Ever find yourself viewing a webpage when something annoyingly pops up, like an ad, or paywall, or a prompt to sign up for a newsletter? Or maybe you notice that even after the content has loaded, something is still using your network connection? Enter NoJS, a tool that helps you effortlessly, and temporarily, disable Javascript for the page you're viewing. Easily prevent popups, tracking or analytics services, ads, and some paywalls. No need to go into your Safari settings and disable Javascript, only to immediately return to enable to. No need to strengthen content blockers, only to loosen them up again. Just two taps from any Safari view. ** NoJS is NOT a content blocker. It is an extension that works in all apps that allow sending URLs to other apps. This means almost any app that has a way to view webpages, but actual mileage may vary. Also, some pages may appear broken when viewing them without Javascript, but good websites won't :)

Verdict
The clearest difference is price: DMARC Checker at Free against No JS's $2.99. DMARC Checker also leads on update cadence (every 2 days vs every 13 months) and iOS requirement (12.0 vs 15.0). No JS's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
