User Reviews

Users praise Umbra for strong ad blocking that improves Safari performance and provides a seamless, in-background experience. However, repeated concerns include inconsistent blocking across sites, overblocking that disrupts content, interference with page loading, and update-related reliability issues.

Pros

Blocks ads effectively across many sites and often eliminates ads entirely.
Improves Safari performance and overall browsing experience.
Low-friction, in-background operation that users often forget is installed.
Free / lightweight ad blocker delivering strong value.
Significant reduction of intrusive ads on major sites (Yahoo, ESPN, etc.).

Cons

Inconsistent/ineffective blocking on some sites; ads still appear or blocking stops after updates.
Over-blocking content and images, breaking site navigation and readability.
Interferes with Safari page loading or functionality (e.g., dropdown menus not loading).
Update reliability issues; stuck updating or recent releases stop blocking ads.
General errors and reliability issues reported by users.

Recent reviews

This app interfered with normal Safari page behavior on our iPhone. Apple’s Report a Problem page would not load its standard dropdowns until Umbra was disabled. I’m leaving this review so other users know to check their content blocker if important sites stop working.

Just realized this ad blocker was preventing twitter from loading properly on safari on iPhone. XR. Had no idea what was causing it until I disabled Umbra. Everything worked perfectly afterwards.
