## Description

1Blocker is a native Safari content blocker that removes ads, trackers, and clutter without modifying pages. A simple on/off switch lets you start blocking instantly, while cloud-delivered filters update in the background for fast, lightweight browsing.

Premium features unlock advanced customization with regex-based URL blocking and CSS-element hiding, plus optional cookie blocking. Your rules sync across iPhone, iPad, and Mac via iCloud, and the extension prioritizes privacy and security with no tracking and no Acceptable Ads stance.

## Review summary

Users generally praise 1Blocker for strong, system-wide ad blocking and long-standing reliability, especially for Safari. However, recurring issues persist: ads still appear on many sites and YouTube, updates can slow Safari or page loads, and billing/cancellation problems plus premium gating frustrate some users. Overall, the blocking capability is valued, but reliability, performance, and billing concerns significantly affect the experience.

### Pros

- System-wide ad blocking with strong Safari support and tracker blocking.
- Long-standing reliability with a loyal user base and years of use

### Cons

- Inconsistent ad blocking across sites and YouTube, with ads still appearing.
- Safari performance issues after updates, including very slow page loads or pages not loading.
- Billing problems and cancellation friction, including hard-to-cancel trials and unexpected charges.
- Premium feature gating, with some features restricted behind the paid tier (e.g., blocking adult sites).
