![]() ![]() However, 1Blocker users might not find it necessary. Backed by Adblock Plus and others, Acceptable Ads allows ads that conform to certain guidelines. You can, however, whitelist a site from the Safari Share Sheet.Īs of this writing, 1Blocker does not have an option to whitelist ads approved by Acceptable Ads. Unfortunately, 1Blocker doesn't include a tool for reporting broken sites, as Crystal does. While battery life is important and trackers and the sale of user data are definitely an intrusion of privacy, testing these features is beyond the scope of this review.Īs handy as ad blockers are, they sometimes mess with the structure of websites, causing them to not load properly or at all. Many ad blockers claim to improve battery life and protect your privacy by preventing data-hungry trackers from monitoring you online. If you opt to pay for its extra powers and enable all of them, the effect is even more dramatic. But looking over my tests, 1Blocker beats out the competition, even if only by a small margin, in every category. It's difficult to compare ad blockers, since websites frequently vary the page elements, ads, and trackers they load. With all of 1Blocker's blockers engaged, Safair loaded only 44 resources and 1 cookie, packed into a 3.5MB site that took a mere 1.9 seconds to load. In its default configuration of only blocking ads, 1Blocker cut that number to 95 resources and 2 cookies in a 4.5MB site that took 3.1 seconds to load. Without 1Blocker running, CNN loaded a considerable 189 resources and 7 cookies resulting in a 6.5MB site that took 5.4 seconds to load. I observed similar results on the CNN.com mobile site. 1Blocker reduced website size by 46.4 percent in my testing, and it reduced load times by a whopping 62.9 percent in this configuration. I expected that the resource savings from this configuration with the $2.99 in-app purchase activated would be even more dramatic than simply blocking ads, and that was mostly true. 1Blocker also blocks most cookies, and in my testing loaded 81.1 percent fewer cookies.īut 1Blocker isn't really about just one blocker, it's about using all of those blockers together. How fast? With 1Blocker, loading pages took 45.6 percent less time. Fewer resources means that your phone has to download less data (about 43.7 percent less data, in this case) and pages load faster as a result. Resources include items like fonts, images, and so on. With 1Blocker in its default configuration of only blocking ads, I found Safari loaded 48.1 percent fewer resources on, my test site, than it did with no ad blocker. For a test page, I use PCMag's mobile site, which I reload several times without using cached data.įor this test, I used an iPhone 6 Plus. This way, I can view the entire structure of webpages on my phone, as well as other vital statistics, just like a desktop browser's Web inspector. Using 1Blocker To test iPhone ad blockers, I use the Safari developer tools on both the iPhone and a new iMac. A $2.99 in-app purchase lets you unlock the ability to turn on multiple blockers. Unfortunately, you can only activate one of these additional blockers at a time. ![]() Is there a catch? This is a free mobile app, so you know there is. This is a very cool feature, though one that is poorly documented. Even more complicated, but perhaps more powerful, is the ability to assemble a custom package of blockers on the 1Blocker website and upload it to your iPhone. There are also blacklists for blocking specific URLs, cookies, and CSS page elements. Think of it as leaving some money in the tip jar for sites you want to support. ![]() If you really want to get specific, you don't have to scroll through 4,000 entries to find the one you want.īelow all of this is a user-configurable whitelist for sites whose ads you do not want to block. Don't worry, each section has a search tool. ![]() Trackers, for example, has nearly 4,000 entries. Each option can be expanded, letting you block specific ad networks, trackers, and so on.
