Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
Child developmental milestones from 18 months to 8 years. Older milestones will be added as they are ready. These are the child developmental milestones as found at The Observant Mom website but now in calendar form! Parenting Tips now added!
These milestones are the notorious “stages” or “phases” that children go through. These are those times when children “act up,” but it’s because new skills are emerging. This work documents both what the irritating behavior is and what the new skills are. Simply enter your child’s due date into the app, and a calendar is generated with their expected developmental milestones. Simply click on any colored date and get instant information about your child! Add as many children as you want. Add as many children as you want.
Countless have said that this work helps them stay patient as a parent or caregiver. Be sure to share this information with family and friends.
