What a great, no-sweat, fast and easy program To use! I downloaded the free version, and upgraded within a short space of time, given how easy it is to use and to take benefit of the additional functions, which are greatly enhanced by the 3D Touch menu. Works perfectly as described. I would LOVE to see support for the Fitbit app, but cant fault the programs features or execution, so it gets 5 stars for delivering on its promises. If, like me, you tend not to drink as much as you should, this app will be a big help!
