iPhone
Stacks is a calm, fully offline reader for the newsletters, blogs, and podcasts you already follow.
Add any Substack or RSS feed and Stacks downloads the full articles, images, and podcast episodes to your iPhone so you can read and listen anywhere, even with no signal. On a plane, on the subway, off the grid: nothing buffers, nothing reloads.
WHY YOU'LL LIKE IT
• Truly offline — full article text, images, and audio are stored on your device for reading and listening with no connection.
• A clean, distraction-free reader with adjustable text size, light and dark themes, and a built-in podcast player.
• Smart automatic downloading keeps your latest posts ready and manages storage for you.
• Fast full-text search across everything you've saved.
• Collapsible comment threads, when you want them.
PRIVATE BY DESIGN
Stacks has no servers of its own, no account, and no analytics. Everything it downloads stays on your device and goes nowhere else. No tracking, no ads.
No account is required: just add a feed and pull to refresh.
