Star Hopper — Math Adventures for Kids: Adaptive math adventures kids actually ask to play

Hey PH! I'm Chee, a dad and product manager from the Seattle area. I started building Star Hopper because my kid treated math homework like a punishment. The idea: wrap real math practice inside a story she'd actually care about — a space cadet on a 20-mission adventure. The newest piece is the adaptive engine: it tracks mastery per math skill and adjusts difficulty turn by turn — gentler when a child struggles, tougher when they cruise. All on-device, nothing leaves the browser. Pre-K and 1st grade are live and completely free while we're in beta gathering feedback. No ads, no accounts, no tracking of your child. I'd love honest feedback from parents and educators — especially whether the difficulty feels right for your kids. What would make them actually want to do math?
