It WAS great, but now stinks. Like others have said, when the app works, it's really cool and I love how it tracks everything. No problems when I first had it in 2019. Now, their Software is very glitchy, the connection is always slow or lost, and most recently my app loses sound within a couple of minutes pulling it up. I no longer trust it to alert me for anything. The worse is they don't even seem to care. They have done nothing to improve themselves in the last few years. 😞
