About the Tools.us.org score
A weighted average of the published ratings below, shown out of 10 in the header above.
Based on 2 sources, 282K ratings.
How we calculate this
Each source counts by its number of ratings or reviews, capped at 1,000. Score = 2 × sum(rating × weight) ÷ sum(weights), rounded to one decimal. Inputs are published ratings out of 5; a missing source is left out, never counted as zero. A composite of published scores, not our own test.
Included: App Store 4.1 (weight 1,000), Google Play 4.6 (weight 1,000).

How it is counted: fixed keyword rules read each review's text, and no model writes the claims. A review counts once per theme and can mention several. Praise is counted in reviews rated 4 or 5 stars, complaints in reviews rated 1 or 2 stars. The reviews are the 500 that Apple's public review feed returned; the feed returns a window of reviews, not all of them.
