AdZero vs Denpa Network Check

Focus on the page, not the ads. AdZero is a Safari ad blocker for iPhone and iPad. Reduce banners, unexpected popups, web trackers and other distractions. Preventing blocked ad resources from loading can also help reduce unnecessary data use. ONE PURCHASE. NO SUBSCRIPTION. Use AdZero without creating an account or paying a recurring subscription. CHOOSE WHAT TO BLOCK • Safari ads and advertising popups • Web trackers and analytics scripts • Regional filters for Korean websites • Cookie banners, subscription prompts and other annoyances • Per-site exceptions and custom blocking rules • A Safari helper and an element picker to hide unwanted page elements • Filter updates, protection diagnostics and site issue reports OPTIONAL ENCRYPTED DNS Choose public DNS presets from providers such as Cloudflare and Quad9. Depending on the provider and preset, these can block known malicious domains. This is an optional iOS system DNS setting—not a VPN or AdZero-operated system-wide ad blocker. YOUR BROWSING HISTORY STAYS OFF ADZERO SERVERS AdZero contains no advertising or analytics SDK. It does not send visited website addresses, search terms or browsing history to AdZero servers. Settings and blocking statistics stay on your device. Filter updates download from a GitHub CDN. If you enable encrypted DNS, DNS queries go to your selected provider and its privacy policy applies. BEFORE YOU START • Enable the AdZero content blockers and Safari helper in iOS Settings, then grant the necessary website permissions. The app walks you through setup. • Safari protection does not remove every advertisement inside other apps. • Blocking results vary by website and advertising method. If a website does not work as expected, add it to your exceptions. • DNS protection is optional and does not guarantee that every threat will be blocked. Need help?

Wi-Fi feels slow, but you cannot tell why. Denpa measures what is actually happening, so you can see which side the problem is on. Denpa measures response time, packet loss, download and upload speed, and DNS lookup, and splits your connection into two segments. ■ Two segments, measured separately ・Your device → the first device that responds (your router, or the carrier gateway on a cellular connection) ・The first device → the internet Video stalls. Pages do not open. Experience alone does not tell you whether the cause is inside your home or beyond it. Measuring the two segments separately narrows it down. ■ What it measures ・Response time ・Jitter ・Packet loss ・DNS lookup time ・Download and upload speed (upload requires a server that supports it) ■ It measures only when you tap Nothing is measured until you tap Start diagnostics. There is no background monitoring. ■ Findings come with what to do Issues are listed as Error, Warning, or Information, with why they were flagged and what you can try. ■ Measure how a web page loads Your line is fast, but one page still feels slow. Enter a URL and Denpa loads that page the way a browser does, then reports the load time, the amount transferred, and the speed over that period. The cache is emptied before every run, so measuring the same page twice does not change the conditions. The page stays on screen, and tapping a link in it measures that URL. ■ Save a location, watch it change Name a location and save the result. History shows a chart and a list for each location, and compares the averages. ■ What this app cannot do ・It cannot change your router settings. It narrows down the cause. ・It cannot measure other devices. Everything shown is seen from this iPhone. ・It cannot show signal strength (the bars). Only apps individually approved by Apple can read it. ・It does not make your connection faster. It is a tool for measuring and narrowing down. ■ Privacy ・Results, location names, and notes stay on your device. ・Nothing is sent to the developer or to a third party. There is no analytics, advertising, or tracking. ・Location is never recorded or sent. It is used only to show the name of the Wi-Fi network (SSID), because iOS requires location permission to read it. ・Measuring uses real network traffic. The speed test connects to Cloudflare by default, and you can change the server in Settings. The full list of destinations is in the privacy policy. ■ Requirements iOS 18.0 or later / iPhone, portrait only / Japanese and English Free. No in-app purchases, no ads, no account.
