I purchased to replace my Sense which went DOA while swimming recently. The Sense 2 is different than the previous model. It does not track snoring (a feature I used with the old watch). At this time I am using the Fitbit Premium app. Because Google now owns Fitbit the app will be phased out next year. I will be trying the Google fit app soon. The new watch is different with new displays etc. I will review the product again on the Fitbit app then on Google. I will use it swimming often.Verified purchase: YesCondition: New

6 day battery! Vibrating alarm!
Love it! Charge lasts 6 days! Can’t beat that! Easy to set up & use. Great fitness & sleep tracker. My favorite feature is the alarm though. It gently vibrates me awake versus startling me with noise.Verified purchase: YesCondition: New
