Ratings and Reviews

Advertising is NOT okay


The new app is great! Except that it now throws animated banner ads in my face. I'm giving them the use of my money for interest, and paying them for services. There is no excuse for shoving banner ads into the experience.

Good but…


…the associated Applewatch app has stopped working. Will no longer sync with the iPhone app.

Crashes constantly
