How this is counted
Every number is arithmetic over the reviews we hold, re-counted weekly: nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. Shares are of this app’s own recent negative reviews; the market figure is its rivals with this app excluded. The graded words have fixed cutoffs against the store’s typical rate: elevated from 1.15, high from 2, extreme from 3.5 times it. The page says what is broken and how it compares, never how to fix it, and never whether this app can win.
