I like to share some pleasant experiences I have with a phone-based App, doctogram, which when working with the bluetooth enabled vital monitoring devices, automatically collects, records and tracks the results. Although it is capable much more, currently I am monitoring only three vital signs twice a day as I need them to help setting up my home dialysis machine. I found that my weight history, with its visual display, especially helpful in my selection of kind of dialysis solutions to use. I have been able to maintain a more consistent body weight with just this simple feature alone. Any pertinent data stored on the Doctogram can easily be shared with the medical providers at a visit or remotely. I am sure others will find its many other simple to use features very useful. I highly recommend it.
