Perhaps the whole line is being discontinued, since on HD's website, they no longer show a in store pick up option. In the stores I visited, the thermometer was marked down to $20 (normally $40) and the inspection scope was lowered from $100 to $70. These tools are in the clearance section at the end of aisles in some stores, while in other store they are still in the tools sections, but with the prices lowered.
I bought the thermometer since it was only $20, and was the only Phone Works tool that had decent reviews. Some of the main issues with the reviews is that the app didn't work for newer phones and that you had to jump through a lot of hoops, including signing up for Ryobi account and scanning the QR code on the device itself, just to be able to use it.
However, other than taking me like 10 minutes to rip open the plastic cover, I just downloaded the app to my iPhone 6, plugged the thermometer in, and it worked out of the box, without needing me to sign up for any account or scan the QR code or anything.
I tested it out a bit and it worked well, since the device itself has a laser pointer, and it also uses the camera on the phone, so you can take a picture of whatever you are measuring the temperature of as a record.
If anyone is interested in this device, maybe check your local Home Depot to see if they've got it on clearance as well.
