OPPLE Smart 4+

Very confusing to get the device set up. It seems that you need to create an account, then click the remote button, then give it access. The QR code to scan just leads you into a loop of downloading the app or crashing if you scan it in the app as it instructs. The guest button doesn't allow you to use the Light Meter and might be for some other product completely.

The Registration page and login are a little confusing. Currently, there is an email verification button on the signup page. But it isn’t immediately obvious that you need to create a password first. The page layout is slightly confusing. Then login doesn’t seem to work using a password. I needed to use the “email login” link instead. But once that was finished, the rest of setup was good. As for quality, this is pretty decent. It’s not comparable to a $2,000 spectrometer, but this is an excellent quality device and app for the price!

First of all, the Light Master IV wouldn’t show up as a Bluetooth on any iOS phone. It only shows up on Android. So I was never able to fully test the function of this app.

However, it was clear even from the initial setup and login screens on that app that this app is poorly thought out, clunky, and generally not a good UX.

Terrible translation of menus and phrases into English, to the point that it’s unintelligible at times. Typos and grammatical errors.

The app initially asks you to open your camera to scan the QR code on the device. But that just opens the App Store to download the app. But I had ALREADY downloaded the app, so it’s just a weird circular logic.

The text colors aren’t even well chosen—it looks like text is greyed out because that function is disabled, but in fact, you can still click it.

Overall a confusing, poorly thought out app. Not that it matters, because the iPhone doesn’t recognize the device anyway, so I’m returning the device for a refund and writing this poor review.
