If you’re a frequent reader of this website, you probably already know one thing already: I don’t particularly love app powered code readers (or anything wirelessly operated, for that matter).
Now, here’s the thing: I make exceptions every now and then, and when a properly made scanner/code reader comes my way, I don’t hesitate before I add it to my collection. A good example of this is the TopDon TopScan. The same holds true for battery monitors and I especially love the Ancel BM300 Pro.
Generally, however, I’m one to ignore an app-powered code reader/scanner if I can somehow get a wired counterpart of the same model (assuming other things like price remain the same).
There are many good reasons for thinking (and acting) this way as there are challenges of owning an app-powered code reader, especially if it’s your ‘go-to’ unit or a piece you consider the ‘flagship’ of your scanner/code reader collection.
So, what makes the Bluetooth app powered code reader/scanner what you should generally ignore?

The Many Challenges of Owning App Powered Code Readers & Scanners
I’ve already treated the issue of reliability and Bluetooth scanners. If you missed that article, it’s a good time to take a look at it before proceeding with this one.
The above aside, these are the issues you’re likely to face as an owner of app powered code readers and scanners. They are:
1. Reliability Issues
Wireless systems and reliability issues are closely related: you don’t get to talk about one without mentioning the other. The story is the same whether it’s WiFi, Bluetooth, or any sort of connection that doesn’t deal with direct wires.
Granted, a wired connection, all other things being equal, will prove better at connectivity than a system that relies on wireless signals to do its thing.
If you’re interested in wireless dongles and OBD II scanners that rely on a wireless reality to do their thing, this is the first thing to take careful note of.
If you don’t like having to face wireless connectivity issues and don’t appreciate the challenge of dealing with disconnected Bluetooth, then, your best option is to stay within the ‘confines’ of a wired connection.
2. App Support Issues
The challenge of buying and using app powered code readers doesn’t end with the messed-up connections however; support for the apps (which are the heart of the unit) is a potent and valid concern.
With app powered code readers, you’re at the mercy of the app manufacturer to keep the app powering your device updated and up…if for any reason, the company folds up (which happens all the time), you’ll be left with a dongle that effectively, can only now serve as a toy for your toddler.
Sometimes too, the company may not fold up outrightly but for some strange reason, may fail to keep up with the app’s maintenance as they should. In such a case, you’re still at their mercy and can only hope that the unit works as intended when/if they ever decide to fix things.
But, a Wireless Scanner Has Its Advantages Too
This does not mean there aren’t advantages to a wireless scanner or code reader. If you can stomach the challenges of running a Bluetooth connection, then, there’s so much to look up to, on the bright side.
First, dongles are cheap to make and importantly, cheaper to manufacture as against units that require buttons and displays. You’ll be getting OBD II services and functions at a deal you’re likely not to see with the wired units (anywhere).
Secondly, to make up for their obvious challenge, they are usually more feature-packed (for the bucks) than their traditional wired cousins. For some few bucks, you’re guaranteed mid-level functions. Step up a little and you’re into dealer territory. This, certainly, is cool.
Finally, these scanners and code readers are easy to carry or store. I have dongle that periodically gets lost in the glove box of my vehicle! That aside, I love the shock on the faces of the used car salesmen whenever I pull out my fanciful dongle from the pocket and tell them the stories they’re so interested in hiding from me, a few moments later.
In the end, it all bores down to selecting a company that you can bet isn’t going anywhere anytime soon and importantly, one that takes its customers seriously while at it.
What About Battery Monitors?
The logic still holds – and remains valid. While they also work awesomely when they indeed work, what happens when your connection is messed up?
Or, essentially, in the event that the app isn’t supported or the company winds up?
Food for thought.
