Camera glasses announce themselves over Bluetooth. ZuckOff listens for those announcements and tells you when a lens is in the room. ■ What it spots • Ray-Ban Meta and Oakley Meta, by the manufacturer signature in their Bluetooth advertisement • Snap Spectacles • Display glasses and headsets, including Quest and Vision Pro, are named in the log but never flagged: a headset is a camera you can see coming • The full list, and how each one is recognised, is in the app ■ The evidence, shown • Every flag lists what matched, whether that was a manufacturer ID, a service UUID or an advertised name • Confidence is rated low, medium or high, and the app says which • You can disagree with it, because the reasoning is never hidden ■ Every device, logged • History keeps a record of every Bluetooth device heard nearby, glasses or not • A signal timeline for each device • Own a pair yourself? Mark them once and they stop raising alerts ■ Reports from people nearby • Spot a pair? Tap Report in the Reports tab, and ZuckOff users within 500 m are told for the next 30 minutes • Turn on Alerts from people nearby in Settings to hear about reports around you. Reporting and alerts are free • Busy areas: turn on Warn me in busy areas to hear when you arrive where glasses were reported again and again this week. Also free • Pro adds a map of reports around you with the busiest areas of the week shaded, and a reach of 250 m or 1 km ■ On Apple Watch • Check around me scans from your wrist for fifteen seconds and shows the same evidence as the iPhone • Meeting mode, part of Pro, keeps scanning until you tap Stop and buzzes when a pair turns up • The watch listens only while ZuckOff is open on its screen • With Pro, a watch face can show the last verdict from your iPhone ■ Shortcuts and Siri • Start scan, Stop scan, Get scan status and Get suspect count work in the Shortcuts app, in automations and with Siri • An automation can stop the scan when you get home, even with ZuckOff closed, and start it again when you leave ■ How close, not which way • Signal strength gives a rough distance and no direction at all • ZuckOff shows proximity bands rather than an arrow, because an arrow would be invented ■ What it cannot do • Glasses advertise loudest while powering on, pairing, or leaving the case. Once paired to their owner's phone they can go quiet, so silence here does not mean nobody is recording • A detection does not mean anyone is recording either. ZuckOff sees that a device is nearby and nothing about what its owner is doing with it ■ Your data • No account, no analytics • The log never leaves unless you export it yourself, or choose to send a hardware report for a device ZuckOff does not recognise • A report shows you exactly what it contains before anything is sent • Reports from people nearby are the one feature that uses your location. It is rounded to about 100 m and leaves the phone only when you send a report or turn on their alerts • Your iPhone shares its last verdict with your paired Apple Watch and nothing else ■ ZuckOff Pro Scanning is free and always will be. Pro is for the times you are not looking at the screen: background monitoring, alerts, the Live Activity, the Home Screen widget, meeting mode and the watch face on Apple Watch, history beyond 24 hours, and CSV export. $9.99 per year, with the first week free. The subscription renews automatically unless it is cancelled at least 24 hours before the period ends, and renewals are managed in Settings on your device. A lifetime option is also available: one payment, no subscription, Family Sharing on. One purchase covers iPhone, Apple Watch and ZuckOff for Mac, which is on the Mac App Store. ZuckOff is an independent app and is not affiliated with, endorsed by or connected to Meta Platforms, Luxottica, Ray-Ban, Oakley or Snap.

NO PAYWALL. Declutta is a free iPhone storage cleaner that helps you reclaim space without a subscription or paywall. Your storage is full, and it is not your fault. Every burst, every screenshot, every 4K video adds up until iOS starts refusing to take the next photo. Declutta finds the clutter hiding in your camera roll and helps you delete it - fast, in bulk, and without ever uploading a single image. Find duplicate photos Declutta scans your library and groups every duplicate together. Copies saved twice from messages, AirDrops of photos you already had, screenshots of screenshots - all found, all grouped, all ready to go. One tap keeps the best copy and clears the rest. Find similar photos You took eight shots of the same sunset. You need one. Declutta groups near-identical photos so you can keep your favorite and delete the rest in a single action, instead of scrolling through an album one photo at a time. Compress large videos and photos Large videos are the biggest win on almost any iPhone. Declutta finds them, shows you exactly how much each one is holding, and compresses them to 1080p, 720p or 540p - the video stays in your library, just smaller. Photos compress too, with dates, locations and album membership preserved. Clean the clutter you forgot about • Screenshots - receipts, memes and boarding passes from last year • Screen recordings - they can take up a surprising amount of space • Bursts - keep the best frame, clear the other thirty • Blurry photos - the ones that never came out • Selfies - review a year of them in one place • Live Photos and spatial photos - drop the motion or 3D, keep the photo Merge duplicate contacts The same person saved three times? Declutta finds contacts sharing a name, email or number and merges them into one card, keeping every detail. Swipe to clean Quick Clean turns tidying up into something you can do in a queue. Swipe left to bin a photo, right to keep it. Nothing is removed until you confirm the whole batch, so you can go fast without worrying. Filter down to what matters Sort by size to find the space hogs first. Filter by date, by a specific month or year, or narrow a list to photos or videos only. Open any photo full screen and pinch to zoom before you decide. Track your progress Declutta counts every gigabyte you reclaim and turns it into milestones - from your first cleanup to a whole month cleared. The storage ring updates as you go, so you can watch the space come back. Private and secure by design • 100% offline - the entire scan runs on your iPhone • No uploads, ever - nothing is sent to a server • No account, no sign-up, no email required • No tracking, no ads, no data sold or shared • Deleted photos go to Recently Deleted, so you can always change your mind Declutta cannot look at your photos. Not because we promise not to - because there is nowhere for them to go. Built for iPhone Native and fast on iPhone and iPad, with a Home Screen widget. Works with VoiceOver, Voice Control, Larger Text and Reduce Motion. Dark mode included. Available in 26 languages. Free, no paywall Declutta is completely free to use.
