📝 About this app
Parents, are your kids going to outgrow you?
Kids, are you going to be taller than your parents or your older brothers and sisters?
If so, when will you pass them up? Size Me Up predicts your height at any future age.
First, see how you or your kids' height compares to Americans of the same age and gender. Specify the person's current height, current age and gender to get his or her "percentile ranking."
The percentile ranking shows how the person sizes up to others. For example, a 10-year-old boy who is 4ft 9in is at the 82nd percentile.… View full description on the official store →

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
About this analysis
Why low confidence: only 44 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
