About this app
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.…

Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.

“Great experience — It’s honestly been a great experience over the past year. The in app blockers also work on certain apps for those annoying pop up adds. I read comics often and even in app it gets rid is the annoying adds in between…”
