Automend Pro OBD 2 Car Scanner

Analysis by Getfullapps

I approached Automend Pro OBD 2 Car Scanner as a practical garage companion rather than a replacement for a professional diagnostic tool. It is a free Android app in the Auto & Vehicles category from WowSuite Software, built around the idea of reading information from a car through an OBDII adapter. That sounds simple, but the usefulness depends heavily on the vehicle, the adapter, and how carefully you interpret what appears on screen.

My overall impression is mixed but worthwhile. The app can help a driver understand a warning light, check whether a problem is still present, or keep an eye on vehicle information without immediately visiting a workshop. At the same time, it is not the sort of application I would trust as the only basis for an expensive repair. Its average rating of 3.3 from 348 ratings reflects that middle ground: there is a useful idea here, but the experience is not equally smooth for every phone, car, or adapter.

How I would use Automend Pro in a normal diagnostic routine

I’d keep a normal scan deliberately simple: connect while parked, check that the car responds, record any codes before changing anything, and note what the vehicle was doing at the time. That routine makes repeat visits more useful because I can compare like with like rather than relying on memory. From there, the next question is whether a failed connection points to the app—or to something outside it.

Start with the connection, not the app

The first practical lesson is that the app cannot compensate for a poor OBDII connection. Before opening the scanner, I would make sure the adapter is firmly seated in the vehicle’s diagnostic port and that the car is in the correct ignition state. Some vehicles expose the port in an awkward position, so a loose connection can look like an application failure when the real issue is physical.

I would also avoid beginning with a moving vehicle. A parked car gives me time to pair the phone, select the adapter connection method where applicable, and watch for a stable response. This is especially important when the goal is to investigate a warning light. Rushing through setup while sitting at the roadside can lead to a false conclusion that the app cannot communicate with the car.

Once connected, I would treat the first session as a baseline. I would note whether the app connects quickly, whether the vehicle responds consistently, and whether the information shown makes sense for that car. The same scanner can feel reliable in one vehicle and limited in another because OBDII support varies by model, engine system, and manufacturer.

Read a fault before deciding what it means

A diagnostic code is a clue, not a complete repair instruction. If Automend Pro displays a code, I would write it down before clearing anything. I would also record what the car was doing at the time: rough running, poor starting, unusual fuel use, a change in performance, or simply an illuminated warning lamp with no obvious symptoms.

This habit matters because clearing a code can remove useful evidence without fixing the underlying cause. My preferred workflow is to read first, take a screenshot or written note, inspect the code description, and only then decide whether clearing it is appropriate. If the warning returns, that recurrence is more informative than a clean screen immediately after deletion.

For a minor issue, such as a warning that appeared after a weak battery or a temporary sensor irregularity, the app may help me decide whether to monitor the car. For a flashing warning light, severe loss of power, overheating, smoke, or unsafe handling, I would stop treating the phone as the main diagnostic authority and seek qualified help instead.

Use it as a conversation aid at a workshop

One of the most useful everyday roles for this app is preparing for a mechanic visit. If I can capture the code, the date of the reading, and the symptoms, I can describe the problem more clearly. That does not prove which component needs replacement, but it gives the conversation a better starting point.

I would be careful not to present a code as a confirmed diagnosis. A single fault can be triggered by wiring, a connector, a sensor, a vacuum issue, or a broader system problem. The app is most valuable here as a translation and record-keeping aid, not as permission to order parts immediately.

A realistic roadside example

Imagine that I start the car before work and the engine warning lamp appears, but the vehicle still drives normally. I could park safely, connect the adapter, and use the app to read the stored code. I would save the result, check whether the light is steady or flashing, and compare the code with the car’s behavior. If the issue looks non-urgent, I might drive carefully to a workshop with the information ready. If the engine is shaking badly or the warning is flashing, I would not use a reassuring-looking app screen to justify continuing.

This is where the application earns its place: it can reduce uncertainty during the first few minutes. It cannot remove the need for judgment, proper testing, or a repair manual.

What I would check in the settings

Experienced use begins with checking the connection and display choices before relying on live information. I would look for the available adapter or communication option, confirm that the selected method matches the hardware I own, and make sure the phone is not switching away from the connection during a session. A scanner app is only as dependable as the link between the phone, adapter, and vehicle.

I would also pay attention to units and presentation. If the app allows a choice between measurement systems, I would select the one I already use for maintenance records. Mixing units across different readings makes it easier to misread temperature, speed, or other values. Even when a number looks familiar, I would ask whether it describes the current value, a calculated estimate, or a value supplied by the vehicle’s control system.

Another setting worth checking is the way information is refreshed. Live data can be useful while observing a symptom, but rapidly changing values are not automatically more accurate or more meaningful. I prefer a stable view that lets me compare readings under the same conditions: engine off, ignition on, idle, and a controlled drive if the information is safe to observe. The important habit is consistency rather than chasing every changing number.

Protect the quality of your observations

I would avoid making comparisons between sessions unless the conditions are similar. A cold engine and a fully warmed engine naturally produce different readings. Electrical accessories, outside temperature, recent driving, and battery condition can also influence what the car reports. Recording the situation beside the code or reading makes the app much more useful later.

For example, if I am watching a suspected temperature-related problem, I would note whether the engine had just been started or had already been driven. If I am investigating an intermittent fault, I would record whether it appeared during starting, acceleration, cruising, or idling. The app provides the window into the vehicle, but the quality of the conclusion depends on the notes around that window.

Use repeatable shortcuts instead of random scanning

The fastest users are not necessarily the ones who open every screen. They are the ones who repeat the same small process each time. My shortcut would be: connect, confirm the vehicle response, read stored faults, record them, observe the relevant symptoms, and only then consider clearing or testing again. Repeating this order prevents a familiar mistake—jumping straight to deletion because the warning is annoying.

I would keep a simple record on the phone of the code, mileage if I track it separately, symptoms, and what happened afterward. This is particularly helpful for faults that disappear and return weeks later. A single scan can be vague; a pattern across several scans can show whether the issue is becoming more frequent or only appears under a specific condition.

Another efficient pattern is to use the app before buying anything. If a warning suggests a sensor-related problem, I would use the result to research the diagnostic process, inspect accessible connectors, or ask a mechanic focused questions. I would not use it to select a replacement part solely from one code. That restraint can save money because the first code in the chain is not always the failed component.

When clearing codes is useful—and when it is not

Clearing a code can make sense after a repair or after documenting a temporary event, but I would never treat it as a repair. The better test is what happens afterward. If the code stays away and the symptoms are gone, the original event may have been temporary, although that still does not prove the car is perfect. If it returns quickly, the recurrence is evidence that further diagnosis is needed.

I would be especially cautious before clearing codes on a vehicle that is about to be inspected, sold, or taken to a workshop. A freshly cleared system may not immediately show all readiness information, and the absence of a warning right after clearing is not the same as a clean bill of health. Keeping the original record protects both the owner and the person trying to diagnose the car.

Where the app’s reach ends

The biggest limitation is inherent in phone-based OBD scanning: access is shaped by the vehicle and the adapter. Generic OBDII functions can be useful, but manufacturer-specific systems may require equipment and software designed for that particular brand. A basic scanner app should not be expected to replace dealer-level access, advanced module testing, programming, or guided component diagnosis.

This distinction matters when a car has an airbag, braking, transmission, or body-control problem. An app focused on OBDII engine diagnostics may not provide the depth needed for those systems. If the issue concerns a safety-critical feature, I would choose a qualified technician or a tool explicitly designed to communicate with the relevant module.

Compatibility is another practical trade-off. Automend Pro requires Android 5.0 or later, and the current version is 1.3.39. Those details make it accessible to many older Android phones, but they do not guarantee that every vehicle or adapter will behave identically. Before relying on it for travel, I would test the complete setup at home rather than discovering a connection problem beside a disabled car.

Free access with an important cost detail

The app is free to install, which makes it easy to try without committing money at the beginning. There are in-app purchases priced at $9.99 per item, so I would check what an optional purchase unlocks before paying and decide whether those functions match my actual needs. For occasional code reading, a free starting point may be enough; for frequent monitoring, the value depends on how consistently the app works with the vehicle and adapter.

I would not choose it simply because it costs less than a workshop visit. A cheap scan that leads to the wrong part can become expensive. The sensible calculation is whether the app helps me ask better questions, notice a recurring issue, or avoid an unnecessary trip—not whether it can replace every professional test.

Who will get the most from it

I think Automend Pro is best suited to drivers who already own a compatible OBDII adapter and want a convenient first look at engine-related information. It also suits careful DIY owners who understand that codes need context. Someone maintaining an older daily driver may appreciate having a scanner available before a long journey, especially when a warning appears but the car still seems normal.

It is less suitable for a person who expects a single tap to identify the exact failed part. It is also not my recommendation for someone unwilling to read code descriptions critically, keep notes, or verify a result. Drivers dealing with recurring safety-system warnings, complex electrical faults, or manufacturer-specific problems will usually be better served by a workshop or a more specialized diagnostic platform.

My final view after adopting a repeatable habit

Automend Pro OBD 2 Car Scanner has a clear practical role: it gives an Android phone a way to participate in basic vehicle diagnosis when the right adapter and a supported vehicle are available. Its strongest feature is not a promise of certainty; it is the ability to make the first investigation more informed. I can read a warning, preserve the evidence, compare symptoms, and arrive at a repair conversation better prepared.

The app’s 100K+ installs show that it has reached a substantial group of drivers, while its Everyone content rating makes the intended audience broad. Still, broad accessibility should not be confused with professional depth. I would use it as a first-pass tool, a monitoring aid, and a record of recurring problems—not as a substitute for electrical testing, manufacturer-specific equipment, or mechanical experience.

My recommendation is therefore conditional but positive. If you have a compatible adapter, want basic OBDII information, and are comfortable treating results as clues, it is worth trying. If you need guaranteed coverage of every vehicle system or a definitive repair answer, choose a specialist alternative instead. The best results come from combining the app with disciplined notes, repeatable connection habits, and sensible limits on what a code can prove.
