Harbor is a beautiful, local-first read-later app for people who are done losing their reading lists. When you save an article, Harbor keeps a full, clean copy on your device — not a bookmark, the whole thing. It works offline forever, syncs through your own iCloud, and has no account and no server. We can't read your library, can't delete it, and can't be acquired and shut it down. It's just files you own. SAVE FROM ANYWHERE • Share a link from Safari or any app, or paste a URL in the app. • Harbor downloads the page and turns it into a clean, readable article. • Everything you save is yours offline, instantly. A READER YOU'LL WANT TO LIVE IN • Distraction-free typography with light, sepia, and dark themes. • Adjustable font, size, and spacing; reading progress and highlights. PRIVATE, ON-DEVICE EXTRAS — FREE • One-tap summaries and auto-tags powered by on-device Apple Intelligence. • Read-aloud for any article with natural on-device voices. • Instant full-text search across everything you've saved. OWN YOUR DATA, LITERALLY • Export your entire library to HTML and Markdown anytime. • No account, no sign-up, no tracking, no analytics. Nothing collected. ONE-TIME UNLOCK, NEVER A SUBSCRIPTION Save up to 20 articles free. Unlock Harbor Unlimited once for unlimited saves, on-device summaries, read-aloud, and export — a single purchase, yours to keep. Harbor respects publishers: it saves what a normal reader sees, for your own offline reading, and is not for redistribution.
