The device has been invaluable in getting back into an exercise regime and having peace of mind after being diagnosed with a cardiac issue. This is a really great product. I would love to see some extra functions and alerts, and it would be great to be able to check on the current ECG that is being recorded during a workout. It would also be great to have a shortcut button in the app for an instant ECG.

The Frontier X2 is an excellent device – accurate, reliable, and packed with advanced features for heart and performance monitoring. It gives me confidence during training and long-distance runs. My only suggestion: please create a dedicated app for the Samsung Galaxy Watch Ultra. Having live data and coaching directly on the watch would make the Frontier X2 truly unbeatable. Highly recommended!

Excellent HR monitor, app missing health connect. For Android users, health connect is what the best health apps are connecting with. Every major activity tracker app and many other health apps support syncing with health connect. Please add this feature, so I can get the heart rate data imported to where I want.

Unfortunately customer service appears to be nonexistent at this point. I've sent 3 emails over the past couple of months about an extremely frustrating sync issue and have received no response. Whenever finishing a workout, the sync times out getting the workout summary, and it takes at least 10 minutes to reset everything to get sync working. I've purchased 3 of their straps and first reported this issue a few years ago. At this point many hours of my life have been wasted dealing with this!

The app has been bugging me lately. It keeps kicking me out and saying my user doesn't exist. The first time it did this, it caused my whole app to mess up. It doesn't let the actual ecg of your activity pop up till days later now, and you have to keep the device itself consistently on and running just to eventually get the app to register previous activities? Which is dumb. When it's processing to sync, it should automatically be syncing up for the ecg, not waiting till a week later.

Sandeep? Unable to connect the app until Sandeep approves it? Also, unable to make selections at key stages such as 'goals' and 'location services' where it either does not accept the selection or there is no option to select. Not a great start to owning a FF2 monitor!
