I can't get the app to monitor heart rate or a few other things it's supposed to do (Android).The watch itself is beautiful, well built, looks and feels very expensive, from a historic brand. I absolutely love it.But all the smart features happen on the app, which I've tried for weeks and weeks, and just find lacking. Even if all the features worked, it has half the number of features as my $40 generic smart watch.I would recommend this watch as a normal sports watch. If you want a smart watch, there are plenty of less inexpensive options that do more.
