Feeds - the reader that builds feeds and learns your taste, all on your phone. • Turn any website into a feed - even ones with no RSS. Feeds reads a page's actual structure to find the articles, so you can follow your kid's school site, your local team, or a blog that's never heard of RSS. Standard RSS, Atom and JSON Feed work too, of course. • A real on-device AI, not a filter list. Mark articles good or bad (or just keep reading - it notices) and an on-device model reorders what you see next. It's the same engine behind your main feed, your daily push, and your widget - one brain, not three separate gimmicks. Traditional group-by-source included too, of course. • Actually private, not just "AI-labeled." The model that learns your taste never leaves your device - no analytics, nothing. • One push a day, hand-picked by your AI - not "top stories for everyone," top stories for you. • A home-screen widget curated by that same AI, always current. • Mute topics instantly - no waiting around for an algorithm to catch on. • Full-text search that's actually instant, across your whole archive. • Full-article offline downloads - read on a plane, underground, wherever. • Read inline, then just keep scrolling. New articles always land below, never on top, so you never lose your place or need to pull-to-refresh. • Free to download. Unlock premium features if you want them, or use it free forever. No account required. The app is a free download with many features included! You can unlock all remaining features with a one time purchase OR a subscription: • The subscription is called 'Premium Monthly' and it will renew on a monthly basis • Payment will be charged to iTunes Account at confirmation of purchase • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period • Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal • Subscriptions may be managed by the user and auto-renewal may be turned off by going to iCloud's Account Settings after purchase Read the app's terms of use: https://feeds-app.com/eula.html Read the app's privacy policy: https://feeds-app.com/privacy.html
