This app shows so much promise, but unfortunately at this time is limited in capacity. It is simply awe inspiring to take your vitals as simply as you take a selfie. Its truly groundbreaking. Well, it would be, with just a few usability and connectability tweaks.
For instance, not sharing with HealthKit is such a huge negative in my eyes, it deserves a -2 star knock for that alone. I centralize everything in HealthKit and Im sure many users like me as well.
And as other users mentioned, ability to use the better specd back camera to take vitals on people other than yourself is a big neg too. Wouldnt it be incredible for in field clinicians and EMTs to compress some gadgets in their toolkit to an iPhone? Sure thats a little simplistic, but underscores a vision where with intelligent apps, a family can take more control of their health by easily monitoring their vitals on a device that is always with them. That optimistic vision is at this moment in April 2016, deployed as an underwhelming reality. Philips, you are Philips! You can do this right! :-)
