I'm a big fan of garmin fitness trackers. I've tried all different brands and the Garmin Vivosmart HR is probably the best. I just ordered the HR+ so I am a fan.....My first suggestion is giving users the option to customize their own app experience. The dark theme is ok but I should have the option of changing it to a light/white background theme. Being able to make that change at my convenience would be very user friendly! Look at the 'new' Fitbit app. It's excellent. Garmin should look at that as a good example to build upon. Garmin has the better tracker. Fitbit has the better app experience.....As well the swimming metric needs to be fixed. Since the Vivosmart HR and HR+ are swim friendly the laps should register. The HR+ has built in gps. This should be updated on the band/app. Also water consumption is important. The Fitbit app lets you document your water conaumption daily on the app with a chart of your weekly consumption. Garmin needs to add this to their app as well. Thanks for listening!
