Memorylens shows you the photos you took on this day, in every year before this one. Open it in the morning. One day, all the way back. What it leaves out Your camera roll is mostly not memories. It is screenshots, receipts, parking signs, and the nineteen near-identical shots you took to get one good one. Memorylens reads all of that and keeps it out. Screenshots are detected exactly, not guessed at. Bursts collapse to the one frame worth keeping. Receipts, documents and photos of a laptop screen get scored and dropped. Photos with people in them rank higher, because those are the ones you stop on. You set how strict the filter is. If something still gets through, hide it, and it never comes back. The bits that matter A reminder each morning, at a time you pick. Any photo hidden permanently, with one tap. Share a memory in a frame that carries the year, or share the photo on its own. Finding today's photos happens on your phone and needs no connection. Honest about your data Memorylens reads the dates on your photos to work out what belongs to today. That runs on your phone. Nothing is sold, nothing is used for advertising, and there is no tracking of any kind. Keep, optional The daily memory is free, every year of it. Keep adds one thing: a copy of each memory saved as it surfaces, so the day is still here even if the photo has left your phone. Delete from your camera roll without losing the moment. A copy is around 1600 pixels wide, right for looking at and sharing, not a replacement for your original. Screenshots and receipts are never uploaded. Keep costs EUR 19.99 a year. It is a yearly auto-renewing subscription: payment is charged to your Apple account when you confirm, and it renews at the same price each year unless you cancel at least a day before it renews. You can cancel any time in your Apple account settings. Requires iOS 18. iPhone only.
