Thank You and Great update!

Thank you for creating this app! I can now use my Qardio Arm after the Qardio app disappeared. The latest update now is even better to sync to Apple Health!

Thank You!!

I cannot thank Paul enough for creating this app. Not only has it prevented my BP cuff from becoming e-waste, this app works better than the manufacturer’s did! And it’s free! A triple gift!
