Best smart glasses
detector apps
in 2026.
Camera glasses went mainstream, and a small wave of apps followed — each listening for the Bluetooth signals the glasses give off. We make one of them, so read this knowing that. We have tried to be the kind of honest about our competitors that we are about our own limits.
The one thing to know before any list: no app in this category — ours included — can prove someone is recording you. Detection means a matching signal is nearby. Anyone who tells you more than that is selling comfort, not detection.
The field.
| LensSentry | $2.99 one-time · iPhone, plus a free Mac menu-bar build. Radar with three plain states (All clear / Possible / Likely), a session log you can export, mute for your own glasses, and detection signatures that update over the air. The engine is covered by 145 automated tests and has been confirmed against real smart glasses in the field. No accounts, no analytics, nothing leaves the device. |
| Antizuck | $2.99 one-time · iPhone. The most famous app in the category — it reached No. 3 on the US paid App Store chart in July 2026, and it earned the attention: a clean radar screen, proximity and confidence ratings, sighting history, local alerts, everything on-device. Covers Ray-Ban Meta, Snap Spectacles, Echo Frames and RayNeo. Full comparison. |
| Nearby Glasses | Free · Android. The app that started the category — covered by TechCrunch and 404 Media at launch in early 2026. Matches Bluetooth advertising frames against a signature library that has kept pace with new hardware. Android-only, which is the main reason iPhone owners keep looking. Full comparison. |
| Glasses Radar | Free · iPhone and Android. On-device, no account, and unusually candid about its own limits — its site says plainly that iOS restricts scanning to the foreground and that detection is not proof of recording, which we respect. On Android it adds a Wi-Fi layer for glasses that are actively streaming or offloading. Full comparison. |
| The clones | A viral category attracts fast followers, and several similar-sounding scanners have appeared on the App Store. Some may be fine. Before paying, check for the things that are hard to fake: a stated privacy posture, named supported devices, and honesty about what detection can and cannot tell you. |
Pick by what
you carry.
On Android
Nearby Glasses is free and was first, and Glasses Radar adds the Wi-Fi layer. Android also permits background scanning that iOS does not, so either will serve you well. We don't have an Android app yet; when we do, it will be on this page.
On iPhone
Antizuck, Glasses Radar and LensSentry all listen to the same physics. The differences are in what happens after a detection: whether you get a session log you can export, whether you can mute your own glasses, how the app talks about uncertainty, and whether signatures update without an app-store release.
For a fixed place
A front desk, a studio, a clinic reception. Phones sleep; a desktop doesn't. LensSentry's free Mac build sits in the menu bar and, unlike any phone, is allowed to listen for as long as it runs. As far as we know it is the only desktop option in the category.
If you want proof
No app can give it to you. A pair of glasses already paired and sitting quiet on a face can be genuinely silent, and no detector — free or paid — hears what isn't broadcast. Treat every app here as a second opinion, and read how detection actually works before trusting any of them.
Where LensSentry
is different.
Every app above detects. The differences that made us build anyway:
It says both halves out loud
On the radar screen itself: a quiet screen isn't a guarantee, and an alert isn't an accusation. Most detectors hedge their alerts but let a clear screen imply safety. We think the quiet half of the honesty matters more.
A session log that survives
First seen, last seen, peak signal — still there after you stop scanning, exportable if you need to show someone. A detection you can't reference later is just a scare.
Live signatures
When manufacturers change what their hardware broadcasts, our fingerprint list updates over the air — you don't wait for an app-store release. New glasses ship every quarter now; this matters more each one.
Phone and desk
The same tested engine runs on iPhone and Mac. The iPhone app has been confirmed against real smart glasses in the field; the Mac build has been watched hearing 40 real Bluetooth devices.
Try the honest one.
$2.99, one-time. No account, no tracking, nothing leaves your phone — and a straight answer about what it heard, including when that answer is "nothing."
