Pay once. No ads. Nothing saved. Sporløs is a private browser that leaves no trace. No history, no cookies, no cache: everything you do lives in memory only and is gone when you tap Forget everything or leave the app. INCOGNITO IS NOW SPORLØS If you've used "FREE Private Incognito Browser" ("Color Browser" on your home screen), this is the same app, rebuilt from scratch. Sporløs is Danish for "without a trace". NOTHING IS SAVED • Every tab is private: cookies, cache, site data and history stay in memory and are never saved to your device • Forget everything: one tap closes every tab and throws away the session's data • Forget automatically when you leave the app: right away, after 1 minute, after 15 minutes, or only when you tap • No downloads and no bookmarks, on purpose: they would leave a trace BLOCKS TRACKERS AND ADS • A built-in list blocks common trackers and ads, on from the start • See which trackers were stopped on each page, and how many this session • Known sites are switched to HTTPS YOUR SEARCH, YOUR CHOICE • DuckDuckGo, Startpage, Brave Search, Ecosia, Qwant, Google or Bing • No search suggestions: nothing you type leaves your phone until you send the search LOCKED AND HIDDEN • Lock with Face ID or your passcode, if you like • Always hidden in the app switcher A REAL BROWSER • As many private tabs as you like, with a tab overview • Swipe back and forward, pull to refresh, find on page, request desktop site, share, copy link • Block JavaScript, if you like • Links that would open another app ask first • iPhone and iPad, light and dark mode • English, Danish, Japanese, German, French, Spanish and Korean WHAT IT DOESN'T DO Sporløs keeps your browsing off your device. It is not a VPN: the sites you visit, your network and your internet provider can still see the traffic. NO ACCOUNT, NO TRACKING Sporløs has no account and no server of its own, and collects nothing about you. PAY ONCE. THAT'S IT. Sporløs costs a small one-time price: every feature and every future update, with no ads and no subscription. The extra app icons and a silly little game are included for everyone.

Verdict

The call

The clearest difference is price: Radium Web Browser at Free against Sporløs's $1.99. Radium Web Browser also leads on rating (3.7 vs 3.4) and update cadence (every 11 days vs every 6 weeks). Sporløs's advantage is in-app purchases (none vs 1) and review sentiment (76% vs 50%). On ratings volume, ads, monetization model and device support there is nothing between them.
