Easy to use, looks good, works well
HeartStar seems very good so far. It allowed me to import my existing readings (with notes) from a CSV file I had in Dropbox. It has nice graphs. Its very simple to enter BP readings manually (it can talk to some Bluetooth-enabled monitors, but I dont have one; I was able to tell it I will always enter readings manually, so now it goes directly to the manual-entry screen when I tap the button to take a reading). It let me email myself a very nice PFF of my readings, it can also export them to a CSV, and it synced the data to the Apple Health app (when I enabled that feature). Overall very professional.
