Many of you asks me how this application can help or even some of you are saying that it's fake because it does not measure blood pressure. The fact is that there is no smartphone that can measure blood pressure. It is a lot more complicated process than eg. measuring your pulse.
A good start point would be taking your first measurement and record it:
Your recorded data is now stored in the application for you! The more measurements you record, the more accurate the statistics and analysis will be in the app. Read next Help topics and get familiar with basic features and the more advanced ones.
No problem at all! By clicking a menu button you can select "Turn off Advertisements".
This action will shows you a Google Play billing service in which you can perform the payment. Doing that you support my work, these long hours (since almost 2 years) that I spent after my regular work in order to bring you this free, top quality application with unique features :)
Don't worry about the payment, it is safe and I don't persist any data about your credit cards. Every information is handled by Google basing on your account data. Here you can read how to add credit card to your google account.
