STASH keeps the links, screenshots and places you save for later in one place, and lets you sort them into collections by pushing cards sideways. Use it to save links to read later, organize screenshots, keep a list of places to go and restaurants to try, or gather a wishlist and recipes. Save from any app Tap Share in any app and choose STASH, and a link, photo or place is saved at once. Copy a link, open STASH and tap the plus button at the bottom left to save it. STASH camera and notes The plus button at the bottom left opens the camera and notes. Camera photos and videos go straight into STASH, not your photo library, into the collection you pick. Touch and hold the app icon to open the camera. Notes sit in collections with your links and photos, and search finds them. Screenshots and screen recordings come in by themselves STASH picks up new screenshots and screen recordings from your photo library. It reads the words inside screenshots on your phone, so you can find one by what it says, or select part of it and copy just that text. Photos and videos, a whole album at a time In Choose photos to import, browse your photos and videos album by album, and press and drag to pick many at once. Bring a whole album straight into the Sorter or a collection. Photos and videos shared from other apps are saved too. Map links become places Links shared from Google Maps, Apple Maps, Naver Map or KakaoMap are saved as places with their name and address, shown together on a map, and open in the map app you choose. Sort by pushing cards Everything not yet in a collection waits in the Sorter. Push a card sideways to file it into a collection, or swipe up or down to leave it for later. Filed the wrong one? Tap undo at the bottom left, and set where each push goes at the bottom right. Screenshots can be cropped right there. A lighter photo library STASH keeps its own full-size copy of every photo and video you file, so you can choose to delete the originals from your photo library. Deleted originals go to Recently Deleted in Photos. Live Photos and GIFs keep moving, and you can save any of them back to your photo library from the bottom of its page. You can also delete from STASH only and keep the original in your photo library. When this device is low on storage, the Sorter tells you first, and anything STASH could not copy stays in the Sorter instead of going into a collection. Get it back from the Trash When you delete items or a collection, move them to the Trash and you can restore them for 30 days by default. Choose to keep things 7, 15, 30 or 60 days. Restore a deleted collection whole or just the items you pick, and delete a collection by pressing and holding it and dropping it at the bottom of the screen. Attach straight from your collections STASH shows up in the Files app and in other apps' file pickers, so you can attach photos and videos from your collections to an email or a message. Find and browse Search looks through link titles, the words inside screenshots, places and your notes at once, and searching inside a collection looks only there. Add favorites, tags and notes. Travel, Shopping and Restaurants collections are ready from the start. A nudge when it piles up When the Sorter reaches the number you set, STASH reminds you. Never at night. No account, on your phone No sign-up. Your items are stored on this device and never synced. STASH Pro One purchase removes the ads and opens everything below. It is not a subscription. New photos and videos from albums you choose, brought in automatically File in four diagonal directions in the Sorter Export and import, all at once or one collection Send collections to other people Send links, pictures and addresses from a computer Widgets on STASH's main screen Your full record of what you saved, sorted and opened Available in English, Korean, Japanese, Chinese (Simplified and Traditional) and Vietnamese.
