Photovoltaic Calculations 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.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
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 Photovoltaic Calculations before Apple and Google take their fee.
How this is calculated
Not on any Top Grossing chart: monthly active users × spend per user for its category, measured on the charted apps nearest the bottom of the charts.
Business model: In-app purchase-led
