Every complaint across calculator apps, frequency-ranked from real App Store reviews — the gaps nobody on this shelf has fixed.
Read the calculator apps reportEvery 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 shelf 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.
