This is a good app for those of us who regularly keep up with our heart rate. I use the adage ‘What gets measured, gets managed.’ Therefore, when you regularly check your pulse through out the day, you begin to manage it. You know that you need to exercise it just as you do the rest of the body. The only downside that I see in this app, is that when I want to do a check either during or just after a brisk walk, I have to wait for a minute or two for ads. While this is happening, I am losing vital info as my heart rate is slowing without being measured thus skewing my actual results.
