This is a very broad generalization that doesn't actually seem to be accurate. We know that there are benefits to tracking your blood pressure at home, for example[0]. In addition, and closer to the topic in the original link, there are simply concrete benefits (ie: birth control) to an app like Natural Cycles[1], which involves tracking your temperature and period in an app. I understand that for some people this type of additional option may be difficult to appreciate, especially if you're not a potential user. It requires a lot of discipline: taking your temp consistently and at just the right time. But for women who might not be interested in or respond well to hormonal birth control, it can be an invaluable tool. Even for normal period tracking apps: tracking one's period _can_ be useful. It can help to monitor fluctuations that would otherwise easily go unnoticed for longer than they need to. I've had friends who missed very early or late periods for months before they realized their schedule was off and that it might be something they should see a doctor about. In conclusion, this "all apps/tracking health data is useless" sentiment that gets thrown around so commonly does not really seem to be in touch with reality.
