AdSpamBlock is a made-in-Japan ad blocker and spam detector. It frees you from phishing ads and annoying ads, in Safari, Chrome, Mail and your other apps. STILL SEEING ADS? TURN OFF CONNECTIVITY ASSIST - Why it happens: when Connectivity Assist (formerly Wi-Fi Assist) is on, iOS can switch your traffic to cellular data while Wi-Fi is unstable, and that traffic bypasses ad blocking - How to fix it: go to Settings > Wi-Fi > Connectivity Assist and turn it off. You can also turn it off only for the Wi-Fi network you use - AdSpamBlock warns you: when it detects this setting, the app lets you know on the Home screen and with a notification. You can run the check again anytime from Status > Check again for bypass - Some ad networks may not be blocked: if ads keep appearing on a specific site, you can add it to your blacklist KEY FEATURES - One-tap protection: turn AdSpamBlock ON or OFF from the Home screen and see at a glance whether you are protected - Wide filtering coverage: blocks ads in the background, not only in browsers such as Safari and Chrome but also in Mail and other apps - Protection from harmful and spam ads: filters phishing ads and spam ads, so you are less likely to land on harmful pages - Monitors ads and unauthorized tracking: beyond ads, it monitors and blocks tracking code that runs behind websites without your consent - Block history: see which domains were blocked, how many times and when - Web tracking detection history: see which tracking domains were detected, how many times and when - Whitelist and blacklist: add a site to your whitelist to let it through, or to your blacklist to always block it - Check that it is working: the Status screen in Settings shows whether ad blocking and the VPN connection are working, when the block list was last updated and how many sites you allowed - Update and check in one place: update the block list and check again for bypass right from the Status screen NOTES - Because all traffic is filtered, the iOS data usage screen attributes the data usage of all apps to AdSpamBlock - If Instagram shows an error, try deleting and reinstalling the Instagram app - Requires iOS 15 or later Subscribe to access the app's premium features.
