Calculator downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Google Play shows an exact lifetime install count; downloads per day are its daily change (measured). When Play hasn't refreshed the count, they come from new ratings and Top Free chart positions. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.
In-app revenue
Worldwide, what users spend in Calculator before Apple and Google take their fee.
How this is calculated
Not in an overall Top Grossing chart, only in category charts: each category position is converted to the overall position it corresponds to, then priced on the same rank-to-revenue curve, inside the part of each market the charted apps leave over.
Business model: Ad-led
How Calculator makes money: subscriptions, one-off purchases and ads.

Review momentum
81/100
faster than 96% of Education apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
