I used to like to use Tactio Health App back in the day, before the introduction of the Apple Health Kit.
However, after getting a more modern iPhone and installing it onto it, I realized that despite the fact that Tactio Health was reading tons of data from the Health app, it was only writing weight to it. So all of my details related to blood pressure measurements, blood analyses, et Co were locked-in inside the app and it had no intention to share it.
Scanning the App store for apps that would cover that angle actually lead me to a realization – there are tons of copycat apps with slightly different flavors covering four major directions: workout tracking/guidance, weight loss/gain, periods tracking, and baby-related apps.
All in all, there are no lifestyle tracking apps to keep an eye on your habits and warn when you are getting into a lifestyle that would lead to dire health consequences. And there is even less collaboration between apps that try to do it – and Tactio Health is a case in point.
More interestingly, it looks like there are no market right now for that kind of apps – either the users are already bent on keeping their health intact and don’t need any reminders, or they are so hopelessly behind that the “you are too bad” tone of the current apps is way too discouraging.
At the same time, I can understand the reticence of the users to put their health data out there, in the wild, while knowing that potentially this data can be used to deny them coverage in the future or drive their premiums up.
