Read without the noise. SereneReader is a calm, native RSS reader for people who want to read — not manage notifications. No ads, no algorithms, no AI summaries you didn't ask for. Just your feeds, in a quiet interface built around the text. WORKS EVERYWHERE, IN SYNC Native apps for iPhone, iPad, Mac, and Apple Watch, plus the web at serenereader.com. Star an article on your phone and it's already starred on your Mac — reading state, feeds, and folders sync across every device in real time. CALM BY DESIGN The interface feels like a quiet room. Articles open in a clean reading view, and a focused mode strips everything away except the words. Adjust font size, line height, and content width to taste. Hand-tuned themes — including the easy-on-the-eyes Jade Night — make late-night reading comfortable. READS WELL OFFLINE Articles are cached on device. Read on the train, star and mark things as you go, and every change syncs when you're back online. YOUR READING, YOUR RULES Organize feeds into folders, search everything, and browse a curated Discover catalog to find new feeds when you want them. Import and export your subscriptions with OPML. Nothing is pushed on you: no streaks, no badges, no "we noticed you haven't opened the app." Full keyboard navigation on Mac and iPad; swipe actions on iPhone. FREE TO START Free to download and read. An optional Pro upgrade unlocks higher feed limits, every theme, and API access — no credit card to get started, no trial that quietly locks you out. Sign in takes seconds: a code by email, or your Google, GitHub, or Apple account. No passwords to remember. Terms of Use: https://serenereader.com/terms
