Heart Rate Monitor:

This feature is important because it tracks your heart rate throughout the day and during activity, which gives you a general idea of how well your heart is functioning.

This feature is available in all Fitbit pieces except Ace, Flex 2, and Alta. The Alta HR, Charge 2, Versa, and Ionic use PurePulse technology to give you uncut, automatic heart rate monitoring that is wrist-based.

They also have Cardio Fitness Level that gives you a snapshot of your cardiovascular fitness. Added to these, the Versa and Ionic monitor the amount of oxygen in your blood using a Sp02 sensor.

Automatic Sport Recognition:

The Alta, Alta HR, Charge 2, and Ionic include tracking of multi-sport exercising.

They can recognize when you’re running, hiking, playing sports (like basketball or football), or cycling.

They can also recognize aerobic activities like Zumba, kickboxing or dancing. They log all of these activities with the log of workouts to give you an extensive exercise summary.


The Flex 2, Ace, Alta, Alta HR, Charge 2, Versa, and Ionic contain a motor for vibration to grab your attention when an alarm you set goes off.


The Fitbit Ionic has eight sensors and is the only one in the line to include built-in GPS with no need for a smartphone to be linked. This feature allows users to track distance, pace and elevation climbed, as well as review routes and split times.

The Charge 2 and Versa can be connected to your smartphone if you want to use GPS services.

Water Resistance:

The Flex 2, Versa, and Ionic trackers are sanctioned as waterproof (down to 50M) and have some swimming monitoring features like the number of lengths and distance swam. The Zip is merely splashproof, while the Alta, Alta HR, and Charge 2 are water resistant to 1 ATM.

Floors Climbed:

More effort is exerted into floor climbing, so it’s a nice addition to keep track of that and the Charge 2, Versa, and Ionic have an altimeter that lets you do just that.

Sleep tracking:

All of the Fitbits except the Zip track your sleep to measure the time you spend sleeping and check the quality of your sleep, which has a major impact on your general health.

The Alta HR, Charge 2, Versa, and Iconic also have sleep stages measurements to give you a general clue on how much you spend in Light, Deep or REM sleep. The Charge 2, Versa, and Ionic feature Relax Guided Breathing sessions that aid you when you’re trying to calm your body.

This helps reduce stress, anxiety, and blood pressure.

How To Choose The Right Fitbit for Men?

Battery life:

This feature is very important if you consider keeping track of charging your devices a burden. The best Fitbit to let you avoid this hassle is the Zip with a battery life that lasts up to 4-6 months.

The Alta HR lasts up to 7 days. The Flex 2, Ace, Alta, Charge 2 last up to 5 days; as well as the Ionic but the duration might be reduced depending on GPS use). The Versa has the smallest battery life that lasts up to 4 days.

Finally, the choice you make is highly dependent on the feature you’re seeking after the most.
