Automend Pro OBD 2 Car Scanner

When a warning light appears on the dashboard, the hardest part is often not finding a scanner. It is understanding what the scanner is actually telling you and deciding what to do next. I tried Automend Pro OBD 2 Car Scanner with that practical problem in mind: connect a compatible OBDII adapter, read the vehicle’s diagnostic information, and turn an unfamiliar fault into a more informed conversation with a mechanic.

This is a free Auto & Vehicles app from WowSuite Software, aimed at drivers who want more visibility into their car without immediately booking a diagnostic appointment. It has reached over 100K installs, carries a 3.3 average from roughly 350 ratings, and is suitable for Everyone. Those figures suggest a product with a real user base, but also one that has produced mixed experiences. My own impression is similarly balanced: it can be useful as a first checking tool, but it should not be treated as a complete replacement for professional equipment.

From a dashboard warning to a useful first check

The starting condition matters. If the car is running normally and I am simply curious about engine data, a diagnostic app may feel unnecessary. Automend Pro makes more sense when something has changed: a check-engine light comes on, the vehicle begins behaving differently, or I want to verify whether a problem is still present after a repair.

The app’s store summary describes it as an OBDII car scanner and car diagnostic app, while its short description uses the name Automend Pro. In practical terms, that places it in the space between a basic code reader and a workshop diagnostic system. The phone is the display and control point, but the vehicle still needs a compatible OBDII adapter. The app cannot independently inspect a car that has no connection to the vehicle’s diagnostic port.

That distinction is important for first-time users. Installing the app is only one part of the setup. You also need to locate the car’s OBDII socket, plug in the adapter, establish the connection in the way supported by that adapter, and keep the vehicle in the correct ignition state while scanning. If the adapter is poorly made, incompatible, or not receiving power, the app may appear to be the problem even when the real issue sits between the phone and the car.

I would prepare before opening the scan screen. Park safely, avoid testing while driving, and write down what the car was doing before connecting anything. A note such as “light appeared after a cold start” or “engine hesitated during acceleration” makes the eventual code more meaningful. A diagnostic code is a clue; the symptoms and timing help determine whether that clue deserves immediate attention.

What the first connection is really testing

The first connection is not just a technical hurdle. It tests the whole chain: the vehicle’s diagnostic system, the adapter, the phone connection, and the app’s ability to communicate with both sides. I found this a useful way to think about troubleshooting. If the adapter has no power, changing app settings will not help. If the adapter connects to the phone but cannot communicate with the car, the vehicle or adapter becomes the next place to investigate.

That is also why I would not judge the app solely by the first failed attempt. OBDII hardware varies widely, and older vehicles can behave differently from newer ones. Automend Pro is most attractive to someone willing to spend a few minutes checking each link rather than expecting a single tap to solve everything.

Reading the information without jumping to conclusions

Once a connection is established, the useful outcome is not simply seeing a code on a screen. The real value is deciding whether the information changes my next action. For example, a stored code might explain why a warning light appeared, but it does not automatically identify the failed part. Replacing a sensor based only on a code can waste money if the underlying cause is wiring, a leak, a power issue, or another related fault.

This is where a phone-based scanner can be genuinely helpful. I can record the code, compare it with the car’s symptoms, and take that information to a repair shop. The mechanic may still need deeper testing, but the handoff begins with something more precise than “the car feels strange.” That can make the first conversation shorter and more productive.

I would also separate current faults from historical information whenever the app presents them as different states. A code that remains after a repair is not necessarily proof that the repair failed, just as a cleared warning does not prove the underlying issue is permanently solved. The safest workflow is to document what was found, what was repaired, and whether the vehicle’s behavior changes afterward.

A realistic everyday workflow

Imagine a driver whose check-engine light appears on the way home, while the car otherwise feels normal. I would wait until the vehicle is parked, connect the adapter, and use Automend Pro to obtain the available diagnostic information. I would save or write down the result before clearing anything. Then I would search the code using a reliable automotive reference or ask a mechanic what tests should come next.

The important choice is to avoid clearing the warning merely to make the dashboard look normal. Clearing can remove useful evidence and may make it harder for a technician to reproduce the problem. If the light is flashing, the engine is running badly, or the vehicle has lost power, I would stop treating the app as the main solution and prioritize safe professional help.

After a repair, the app can serve as a follow-up checkpoint rather than a certificate of success. I would drive only when the car is safe to operate, observe whether the original symptom returns, and scan again when appropriate. The result I want is not a perfect screen; it is a better-supported decision about whether the vehicle is ready for normal use or needs another inspection.

The handoff between driver, app, and mechanic

Automend Pro works best when I treat it as part of a handoff. The driver supplies the context: symptoms, recent work, fuel or battery events, and when the warning appeared. The app supplies diagnostic information from the vehicle. The mechanic supplies interpretation, physical inspection, testing, and repair. Skipping any one of those roles creates room for mistakes.

A useful handoff note can be simple. I would include the date of the scan, the exact code shown, whether the light was steady or flashing, and what the car was doing at the time. I would also mention whether the code appeared before or after maintenance. This turns a casual scan into a small service record that can save time later.

There is a trade-off here. A professional scan tool may provide broader coverage, manufacturer-specific functions, and more guided testing, while a phone app is easier to keep available and more approachable for occasional checks. Automend Pro therefore competes less with a workshop’s equipment than with the decision to make no check at all. For a driver who wants an early clue, that is a meaningful advantage.

On the other hand, people who already own advanced diagnostic hardware may find the app too limited for their normal workflow. If your work involves programming modules, performing service resets, testing individual components, or diagnosing network communication, a general OBDII app is unlikely to be the right primary tool. I would choose Automend Pro for visibility and preparation, not for specialist repair procedures.

Where the workflow becomes frustrating

The biggest friction point is the dependency on external hardware. The app cannot make an incompatible adapter reliable, and connection problems can be difficult to distinguish from vehicle problems. A user who expects the app to work immediately with only a phone may be disappointed. Before blaming the software, I would confirm that the adapter is powered, seated correctly, and intended for the vehicle and phone connection method being used.

Another limitation is interpretation. A diagnostic code can point toward a system without proving which component has failed. This is especially important for emissions-related warnings, where several different causes can lead to similar symptoms. Automend Pro can help me gather evidence, but it cannot replace a physical inspection or a mechanic’s test plan.

The app’s 3.3 average rating also gives me a reason to keep expectations realistic. It is not a sign that the concept is useless; rather, it reflects how sensitive this type of tool is to vehicle compatibility, adapter quality, and user expectations. A scanner that works smoothly for one car may be less helpful with another, and a user seeking a complete workshop experience may rate a basic diagnostic workflow harshly.

There is also a cost detail worth noticing. The app is free to download, while in-app purchases are listed at $9.99 per item. I would check which part of the experience requires a purchase before depending on it during an urgent repair situation. The free entry point makes experimentation easy, but the total value depends on whether the available functions match the kind of information I actually need.

Who will get the most from it

I think Automend Pro is a good fit for a hands-on owner who wants to understand a warning before visiting a garage, keep basic records of recurring faults, or confirm that a compatible adapter and phone can communicate with a vehicle. It is also useful for someone buying a used car who wants an additional check alongside a proper inspection. In that situation, I would use it as one piece of evidence, never as a guarantee that the car is healthy.

It can also help families or small vehicle owners who share responsibility for maintenance. If one person notices a warning and another takes the car to a mechanic, a recorded scan can reduce confusion. The app becomes more valuable when its output is carried into a real maintenance conversation rather than viewed once and forgotten.

I would skip it as a primary solution if I need guaranteed coverage for a particular manufacturer, advanced module access, guided component testing, or a formal inspection report. I would also avoid relying on it alone when the car is unsafe to drive. In those cases, a professional diagnostic service or a purpose-built tool is the better choice, even if it costs more or requires an appointment.

Compatibility, maintenance, and sensible expectations

The listed minimum operating system is Android 5.0, which makes the app accessible to users with older Android devices. That does not remove the need to consider the adapter and the vehicle, but it does make the phone requirement less demanding than it would be for an app limited to recent devices. I would still keep the phone charged and avoid beginning a scan in a place where losing the connection would create unnecessary stress.

The current version is 1.3.39. I would keep the installation updated when possible, particularly if a connection issue appears after changing phones or adapters. At the same time, an update cannot guarantee that every vehicle or adapter combination will behave identically. The practical test remains the complete workflow: adapter power, phone connection, vehicle communication, readable result, and useful next action.

The Everyone content rating is reassuring for households, but it should not be confused with mechanical simplicity. The app may be easy enough to install, yet the information it exposes still needs careful handling. A teenager can read a code, but an adult should decide whether the car is safe to drive or whether a repair is urgent.

My final assessment after following the whole process

Automend Pro OBD 2 Car Scanner is most convincing when used as a bridge between a dashboard warning and an informed next step. It gives drivers a way to begin investigating with a phone instead of approaching a mechanic with no information at all. The free starting point, broad Android compatibility, and focus on OBDII diagnosis make it approachable for occasional users.

My recommendation comes with a clear boundary: use the scan as evidence, not as a verdict. Save the result, connect it to the vehicle’s symptoms, and pass the information to someone who can test and repair the car properly. Do not erase a warning simply because the screen allows it, and do not continue driving when the vehicle is showing serious symptoms.

In the end, I would recommend it to practical car owners who enjoy doing a first check and understand that diagnostic codes require interpretation. I would not recommend it to someone expecting dealership-level diagnostics from a phone. Its value is in the workflow from input to outcome: connect, observe, document, ask better questions, and decide what deserves professional attention. Used that way, it is a useful companion for basic car diagnosis rather than an unrealistic promise of complete automotive repair.
