Minimal RSS Reader, 4 Feeds
Made for iPhone Duo: headlines and article side by side, and half open 4RSS becomes a receiver. Four feeds, no account, no tracking. from version 2.6
4RSS is a minimalist RSS reader for iPhone with exactly four feed slots. Pick the four sources you really care about, open the app and read. No accounts, no tracking, no endless inbox.
Add up to four RSS or Atom feeds. Each one lives in a slot in the bottom bar with its own icon and an unread counter. Tap a slot to load its articles. Long-press a slot to edit or delete the feed. Choose which feed opens when the app starts. The limit of four is deliberate: it keeps your reading calm.
Tap an article and it opens right away in the built-in browser. Share the link with the iOS share sheet. Pull down to refresh, and see when the feed was last updated.
Articles you open are marked as read, unread ones stand out in the list. One tap on the checkmark marks the whole feed as read. Star articles as favorites and filter the list to see only those. Favorites stay even if you change a feed.
Short on time? Let an AI summarize an article in a few lines, create a short snippet to share, or get a summary of today's or this week's news in the current feed. Summaries are written in the app's language. from version 2.5 You use your own API key from Claude (Anthropic), OpenAI, Google Gemini or Mistral and choose the model. Copy or share the result with one tap. The feature is off until you add a key, and you can delete the saved key for each provider at any time (Remove Key). from version 2.5
No account, no ads, no analytics, no tracking. 4RSS has no server. Your feeds, read status, favorites and settings stay on your iPhone, and your API keys are stored in the iOS Keychain.
To be clear about what the app does contact: the feed servers you add, the websites of articles you open or have summarized, and the website of each feed to load its icon (only that host). from version 2.5 If you use AI summaries, the app asks for your consent once per provider and loads the article pages itself. It then sends titles, dates and article text (for a news summary, up to ten articles plus further titles and the feed name, but no links) to the provider you picked, under that provider's terms. Without a key, nothing is sent to any AI provider.
4RSS speaks English, German, French, Spanish and Italian and follows your iPhone's language. To change it, use the Language row in the app's settings.
Fully open, 4RSS becomes a newspaper. The headlines are on the left, the article is on the right, no going back and forth.
Half open, 4RSS becomes a receiver. Standing like a book, the headlines are on the left and the article on the right. Set up like a laptop, the article stands at the top, the headlines and your four feeds lie below.
Folding keeps your place: the feed, the article and where you are in it, open settings and AI summaries stay as they are.
From robspace: independent app development with a focus on simplicity and privacy.
The limit of four is deliberate: it keeps your reading calm. Pick the four sources you really care about. To change or replace a feed, touch and hold its slot in the bottom bar.
No. 4RSS has no server of its own, no user account, no analytics, no advertising and no tracking. Your feeds, read status, favorites and settings stay on your iPhone. The app connects only to the feeds and web pages you choose and, if you use AI summaries, to the AI provider you select. The details are in the privacy policy.
They are optional and stay off until you add an API key from your own account with Claude (Anthropic), OpenAI, Google Gemini or Mistral under Settings → AI Features → AI Configuration. Before anything is sent to a provider for the first time, 4RSS shows what will be sent and asks for your agreement once per provider. Summaries are written in the app's language. Summaries are AI-generated and may not always be accurate.
Go to Settings → AI Features → AI Configuration and set the provider to “None”. There you can also delete a saved key with “Remove Key”. To revoke a key for good, delete it in your account with the provider.
4RSS follows your iPhone's language. In the app, tap Settings → Language; this opens the iOS Settings for 4RSS. If there is no Language row there, first add the language under General → Language & Region.
No. 4RSS is a paid app; the App Store shows the price for your country. AI summaries use your own API key; API usage may incur costs based on your provider's pricing.

4RSS is made by Robert Poetzsch (robspace.de), who is responsible for this app within the meaning of the GDPR. Contact: support@robspace.de. The postal address is in the legal notice (Impressum) on this website.
In short. 4RSS has no server of its own, no user account, no analytics, no advertising, no tracking and no third-party SDKs. The developer receives none of your data. The app connects only to the feeds and web pages you choose and — only if you switch on the optional AI features — to the AI provider you select with your own API key.
What is stored on your device. Your feeds (name and address, up to four), the links of articles you have read, your favorites (title, link, date, short description and feed name), a cache of recent articles from your feeds (kept for seven days; favorites are kept until you remove them) and your settings (default feed, selected AI provider and model, the AI providers you have agreed to) are stored only on your iPhone/iPad, in the app's private storage. API keys for AI providers are stored in the iOS Keychain on the device and are not transferred to a new device.
Feeds and icons. To show your feeds, the app loads the RSS/Atom files directly from the addresses you entered — when the app starts, when you switch feeds, when you pull to refresh and when you return to the app after more than ten minutes. Feed icons are loaded only from the same server as the feed: first its standard icon file, otherwise the icon named on that server's start page. These servers receive your IP address and technical details such as the app name and iOS version, as with any internet request, and are operated by the respective publisher, whose privacy policy applies. 4RSS only uses encrypted (HTTPS) connections.
Reading articles. When you open an article, the web page is loaded in a browser view inside the app, just as when you visit it yourself. The website may use cookies, analytics or advertising of its own; that is the website's responsibility, and the data it stores stays in the app's private storage on your device.
AI features (optional, off by default). The AI features work only after you select a provider (Claude by Anthropic, OpenAI, Google Gemini or Mistral) and enter an API key from your own account with that provider. Before anything is sent to a provider for the first time, the app shows what will be sent and asks for your agreement once per provider. When you start a summary, the app first loads the article web pages itself from the publishers (for a news summary up to ten, including articles you have not opened) and then sends the following to the selected provider: for an article summary, the article title, publication date and up to about 5,000 characters of article text (about 3,000 for a mini-summary for sharing); for a news summary, the feed name you gave, the period, the titles, dates and up to about 2,000 characters of text of up to ten articles, plus the titles and dates of further articles. The request also names your app language so that the summary is written in it. No links, none of your other feeds and no device identifiers are sent. The request is made with your key, so the provider can assign it to your account, and the provider's own terms and privacy policy apply — including how long it keeps requests and whether it uses them to improve its models. The developer is not involved and has no access. Nothing is sent to an AI provider unless you start a summary yourself. To stop using AI, set the provider to "None" under Settings (gear icon) → AI Features → AI Configuration; there you can also delete a saved key with "Remove Key". A key you do not remove may remain in the device keychain even after the app is deleted. To revoke a key for good, delete it in your account with the provider.
Sharing and links. Copying or sharing an article link or a summary happens only when you tap Copy or Share; you decide who receives it. The community links (GitHub) and the privacy policy link in the settings open your browser only when you tap them; the app itself sends nothing to these sites.
iCloud and device backups. 4RSS has no iCloud sync. Like any app data, its stored feeds, favorites and settings are part of your iCloud or computer backup of the device if you have turned that on. This is an Apple function that you control in iOS Settings.
Your control and your rights. You can edit or delete a feed by touching and holding its icon in the bottom bar, and remove a favorite by tapping its star again. Deleting the app removes the data stored in the app from the device (see above for API keys). Because the app sends the developer no data about you, there is nothing the developer could disclose, correct or delete; questions are still welcome at support@robspace.de. You have the right to lodge a complaint with a data protection supervisory authority, for example the Hessian Commissioner for Data Protection and Freedom of Information (HBDI).
This website. This website is hosted by Hetzner Online GmbH on a server in a data centre in Falkenstein, Germany. When you open a page, the web server automatically logs your IP address, the date and time, the requested page or file, the HTTP status, the number of bytes transferred, the referring page (referrer) and your browser’s user agent. These logs are used solely to operate and secure the website; the legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure, stable operation). They are deleted automatically after 14 days at the latest, are not analysed and are not passed on unless required by law.
The website sets no cookies, uses no analytics or tracking and embeds no content from third parties. Only your language choice is kept in your browser’s local storage, and not for tracking. Fonts are served from this server; no connection is made to Google Fonts or other font services.
Changes. If the app's handling of data changes, this policy is updated and the date above changes.
