Finding the smallest fitness tracker band to fit your arm or hand comfortably can be quite overwhelming once you discover just how many different brands and designs are available in stores and online today.
Fitness trackers have come a long way, and since first being introduced back in 2009 by Fitbit, many versions and designs have evolved into highly technical monitoring devices.
I have found not only the smallest smart bands but even smaller smart rings that will effectively track your heart rate, count your steps, monitor calorie expenditure, measure your quality of sleep, and even GPS tracking enabled.

Here are some of the smallest activity trackers I could find that is extremely slim and lightweight but also designed to comfortably fit all wrists.
If you are willing to take the leap into even newer technology, and something even smaller than a fitness tracker band, then make sure to also check out our fitness tracker ring.
Do Smaller Fitness Tracker Bands Work as well as Others?
From what I’ve seen, even the smallest fitness tracker bands including the rings work just as good at tracking than any other tracker design.
Fitness tracker watches may have a few more display features due to the bigger sized monitors, but the bands nonetheless still hold up equally as well when it comes to tracking features.
We have found smaller fitness bands to be much more functional and practical to use when exercising. The fitness watches and larger bands can be less practical as they are heavier and bulkier and thus tend to move and slim around more than the smaller bands.
We have tried to give you a wider choice of fitness band designs to provide you more options when searching for a new band. All of the following bands are slim fit and lightweight designs. You will find both fitness bands with and without displays, all are waterproof, and we have even included a fitness tracker ring to our list.
How well do Smart Rings Work Compared to Fitness Tracker Bands?
Fitness tracker rings are actually quite effective at monitoring and reading various activities and uploading that information to your smart device via Bluetooth technology.
Smart rings can monitor your heart rate, count calories burned, register steps and distance, and even keep track of your sleeping patterns.
These rings are very durable and extremely small. Thus, making them the most inconspicuous and smallest fitness tracker on the market.
The fitness ring we have included in this review is the Motiv Ring which is waterproof, is extremely durable, and made from ultra-light titanium.
The only drawback to a ring versus a band is that by not having a display monitor it is only for reading and gathering information and sending it to your phone App.
