Automend Pro OBD 2 Car Scanner

I approached Automend Pro OBD 2 Car Scanner as a practical garage companion rather than a replacement for professional diagnostic equipment. Developed by WowSuite Software, this free Auto & Vehicles app is aimed at drivers who want to connect an OBDII adapter, read information from a car, and make sense of a warning light before deciding what to do next. My overall impression is that it can be useful when treated as a first step, especially if you enjoy checking your own vehicle, but it rewards a careful routine more than casual tapping.

The app has a 3.3 average from around 348 ratings and has passed 100K+ installs, so it has a real user base without looking like a universally polished tool. It is available for Everyone and runs on Android 5.0 or later. The current version is 1.3.39, while the app itself was released on October 25, 2019. Those details matter because compatibility with the phone is only one part of the experience: the car, adapter, ignition state, and supported diagnostic protocols all affect what you actually see.

Starting with a repeatable scan routine

The most reliable way to use Automend Pro is to keep the first connection simple. I would begin with the vehicle parked safely, the OBDII adapter firmly connected, and the ignition switched on in the position that powers the car’s electronics. I would then open the app, select the adapter connection method it supports, and wait for the connection before trying to interpret anything. Rushing through these steps is a common reason a scanner appears unreliable when the real issue is a loose plug, an inactive adapter, or the wrong ignition position.

A useful habit is to scan before clearing anything. If the app shows a diagnostic trouble code, I would record it or take a screenshot, note the date, and write down what the vehicle was doing at the time. A warning light that appeared during a cold start tells a different story from one that appeared after a long drive, even if the displayed code is identical. This small record turns the app from a one-time curiosity into a basic maintenance log.

That distinction is important because a code is usually a clue, not a complete diagnosis. Automend Pro can help reveal that the car’s computer has detected a problem, but the code alone does not prove which component needs replacing. A sensor-related code, for example, can be caused by wiring, a connector, an air leak, or another system affecting the reading. I would use the app to narrow the conversation with a mechanic, not to order parts blindly.

Connection quality also deserves attention. Cheap or poorly made adapters can disconnect, report incomplete information, or behave differently from one vehicle to another. If the app fails to connect, I would first check that the adapter is compatible with the car’s OBDII system, confirm that Bluetooth or another required phone connection is active, and restart the sequence with the ignition on. Testing the same adapter with the same phone in a calm setting is more useful than repeatedly changing several variables at once.

For an everyday example, imagine a check-engine light appearing on the way home. I would park, let the car sit safely, connect the adapter, and run a scan without clearing the warning. If the app returns a code, I would save the result and look for obvious symptoms: rough running, unusual smells, poor starting, or reduced power. If the car feels unsafe or the warning is accompanied by serious mechanical symptoms, I would stop treating the app as the next step and seek professional help. The scanner is most valuable when it improves the next decision, not when it encourages a risky drive.

Settings that deserve a deliberate check

The connection settings are worth checking before assuming the app itself is at fault. Make sure the selected communication option matches the adapter you own, and avoid leaving several nearby vehicle adapters powered at the same time. If more than one device is available, a phone can connect to the wrong one or fail to establish a stable session. I prefer pairing one adapter, closing unrelated vehicle apps, and then launching Automend Pro for a clean test.

It is also sensible to review the app’s display and measurement preferences when they are available on your installation. A value is easier to use when its units match the way you normally think about speed, temperature, or engine information. The point is not cosmetic: inconsistent units can lead to a mistaken comparison with a dashboard reading or a service document. I would set these once, then leave them alone so repeated checks remain comparable.

Do not confuse a setting that changes presentation with one that changes the vehicle. A scanner app may show information from the car, but that does not automatically mean it can safely modify control modules or repair a fault. I would be especially cautious around any action involving clearing trouble codes. Clearing a code can remove an important clue, reset readiness information, or make it harder for a technician to see the original history. My rule is simple: save the result first, understand why the light appeared, and clear only when there is a good reason.

The free price makes it easy to try, but the app also lists in-app purchases at $9.99 per item. I would check what an optional purchase unlocks before paying and decide whether that specific addition solves a problem I actually have. For occasional warning-light checks, paying may not be worthwhile. For someone who regularly maintains several vehicles, an extra capability could make more sense, but the decision should come from a repeated need rather than the assumption that every locked option is essential.

Because this is a phone-based scanner, I would also keep the device charged and avoid handling it while driving. A diagnostic session is best done before moving the car or after parking. If live information is being watched, a passenger can monitor it, but I would still prioritize road safety over a changing number on the screen. The app is more useful as a stationary inspection tool than as a dashboard distraction.

Faster patterns for people who scan often

Experienced use is mostly about reducing avoidable repetition. I would keep the adapter in a known place, use the same phone whenever possible, and follow the same order every time: connect, switch on the ignition, open the app, scan, record, then interpret. A consistent sequence makes failed connections easier to diagnose because you know which step changed.

Another efficient pattern is to separate observation from repair decisions. During the first pass, collect the code and the vehicle symptoms without touching anything. During the second pass, compare the result with the car’s recent behavior and decide whether the next action is a visual inspection, a longer test drive, or professional diagnosis. This prevents the common mistake of seeing an unfamiliar code and immediately buying a replacement part.

I would also scan after a repair only when the vehicle is ready for a meaningful check. If a connector has been reseated or a component replaced, run the app again and compare the result with the earlier record. Do not treat a disappearing warning as proof that the underlying problem is permanently solved. A fault may return only after the car has completed a particular driving pattern, so keeping the original record is more informative than relying on memory.

For owners of older cars, the app can be a useful screening tool before a purchase or long trip, provided the seller or owner permits a scan and the vehicle is tested under honest conditions. A clean screen is not a guarantee of perfect mechanical health, but an active code can justify further questions. I would combine the scan with a cold start, a visual inspection, service records, and an independent inspection when the purchase matters financially.

There is also a practical trade-off between convenience and interpretation. A general OBDII app is easier to carry than a dedicated workshop scanner, and it can give a driver immediate access to engine-related information. However, a workshop tool may communicate with more vehicle modules or provide manufacturer-specific functions that a general phone app cannot replace. Automend Pro makes more sense for basic owner-level checks than for programming, advanced module diagnosis, or a complete professional service workflow.

Where the app’s limits become important

The biggest limitation is that the phone is only the front end of a larger system. The adapter must work, the car must expose compatible information, and the app must interpret what it receives correctly. If one part of that chain fails, the result may be no connection, partial information, or a code that needs more context. I would not judge the app solely by one unsuccessful attempt until the adapter and vehicle setup have been checked separately.

The app should not be used to decide whether a car is safe to drive when there are serious symptoms. A diagnostic code cannot assess brake condition, tire damage, steering problems, overheating risk, or every mechanical fault. Even when the code relates to the engine, the urgency depends on how the vehicle behaves. Flashing warnings, severe shaking, smoke, overheating, or loss of power call for caution and professional advice rather than repeated scans.

Compatibility is another reason to set expectations carefully. The minimum Android requirement is 5.0, but an older supported operating system does not guarantee that every modern adapter or phone behaves identically. I would verify the adapter’s own requirements and test the connection before relying on the app during a trip. This is particularly important if the app is being installed on an older spare phone, where Bluetooth behavior or battery condition may create a separate problem.

The rating also reflects a mixed experience rather than universal satisfaction. Around 3.3 is enough to suggest that some users find value in it while others encounter friction. I read that as a reason to approach the app practically: it can be worth trying because it is free, but I would not build a critical maintenance plan around it without confirming that it works with my exact vehicle and adapter.

Someone who wants a polished maintenance dashboard, broad manufacturer coverage, workshop-grade reporting, or guaranteed interpretation should probably choose a more specialized alternative. A dedicated scanner from a reputable diagnostic brand may cost more, but it can be the better choice for a mechanic, a small fleet, or a driver who needs dependable access to systems beyond basic OBDII information. Automend Pro is a more reasonable fit for learning what the car is reporting and deciding whether further investigation is justified.

Who will get the most from it

I think the app suits a curious owner who already has a compatible adapter and wants a straightforward way to investigate a warning light. It is also useful for people who maintain an older vehicle themselves, compare a car’s behavior before and after a repair, or want a little more information before visiting a garage. The free entry point lowers the risk of trying it, while the optional $9.99 purchases mean regular users can consider extra capabilities only if they genuinely need them.

I would skip it if you expect the app to name the failed part with certainty, perform a complete vehicle health inspection, or replace a mechanic’s diagnostic equipment. I would also skip relying on it if your main concern is a system outside the information normally exposed through basic OBDII communication. In those cases, the usual alternative is a professional scan or a vehicle-specific tool, not a different tapping sequence inside this app.

My best advice is to treat each scan as evidence in a small investigation. Record the original result, connect symptoms to timing, inspect simple causes without guessing, and use a second scan to check whether a repair changed anything. That workflow extracts more value than repeatedly pressing scan or clearing a light because it is annoying. It also protects you from the most expensive mistake: confusing a code with a confirmed repair.

My verdict after using it as an owner’s tool

Automend Pro OBD 2 Car Scanner is a useful, modestly positioned Android app for basic car diagnostics. WowSuite Software has made something approachable for drivers who want to read OBDII information without immediately buying workshop equipment. Its strongest quality is the possibility of a quick first check, especially when the user brings a compatible adapter and a disciplined recording habit.

At the same time, the mixed 3.3 average, adapter dependence, optional purchases, and limits of general OBDII data keep me from recommending it as a complete diagnostic solution. I would recommend trying it for owner-level investigation, not trusting it as the final authority. If it connects reliably to your vehicle, it can save a needless trip for a simple question and give a mechanic better starting information. If it does not connect or the problem is clearly serious, move on quickly rather than forcing the app to do a job it was never meant to handle.

The right mindset is to use Automend Pro as a first diagnostic conversation with your car, not as a magic repair button. With a repeatable baseline workflow, sensible settings, saved scan results, and honest awareness of its limits, the app earns a place in an owner’s toolkit. Without those habits, it is easy to mistake a convenient screen for a complete diagnosis, and that is where its practical value ends.
