1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites. 1Blocker is very easy to use — just flip a couple of switches to start blocking ads and trackers. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. It’s as simple as setting and forgetting. 1Blocker is a fully native app designed to extend Safari naturally. It’s lightweight and doesn’t drain your battery by taking up your device’s resources. The blocking itself is super fast because Safari does it itself. We only provide filters to Safari and don’t modify webpages in any way. This vastly improves efficiency because Safari knows in advance what should be blocked. So, with 1Blocker, sites load on average 2-5x faster. It’s important to note that not all ads can be blocked though. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers. SECURE BY DESIGN 1Blocker is secure and private. It doesn’t have access to webpages and doesn’t track you in any way. We believe that privacy is not for sale. That's why we don't have an "Acceptable Ads" program. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you. ADVANCED CUSTOMIZATION 1Blocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. It also lets you block cookies. (Available in Premium) AVAILABLE ON ALL DEVICES 1Blocker is available for iPhone, iPad, and Mac. Your preferences and custom rules are always in sync through iCloud no matter which device you're using. FEATURED IN THE PRESS 1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more. FEATURES AVAILABLE FOR FREE • The ability to enable one category (for example, Block Ads only) • Whitelisting sites right from the Safari extension • Whitelist synchronization between devices via iCloud FRIENDLY SUPPORT Send your feedback at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release. We have been making 1Blocker since 2015. We believe it’s the best all-around package currently available in the App Store.

Meet Doomwatch - your companion in the eternal struggle against expired certificates and forgotten domain renewals. It's seen things. Terrible things. Like that time legacy-system.company.com went down at 3 AM because nobody remembered the cert expired. Doomwatch remembers. Doomwatch always remembers. Doomwatch is the app for IT professionals who've learned the hard way that certificates expire, domains lapse, and management will absolutely ask "why didn't we know about this?" while you're frantically Googling renewal procedures at midnight. What Doomwatch Does (So You Don't Have To): • Monitors SSL/TLS certificates before they expire and take your infrastructure with them • Tracks domain registration expirations because apparently nobody puts these in a calendar • Sends daily notifications that aggregate all your impending doom into one convenient panic attack • Runs background checks at 8 AM so you can find out your day is ruined before you've finished your coffee • Provides Home Screen and Lock Screen widgets for maximum situational awareness and minimum peace of mind Features That Acknowledge Your Pain: - Certificate Verification: Connects to your servers, inspects their certificates, and judges them for expiring. Color-coded from "you're fine" green to "start drafting the incident report" red. - Domain Expiration Tracking: Uses modern RDAP protocol to check when your domains expire. Because WHOIS is as deprecated as that server you keep meaning to decommission. - Smart Notifications: One aggregated daily notification listing everything that's about to expire. Doomwatch respects your notification hygiene, even if the universe doesn't respect your uptime SLAs. - Widgets Everywhere: Small, medium, large, circular, rectangular, inline—Doomwatch will display your infrastructure anxieties on every available surface of your iPhone. - Grouping & Sorting: Organize servers by domain, sort by urgency, collapse cards when you can't bear to look. Doomwatch understands avoidance coping mechanisms. - Import/Export: Bulk import servers via CSV because nobody has time to type 47 hostnames manually. Export when you change jobs and need to hand this problem to the next person. What Doomwatch Wants You to Know: Doomwatch isn't here to judge. Well, actually it is—he's literally a skeleton holding a warning sign—but he's judging the certificates, not you. When everything is valid, he shows a green checkmark. When things are expiring, he displays the count with the enthusiasm of someone who's seen empires fall over forgotten cron jobs. Download Doomwatch: Because ignorance isn't bliss, it's a P1 incident at 2 AM. Available now. Existential dread included. Stable infrastructure not guaranteed but at least you'll see it coming.

Verdict
The clearest difference is in-app purchases: Doomwatch at none against 1Blocker's 7. 1Blocker's advantage is device support (4 vs 2) and iOS requirement (16.0 vs 26.2). On price and ads there is nothing between them.
