AlfaOBD is an Android diagnostic application from AlfaOBD Autodiag. It targets vehicles from Stellantis, the group formerly known as FCA: Alfa-Romeo, Fiat, Lancia, Dodge, RAM, Chrysler and Jeep, with Peugeot Boxer and Citroen Jumper vans also covered. The app sells for $49, carries no advertising and offers no in-app purchases, so the price you see is the whole cost of the software.
The reason to consider it over a generic OBDII reader is native support for the electronic control units used in these cars. Generic tools tend to expose a limited set of emissions-related parameters; this one is built around the modules the manufacturer actually fitted, which is what makes dealer-level procedures possible at all. The developer describes the app as aimed primarily at car owners while providing the capabilities of professional scanners, and that combination is the pitch: workshop-grade access without a workshop-grade price tag.
What native ECU support changes
The distinction between native support and generic OBDII is not marketing decoration. A generic app reads what every car must expose by law, which on a Fiat-group vehicle is a thin slice of what the car knows. AlfaOBD instead speaks to the control units directly, so the data and procedures on offer come from the modules themselves rather than from a standardized subset.
That reach shows up in several places. The app monitors dynamic parameters from the engine, gearbox, ABS and climate control units and draws them as plots, so you can watch values move rather than reading a single frozen number. It also reads static information: control unit identification, system status, fault codes with probable causes where the software can supply them, and environment information recorded around a fault. Fault codes can be cleared from within the app.
Beyond reading, there are active diagnostics and configuration procedures for equipment governed by the engine, gearbox, body computer, climate control, ABS, airbag and code control units, among others. Electronic key and RF remote programming is included as well, which is the sort of job that would otherwise mean a trip to a dealer. The developer maintains a full list of supported control units on its website, and checking that list against your own car before buying is the sensible first step.
The 2018 security gateway hurdle
One requirement deserves attention before anything else, because it decides whether the app can do its job on your car. FCA vehicles from model year 2018 onward carry a security gateway module that blocks third-party diagnostics. To reach the full set of features on those cars, an SGW bypass is needed; without one, the gateway stands between the app and the modules it wants to talk to.
There is a further wrinkle for owners of the Fiat 500X, Jeep Renegade and Jeep Compass built on the MP platform. A bypass that ignores that bus will not give those models the access their layout requires.
This is not a small footnote. Anyone shopping for a bypass should treat the model-specific advice as part of the purchase decision, not an afterthought, because the wrong unit produces exactly the kind of connection trouble the app's own error messages describe.
What the app needs from you
AlfaOBD does not communicate with a car on its own. You need a compatible OBD interface, and the developer publishes the list of supported ones on the AlfaOBD website. Checking the list before buying an interface is the first thing to confirm.
The app also gives a diagnostic clue for interface trouble. If it cannot reach a control unit and reports "Interface reports NO DATA" or "Interface reports CAN ERROR", the likely explanation is that the interface is incompatible or faulty rather than a problem with the car. That message is worth remembering, since it saves time spent suspecting the vehicle.
Setup details for both the interface connection and the car connection are covered in a help document the developer hosts online. Between the supported-interface list, the help file and the control unit list, most of the preparation happens away from the phone, before the first connection is attempted.
There is one platform note as well. If Google Play does not list your Android device, so you cannot install or update, the developer asks you to email [email protected]. The current release is a quick fix for Android 15, so the app is being kept current with recent Android versions.
Working through live data and faults
A sensible way to use the app is to start with identification and fault reading, then move to live data, and only then consider configuration work. Reading control unit identification and stored fault codes is low-risk and tells you what you are dealing with. Fault codes arrive with probable causes and, where applicable, the environmental conditions recorded when the fault occurred, which together give a much better starting point than a bare code number.
Live plotting is where the app earns its keep for diagnosis. Watching engine, gearbox, ABS or climate control parameters as traces lets you compare behavior under different conditions rather than guessing from a snapshot. If the plots refuse to update, the developer notes that "Force GPU rendering" should be switched off in the device's developer options; that setting is the first thing to check before assuming something is broken.
Configuration and active procedures are the deepest end of the tool, and they are also where care matters most. Changing settings on a body computer or running an active test is a deliberate act, not a casual tap. Reading the help documentation before touching those functions is the difference between using a professional-grade tool well and creating a problem you then have to diagnose.
Language is one less obstacle: the interface is available in Czech, English, French, German, Hungarian, Italian, Polish, Portuguese, Russian, Turkish and Spanish, chosen from the settings menu.
Where the money and the ratings land
At $49 with no ads and no in-app purchases, AlfaOBD is priced as a tool rather than a toy. That figure buys the software alone; the OBD interface and, on newer cars, an SGW bypass are separate purchases you will need to make for the app to be useful. Adding those up is the honest way to judge whether the total makes sense against what a dealer would charge for the same jobs.
The app has been installed more than 100,000 times and holds a 3.3 average from 2,234 ratings. That is a middling score for a paid diagnostic tool, and a plausible reading of it is that software depending on a compatible interface and, on many cars, a bypass will collect poor marks from people whose hardware or vehicle does not match.
None of that changes what the app is. It is a specialist tool for a defined set of vehicles, sold outright, with no advertising to work around and no purchases to weigh. The price and the rating are simply part of the picture you should have before deciding.
A tool for owners of the right cars
AlfaOBD makes sense if you own an Alfa-Romeo, Fiat, Lancia, Dodge, RAM, Chrysler or Jeep, or one of the two supported van models, and you want access to the control units rather than a generic read of the emissions systems. It suits the owner who is willing to buy a compatible interface, check the supported control unit list, and read the help documentation before connecting. The reward is dealer-level diagnostics, live plotting and configuration procedures in one paid app.
It suits less well anyone who wants a plug-in-and-go code reader with no hardware decisions to make. The interface requirement is real, the security gateway on 2018-and-later cars is real, and the model-specific bypass advice for the 500X, Renegade and Compass adds another check before you start. If your car is older, or already has the right bypass fitted, the path is much simpler.
For the right vehicle and the right owner, the appeal is straightforward: native support for the modules these cars actually use, fault codes with context, live data as plots, and configuration and key programming that would otherwise mean a dealer visit. At $49 with no ads or purchases attached, it is a considered purchase rather than an impulse one, and it rewards the buyer who does the preparation first.
The short verdict
A $49 specialist diagnostic app for Stellantis vehicles that rewards owners who check their interface and security gateway needs first.

AlfaOBD: frequently asked questions
Which cars does AlfaOBD cover?
The app is built for vehicles from Stellantis, the group formerly called FCA. That includes Alfa-Romeo, Fiat, Lancia, Dodge, RAM, Chrysler and Jeep, and the Peugeot Boxer and Citroen Jumper vans are supported as well. The developer publishes a full list of supported control units on the AlfaOBD website, which is the place to confirm your specific model.
Do I need anything besides the app to use it?
Yes. AlfaOBD needs a compatible OBD interface to talk to the car, and the developer maintains a list of supported interfaces on its website. If the app cannot reach a control unit and reports "Interface reports NO DATA" or "Interface reports CAN ERROR", the interface is most likely incompatible or faulty. Setup details for connecting the interface and the car are covered in the online help document.
Why do newer FCA cars need extra hardware?
FCA vehicles from model year 2018 onward have a security gateway module installed, and it blocks third-party diagnostics. To reach the full set of diagnostic features on those cars, an SGW bypass is required. On the MP platform (Fiat 500X, Jeep Renegade, Jeep Compass), the bypass must also cover the second high-speed CAN bus at pins 12 and 13.
What does the app cost, and are there ads or purchases?
AlfaOBD is a paid app priced at $49. It contains no advertising and offers no in-app purchases, so the purchase price is the full cost of the software itself. The OBD interface, and any security gateway bypass your car needs, are separate items you would buy elsewhere.
What can it actually read and do?
It reads control unit identification, system status and fault codes, including probable causes and environment information where available, and it can clear fault codes. It reads live values from the engine, gearbox, ABS and climate units and charts them. It also provides active diagnostics and configuration procedures for various equipment, plus electronic key and RF remote control programming.
