Love it. My polar watch battery went out so I decided to try the under armour band since it wa just sitting in my closet. It is pretty accurate and does a great job at tracking my calories burned. My iwatch isn't dependable when it comes to working out since it constantly loses my heart rate and says my heart rate is 60 when it's really 170, and doesn't accurately count calories burned. Overall, great monitor and app!

Finally Working ‼️

Well with some tech support UA39 finally working. I was very disappointed with this when it wasn't working mainly because it was such a good dependable band. Even with new update, tech support worked and got it going!!! I have been very pleased with UA support ‼️


I love this app. I have been using it for over 2 years. The next update I would love to see is making it compatible with "Myfitnesspal". I like how Under Armour Record is compatible with various different apps.
