Block ads, trackers, and cookie banners in Safari. See exactly who tried to track you with daily intelligence reports no other blocker provides. WHAT MAKES ADERASR DIFFERENT? Most ad blockers show you a number. AdErasr shows you a story. Your Daily Intelligence Report reveals which companies tracked you by name. Google across 12 sites. Meta on 8. Criteo on 6 you've never heard of. Every site gets a privacy grade from A to F. Tap any site to see a full report card: which tracker families were present, what categories of data they collect, and how that site compares to average. Over 100 tracker companies identified. Not just blocked. Named, categorized, and explained. WHAT WE BLOCK • Ads, banners, pop-ups, and video pre-roll • Trackers, analytics, and fingerprinting scripts • Cookie consent banners (auto-rejected, not just hidden) • Crypto miners, malware, and phishing domains • Newsletter pop-ups, app install nags, and sign-in walls • Anti-adblock detection walls HOW IT WORKS Six independent shields run in Safari: Ads, Security, Privacy, Tracking, Annoyances, and Custom. Toggle any category without affecting the others. Updated automatically so you're always protected against the latest threats. BLOCK ELEMENT: TAP TO HIDE See something you want gone? Tap Block Element in the Safari extension, then tap any element on the page. It dissolves with a satisfying animation and stays hidden forever. Swipe up or down to expand or narrow your selection. Hide multiple elements in one session. Powered by the same CSS rule engine as our filter lists. SAFARI EXTENSION Tap the AdErasr icon in Safari's toolbar to see what's been blocked on the current page, toggle protection for any site with one tap, and get back to browsing. Blocked items are grouped by domain with clear labels so you always know what was stopped and why. WIDGETS Drop your block count on your Home Screen or Lock Screen. Widgets update throughout the day so your protection stats are always one glance away. BUILT FOR PRIVACY No account. No data leaves your device. No "acceptable ads" program. Everything runs locally. Your browsing data is never accessible to us. ALSO INCLUDES • Per-site whitelist with iCloud sync • Custom blocking rules with full syntax support • Home Screen and Lock Screen widgets • 80 achievements across 10 XP levels • Cookie auto-dismissal for 50+ consent platforms • Anti-adblock countermeasures • Weekly privacy digest notification • 10 languages: English, Spanish, French, German, Japanese, Chinese, Portuguese, Korean, Hindi, and Arabic THINK YOUR CURRENT BLOCKER IS GOOD ENOUGH? Visit aderasr.com/test. Our 28-level stress test uses real tracking probes, and most blockers fail before they're halfway through.

Verdict
The clearest difference is price: Coverage Map at Free against AdErasr's $4.99. Coverage Map also leads on rating (4.7 vs 4.3) and ratings volume (817 vs 6). AdErasr's advantage is ads (none vs shown) and review sentiment (100% vs 68%). On in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Coverage Map is free to download; AdErasr costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Coverage Map holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Coverage Map has 817 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 68% of Coverage Map's written reviews are positive against 100% of AdErasr's, so the app with the better star average is not the one people write more warmly about.
Coverage Map ships an update fortnightly, AdErasr every 3 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
