Like the app

Overall, the app is pretty decent. Only thing that would make it better is to add the HR to all of the backgrounds, including the gallery ones. Part of why I chose this tracker was the HR monitor but I cannot customize the background to my photo and keep the HR in view. If this were to be updated, I’d give it 5 stars
