Me and @TheRupertDamnit found a digital thermometer on clearance, but when the kid got sick we found out it only works through the app.  So this company will always know my kid's temperature.   No thanks.  It became e-waste.  

 100% agreed. Maybe there is a large body of people who do want this; but if one knows the full story, and is actually an informed consumer, perhaps they would also dodge spyware 🙃
