Godsend app alerts you of smart glasses that might be secretly recording you


A new Android app can warn you if someone wearing glasses like the Meta Ray-Bans is close by. 404 Media first spotted the tool, called Nearby Glasses. It works by picking up Bluetooth signals these devices constantly send out, then firing a notification when it finds one.

Yves Jeanrenaud, a hobbyist developer and sociologist, built it as what he calls “a tiny part of resistance against surveillance tech.” You can download it now from the Play Store or GitHub if you are uneasy about being recorded without knowing it in public.

How the smart glasses detector works

Nearby Glasses hunts for Bluetooth advertising frames, the small data packets devices broadcast as part of their routine operation. When it spots a frame from certain manufacturers, it alerts you. Jeanrenaud explained that the app simply checks for those frames and sends a notification when it finds a match.

To use it, grab the app from the Play Store or GitHub. You might need to adjust settings like enabling foreground service to keep it scanning in the background. Tap “Start Scanning” and a debug log shows you what it detects. If it thinks smart glasses are near, you get a message that reads “Smart Glasses are probably nearby.”

The false positive problem and its limits

The app is not flawless, and Jeanrenaud is honest about that. Its Play Store page warns of likely false alarms, especially from VR headsets. In one test, it spotted a Meta Quest 2 and sent a smart glasses alert, with the debug log correctly naming the device.

The developer keeps expectations grounded. He said this is a tech fix for a social issue blown up by tech, and he does not want people to feel falsely secure. It remains imperfect. Still, you are far less likely to run into someone wearing a VR headset than a pair of smart glasses while out.

What comes next for fighting smart glasses surveillance

This tool arrives as glasses grow more powerful. Meta is reportedly developing a facial recognition feature called Name Tag that would let wearers identify people and get information through its AI assistant. That possibility makes a detector like this more timely.

For now, Nearby Glasses gives you a way to push back, even with its flaws. You can find it on the Play Store or GitHub and start using it today. Just remember the creator’s advice: treat it as one small tool, not a complete shield. The goal is staying aware, not feeling invincible.

Have you ever wanted to pick up a new Ryobi tool, but saw the price and slowly (or quickly) backed away? There’s a much better place than Home Depot to buy your Ryobi tools, where you’ll pay lower prices and still get a warranty.

It’s great to have a source like Home Depot if you need that one specific tool

There have been many times when I have been in a pinch and needed a tool right then and there, and I was very happy to have Home Depot not far away. Home Depot sells some of my favorite brands, and almost always has the tools I need in stock.

The problem with Home Depot, however, is that they only sell new or clearance tools. Sometimes the clearances can be absolutely fantastic, but if an item isn’t on sale or clearance, you’re going to be paying full price.

This is because Home Depot doesn’t sell any refurbished tools. They only sell new. If you’re in a pinch (or just have extra cash to spend), that’s perfectly fine. But, if you’re like me and are always on the hunt for the best deal, Home Depot simply isn’t the place to buy Ryobi gear.

Refurbished tools aren’t always available, but when they are, they’re my go-to

I’m a big proponent of buying used, open box, or refurbished gear. I just recently got a new iPad Pro and saved about $150 buying my Magic Keyboard and Apple Pencil Pro used from Best Buy. They were in like-new condition, and I saved a ton of money—what’s not to like?

I’m the same way with tools. If I can find a used or refurbished tool to do the job, I’m going to choose it almost always. You see, refurbished tools can sometimes offer even better quality than new tools. How is that possible? Refurbished products have to go through rigorous testing before they’re able to be sold, while new tools are just manufactured and sold (most of the time).

Used tools are a different story, and a route I only go if the deal is right. With used tools, you never quite know exactly how the tool was treated, so it’s hard to know how much life it has left. However, I was able to pick up a 3-speed Ryobi 18V impact driver for $10 used and that was well worth the gamble for me.

Buying direct from the manufacturer is the best way to save money and shop with confidence

If you’ve never heard of Direct Tools Outlet, let me introduce you to your new best friend. It’s a good thing mine is located about 75 minutes away from me, or I would be there a lot more than once or twice a year.

Direct Tools Outlet is owned and managed by TTI, the parent company of Ryobi (and RIDGID, and Milwaukee, and others). This means that TTI is able to completely sidestep the intermediary and sell tools at a discount directly to the consumer (hence the name).

While Direct Tools Outlet does sell new tools, they specialize in refurbished or used gear. Direct Tools is where I found that $10 impact driver. I also got a refurbished Ryobi electric pressure washer for about $60 a few years ago.

Depending on the tool, Direct Tools Outlet (also known as DTO) even includes a fairly generous warranty with your purchase, especially for refurbished items. This is how I got my pressure washer, and it gave me the peace of mind to save some cash without worrying that the system might break and cost more to repair than I paid in the first place.

If you don’t have a DTO near you, they have an online store with shipping that offers many of the same deals that they do in-store. The main difference is, some stores have local used inventory that isn’t available online, but the refurbished gear is generally available in both locations (online and in-store).


At the end of the day, if you’re on the hunt for discount Ryobi gear, Direct Tools Outlet should be your first stop before you go anywhere else.
