AdBlocker Ultimate vs AdLock

AdBlocker Ultimate blocks ads and trackers in browsers, apps and across devices, with products for Windows, Android and iOS as well as browser extensions. Its Windows app adds system-level ad and tracker blocking, phishing protection and customizable exceptions. Android offers system-wide filtering, per-app controls, malware and phishing protection, custom filter rules and encrypted DNS, including DNS-over-HTTPS, DNS-over-TLS and DNSCrypt. The iOS product blocks ads, malicious domains and trackers in Safari and supports custom filters and a whitelist. Browser extensions are listed for Chrome, Firefox, Opera, Yandex and Edge; they do not use a predefined acceptable-ads list. The maker says filtering is processed locally and browsing history is not tracked. A free plan and 14-day trial are available. Listed yearly plans cost $39.99 a year for either 3 or 10 devices; lifetime licenses cost $99.99 as a one-time purchase for either device count.

AdLock blocks ads and helps filter tracking and malicious activity across Windows, macOS, iOS and Android, with Android TV also listed. It blocks ad types by default and does not participate in acceptable ads; users can allow ads on selected websites or apps. Other protections include blocking tracking scripts, malware, malicious requests and redirects, plus filtering HTTP and HTTPS connections. Users can add custom filter lists and block cookie popups. Browser coverage includes Chrome, Safari and Firefox, as well as major browsers generally. AdLock says it uses few device resources, can save mobile data and can extend battery life. Free browser extensions are available, and standalone applications offer free trials. The free plan and paid options coexist: plans are $9.95 a month, $39.50 a year, or $15.99 a year when billed every five years. Paid plans cover five devices and include a 30-day money-back guarantee. The company lists 24/7 technical support and is based in Bratislava, Slovakia.
