Cons
Con Oversensitive pedometer overestimates your step count
The fitness tracker's step counter often counts movement unrelated to walking or running as steps. It ends up reporting more movement than has actually happened.
Con Hard to get the tapping right to active LED display
The double tap to activate the LED display lights must be the appropriate pressure and timing in order for it to work correctly. This can be frustrating to some users.
Con Too unreliable for the cost
The Vivofit 3 has multiple serious issues impacting its reliability which means you're taking a gamble by purchasing it. At $80, you can get trackers with much better build qualities and a similar set of features.
Con Software that detects different activity often doesn't work
The "Move IQ" software in the tracker, which is supposed to detect different types of exercise, often doesn't work. Either it will track everything as walking, or will not start tracking them all.
Con It's easy to lose the watch because of the weak clasp
The clasp frequently comes undone during physical activity because of its poor design. If you aren't constantly paying attention to it or add re-enforcement to the clip, it would be easy to lose the tracker.
Con Syncs with a limited number of devices
Con Not for people with small wrists
The tracker is available in two sizes, regular or extra large. The regular band is too long for people with below average sized wrists.
