Frequently asked questions
How does the App Blocker Finder choose a recommendation?
It gives the most weight to your primary goal, excludes unsupported platforms, and then considers budget and blocking style. Capability scores use a disclosed editorial scale from zero to five.
Does the finder always recommend Journal Lock?
No. ScreenZen can rank first for free controls, Freedom for cross-device blocking, one sec for mindful pauses, and Opal for analytics. Journal Lock ranks first when journaling accountability is the main goal on a supported platform.
Is this an independent comparison?
No. Journal Lock publishes the finder and has a commercial interest in your decision. Source links, reviewed dates, tradeoffs, and the scoring method are public so you can verify the result.
