think renders news the way e-ink renders a page: soft greys, a serif headline, dithered photographs, nothing that blinks, auto-plays, or refreshes itself while you're looking at it. ONE STORY AT A TIME No infinite scroll, no feed to doomscroll through. Each story fills the screen — headline, photo, publisher, and a read-time estimate. Swipe up for the next one, swipe right (or tap) to open the full article in-app. When you've seen everything your topics have to offer, the feed says so and stops, instead of padding itself out with filler. PICK YOUR PUBLISHERS, SKIP THE ALGORITHM There's no engagement-driven ranking deciding what you see. Choose your topics, and think shows you a curated catalog of publishers behind them — 208 publishers across 32 topics at last count. Vote a story up or down to tune the mix, or mute a publisher outright. Want a source that isn't in the catalog? Paste any site's RSS or Atom feed URL and think adds it to your list. SAVE FOR LATER Bookmark anything you don't have time for now. Saved stories are grouped by topic and stay in your list until you clear them. NO ACCOUNT, NO TRACKING There's no sign-in and no user id. think has no analytics, advertising, or crash-reporting SDK, and no server of its own — it only talks to your chosen publishers' RSS feeds and their image hosts. Your topics, your publishers, your votes, and your saved stories live on your device only, and are deleted when you delete the app. Available in English and Vietnamese. Requires iOS 15 or later.
