LensSentry
vs Antizuck.
Two iPhone apps, the same $2.99, the same physics: both listen for the Bluetooth signals camera glasses broadcast. We make LensSentry, so this page has a side. But Antizuck earned its place — it reached No. 3 on the US paid App Store chart, and it did the category a favor by proving people want this.
What follows is the comparison we would want if we were choosing.
Where they agree.
More than either marketing page would suggest. Both scan Bluetooth for signatures of camera glasses — Ray-Ban Meta, Snap Spectacles, Echo Frames and more. Both show detections on a radar-style screen with a proximity estimate. Both run entirely on-device with a one-time price: no account, no subscription, no data leaving your phone. And both live under the same iOS rule: scanning runs while the app is in the foreground. Neither can watch your back from a locked pocket, whatever any screenshot implies.
Where they part.
| Uncertainty | This is the real difference. LensSentry's radar states both halves on the screen itself: a detection is not proof anyone is recording, and a quiet screen is not a guarantee of safety — glasses already paired can sit silent. Every app in the category has these limits. We put them where you can't miss them; press coverage of Antizuck's alerts has called them "anticlimactic" for a reason — the physics under-delivers on the promise of certainty, whoever makes the app. |
| After a detection | LensSentry keeps a session log — first seen, last seen, peak signal — that survives after you stop scanning and can be exported. Antizuck keeps a sighting history you can review in the app. If you may ever need to show a manager, a host, or the police what your phone heard and when, the exportable log is the difference. |
| Your own glasses | LensSentry lets you mute familiar devices — your own pair stays visible but never raises the alarm, so the room isn't permanently "on alert" because of you. |
| New hardware | LensSentry's detection signatures update over the air, verified against the Bluetooth SIG registry and real-world captures — when a manufacturer ships new frames, coverage arrives without an app update. |
| Beyond the phone | LensSentry has a free Mac build for machines that sit still — a front desk, a studio — where macOS allows continuous listening that iOS doesn't. Antizuck is iPhone-only. |
| Fame | Antizuck's, fairly won. No. 3 on the paid chart, coverage from 9to5Mac to Gizmodo. If you want the app your friends have heard of, that's the one. |
| Engineering receipts | LensSentry's engine is covered by 145 automated tests and has been confirmed against real smart glasses in the field. We publish that because it's checkable, and we'd encourage you to ask any detector — ours included — how it was validated. |
Which one?
Choose Antizuck if
You want the category's most famous app, a clean radar, and a one-time $2.99 — and you don't need an exportable log, device muting, or a desktop companion.
Choose LensSentry if
You want the same $2.99 to also buy a paper trail you can export, mute for your own glasses, signatures that update themselves, a free Mac build — and an app that tells you the uncomfortable parts on the screen, not in a help article.
And whichever you pick: read how detection works first. An informed user of Antizuck is better off than a credulous user of LensSentry.
Same price.
More afterwards.
$2.99 one-time on the App Store. No account, no tracking — and a session log you'll be glad exists the day you need it.
