Your reading list, not an algorithm's. If you remember the open web before recommendation engines decided what you would read next, Simplio RSS Reader brings that habit back. It is a calm, private rss reader for adults who want to subscribe to the blogs, newsletters and newsrooms they actually care about, then see them in chronological order without ads, without a trending rail, and without engagement traps designed to keep you scrolling. Reading, not feed-doom. The feed reader treats your time as yours: it loads what you subscribed to, in the order it was published, and stops being interesting the moment your inbox is empty — which is the point. Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a 3 day free trial; you may cancel anytime during the trial to avoid being charged. Add feeds by URL or paste in an OPML file from another app, then organise them with folders and tags. The reader app supports RSS, Atom and JSON Feed, articles open in a clean reader mode stripped of clutter, and you can star articles, save them to read later, or search across every feed when you remember a phrase but not the source. Unread counts surface on Home Screen and Lock Screen widgets, full offline reader mode means the subway is a library, and OPML export lets you walk away at any time with everything you ever subscribed to. The blog reader also handles the awkward shape of modern publishing: full-text fetch pulls the complete article when a feed only ships a summary, keyword filtering quietly mutes topics you are tired of and highlights the ones you care about, and background refresh schedules let a heavy news reader update at sensible intervals without draining battery. Per-feed rules can mark a niche developer blog as "always notify" while a high-volume newsroom is held back to a single digest. The atom reader and rss subscription handling supports authenticated feeds where the publisher allows, and PDF article export lets you save a long read for an offline flight or a research archive. Your subscription list and read state stay on this device. There is no account requirement, no analytics following which articles you open, and no third-party server in the loop with your reading habits. The interface ships in 39 languages with VoiceOver accessibility, designed for anyone who missed RSS after it was declared dead, writers and journalists tracking sources, developers following blogs and changelogs, and readers tired of algorithmic news feeds. As a minimal reader, blog aggregator and privacy reader, it hands editorial decisions back to you — what you read, in what order, and for how long is no longer a recommendation. Unlock with Pro: • Unlimited feeds (free tier: 20 feeds) • All widgets, themes and custom reader fonts • Full-text fetch when the feed is truncated • Keyword filtering to mute or highlight topics • Background refresh schedules and PDF article export Subscription Pricing & Terms Features require a subscription.
