A kids’ app built to be put down
After 13 years building apps that keep people engaged, I made Denny for my son. It’s a quiet maze app where children can work through a puzzle at their own pace, without rewards or animations pushing them to keep playing.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
