I don’t understand why I have to give my phone number just to try out the app. I only want to see whether the measurement of vital stats works as advertised, mostly out of curiosity. Ideally, I wouldn’t even want to make an account for that but I would do it if I wasn’t required to give you my phone number. Really, there is no benefit to the user, I can only imagine you’re doing it to collect personal data for future use.
