Make sure your Motiv Ring fits just right with the Motiv Smart Ring Sizing Set. Designed for use before purchasing a Motiv Ring, this set ensures you choose the best size for your finger. Offering the ideal blend of fit, form, and function, Motiv Ring is one of the most compact fitness trackers. Combining numerous features in one device, Motiv Ring tracks calories burned, heart rate, steps, resting heart rate and sleep. Additionally, it uses your heart rate data and movement to focus on the most important metrics. Featuring a stylish and comfortable design, Motiv Ring is easy to wear throughout the day and night. Since Motiv Rings come in slightly different sizes than traditional rings, the sizing set makes sure you get the right one. It’s best to wear the rings for at least 24 hours to determine whether it’s a good fit for you.
