Smart BP & Heart Rate Monitor

This app had good reviews, but for me it is lacking: I do not see a way to change units (lb vs kg or inch vs cm). I was primarily looking for a way to log and graph my blood pressure. The logging is okay, but the graphing is poor - if I log multiple blood pressures per day (such as a morning and an evening) the monthly and daily graph only shows one reading. On the daily graph I do not see a way to look at previous days. When scrolling in the daily, weekly, and monthly graphs to right the graph numbers (vertical axis) scroll off the left side so that you can’t see them. Both the blood oxygen and the blood pressure will record pulse rate, but they do not show pulse data on the graph. The blood oxygen has a place to add pulse rate, but does not show it anywhere after saving. It seems that the BMI is not calculating correctly. The app shows 29.4 while any other BMI calculator that I try shows over 40. Additionally, the BMI is not editable after entering - the results still show, but any changes to data have to start over. There is no graph for BMI or way to record BMI over time. Overall a very disappointing app. I will not be renewing.
