Oh man, I've made so much software for my wife and family. She never uses my stuff! First, wouldn't use my math apps for kids (Math Planet, Math Pop, Numbaland) bc she was against screen time. Then, for her, I made a math app that specifically doesn't involve screentime (adaptive practice where parents read out math problems) — and she still didn't use it. My kids like it, in any case: Factflow.io
