Excel 2016+ and Google Sheets, no subscription, free v1.x updates. Plain math, not tax advice.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
