User Reviews

Reviewers praise CheckFirm for its ad-free experience and promising concept, but reliability is a major issue. Many reports show the app stalling on splash screens, crashing, or not functioning after updates. The update flow is broken with phantom prompts, and data/Info Catch features often fail to update or notify. Compatibility with newer Android/One UI versions is repeatedly problematic. There are also trust concerns due to unmoderated user-submitted content. Overall, a strong concept and clean experience marred by stability and update issues.

Pros

Ad-free experience (no ads).
Promising concept/idea with positive sentiment when functioning.
Overall positive sentiment and encouragement from users (e.g., "great app", "awesome, keep it up").

Cons

Frequent instability: app often doesn't work, bugs, crashes, or is stuck on splash screen.
Broken update flow: phantom update prompts, updates that aren’t available or can’t be installed, and splash-screen hangs.
Compatibility issues with newer Android/One UI versions (Android 16/One UI 8) requiring updates.
Info Catch and related data/notification features fail to update or work properly.
Content moderation/trust concerns due to unmoderated user-submitted content and reports being ignored.
