Love it, east simple, No ads, No 1000folded mandatory cookies acceptance just and app as it all should be 💪🏼💪🏼 ace for developers🙏🏼💪🏼

★★★★★ Jay Andersen · Jan 6, 2025

I have an older Samsung Android phone. I downloaded this app, plugged the Klein Horoscope into my phone's USB-C, said 'Yes' to all permissions pop-ups. The app opened and the boro camera image came right up. It's easy to adjust brightness and other settings.

★★★★☆ Daxx Axx · Jun 20, 2024

Not bad, ran into a little problem when I had the scope plugged in first and the app not picking it up. All I did was unplug it, then plug it back into the phone with the app already open. Connected right up and was good to go! There may be a manual that originally came with it that probably tells you that, we bought it at a garage sale for like $20. But it's not needed, just download the app and plug it in, and your good to go. Minimal knowledge or experience to use.

★★★★★ Max Geisler · Oct 16, 2025

So far so good! Installed it on my Galaxy s24 about 10 minutes ago - - instantly produced clear pictures and works just fine. About time somebody came up with a tool and application like this one! Bought the borescope/mechanical unit from a big box hardware store for under $40 -- great improvement compared to freestanding units that cost hundreds more. (I'd expect no less from Klein Tools, one of America's oldest and best manufacturers.)

★★☆☆☆ Meredith K Carlson · Jul 19, 2024

This was so ridiculous. Could not get the E16 endoscope to work with the Klein app. Download another app called USB Endoscope Camera for Samsung, and you should be good to go.

★☆☆☆☆ Joseph Tarlue · Feb 4, 2025

This application does not work at all.... I'm going to use this product one time. Once you plug in the USB-C there's no video, it only takes me to the apps' menu, but there's no display of anything. I WISH I COULD GIVE A ZERO

★☆☆☆☆ David Arnold · Apr 1, 2025

Does not work on my phones (with an s). Installed, removed, re-installed... Tried the different combinations of the camera plugged in vs not with both installations and app opening. Nada. But it will definitely suck down battery with the light. Unfortunately, it does not recognize the camera at all, so I could not actually use the camera or the app. I'm pretty disappointed.

★☆☆☆☆ Alexander H · Aug 31, 2024

Doesn't work. Returning this borescope. Klein needs to fix their app. Don't buy.

Trust & Safety: This app requests CAMERA and STORAGE permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, READ_MEDIA_AUDIO/IMAGES/VIDEO) as well as network access (INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE) to operate the borescope feed and updates. A notable UX note in recent changes indicates that camera permission prompts can lock users out if declined, requiring permission changes via device settings to continue.
