Sentinel Origin
Read full descriptionHide full description
Sentinel Origin gives your valuable items a proof of ownership record you can show to a buyer. Register a phone, laptop, tablet, camera, drone, console, power tool, trade equipment or bike using its serial number or IMEI. Add photos, a description and a receipt if you have one. Every seller verifies their identity with a government issued photo ID and a live selfie, so the record carries real weight. Once registered, your item has its own logbook page. Share the public link in your listing or send it straight to a buyer. They can see the item details, the ownership history and that the seller is identity verified, before any money changes hands. When you sell, ownership transfers cleanly. Enter the buyer's email, they accept the transfer, and the record moves to them with the history intact. No paperwork, no disputes about who owned what. Why it matters. Second hand buyers are cautious, and rightly so. Tools and equipment get stolen and resold constantly. A verified ownership record removes the doubt, helps you sell faster, and gives the buyer confidence they are dealing with an identity verified seller. Features Register items by serial number or IMEI Identity verified sellers Public logbook page for every item Clean ownership transfer to a buyer Full ownership history retained Trusted contacts for arranging a safe meeting Photos stripped of location data automatically Pricing Registration is priced by the declared value of the item. Under £500 is £4.99, £500 to £1,000 is £8.99, and over £1,000 is £16.99. An optional Annual Plan is available at £39.99 a year for unlimited registrations and free transfers. Sentinel Origin is a record keeping service. It is not a stolen goods register and it is not a safety or security service.

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.
