Saved a Reel, a TikTok or a recipe and never went back to it? Stash is a bookmark manager for links from Instagram, TikTok, YouTube, X, Reddit and the web — and it brings your saves back so you actually use them. Save from the Share menu and see everything with thumbnails. Every day, one save you haven't opened yet waits at the top of Stash. Free for your first 100 saves. No sign-up, and your library syncs with iCloud. Stash keeps the link, title and thumbnail — it doesn't download videos, so it barely uses storage. ■ Save in two taps Tap Share, choose Stash, done. Works with Instagram (Reels and posts), TikTok, YouTube and Shorts, X (Twitter), Pinterest, Threads, Reddit, Facebook, LinkedIn, Medium, Bluesky and any website. Titles and thumbnails are added automatically. ■ Today's Pick: one save a day Your saved folders in Instagram and TikTok never remind you. Stash does: every day it picks one save you haven't opened yet and puts it on your Home tab and your widget, with a reminder on the days you choose. Open it, snooze it, or skip it — "watch later" finally happens. ■ Daily review & weekly recap Five saves a day, picked from your oldest unopened ones — small enough to finish. A weekly recap shows how much you saved vs. actually revisited. ■ Collections & tags Recipes, restaurants, travel spots, outfits, gift ideas, tutorials — organize your saved posts by theme and find them in seconds. ■ Places on a map Share a Google Maps or Apple Maps link and it's saved as a place, with a map preview and the distance from you. ■ Search & Discover Search by title, site or creator, and browse everything from the Discover tab. ■ Widgets, Siri & Shortcuts Today's Pick on your Home Screen and Lock Screen. Ask Siri to open it, or to surprise you with a random unopened save. ■ Reminders Set a reminder on any save for when you'll have time, plus gentle nudges on the days you choose. ■ No account, your iCloud No account to create. Your saves live in your own iCloud and sync across iPhone and iPad. ■ Made for you if… - You save Reels and TikToks, then forget them - Your "read it later" and "watch later" lists keep growing - You screenshot things or text links to yourself and never find them again - You're looking for a new home for your bookmarks after Pocket shut down 【Free plan】 Up to 100 saves, 5 collections and 5 tags, with ads.
