02-10* Really working app. Added a key, activated remote start on my WK2 CRD 2013 facelift. Everything is clear, pop-up hints are also useful. Got in touch with Support before purchasing a licence — received prompt answers. V-Gate OBD Bluetooth worked well. ### 5/5 — Must have for Jeep Chrysler *2026-01-16, version 15.34* I originally purchased to chase an engine issue. Replaced crankshaft sensor and did a reset. Lately I needed extra keys for 2014 jeep jk. Ordered third party fob/key blanks and had them cut and was able to program keys myself. That alone more than paid for the app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
