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.

Verdict
The clearest difference is in-app purchases: Sonar at none against think's 1. Sonar also leads on ratings volume (30 vs 2) and iOS requirement (13.4 vs 16.0). think's advantage is ads (none vs shown) and update cadence (every 2 weeks vs monthly). On price, rating and device support there is nothing between them.

On the App Store both sit at effectively the same score — 4.9 for Sonar against 5.0 for think. That said, the two scores are not equally well evidenced: Sonar has 30 ratings behind it against 2, so its average is the more settled of the two.
Sonar ships an update monthly, think every 2 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
