For Father's Day, Fitbit has discounted its most popular fitness trackers, including the Alta, Charge 2 and the Flex 2. These are also its newest fitness trackers. The Fitbit Alta is discounted to just $99, making it one of the best fitness trackers under $100. The Charge 2 is just $129, and the Flex 2 is $59. All of which are great prices (between $20 and $40 off).
The Alta is the more elegant of the bunch. It's a pretty thin fitness tracker, but it does have a display that will show you all of your stats for the day, including the time and some notifications. The Charge 2 does the same thing, although it has a slightly larger display. The Charge 2's big feature that the Alta does not have is the heart rate sensor. Now the Alta HR does have one, but that isn't actually discounted (still a good one to pick up though). The Flex 2 is a popular one because of its price point. It also does not have a heart rate monitor, but it does have waterproofing. And it can actually track your swimming, which is something the others can't do.
