Why do you sometimes feel great in the morning and other times like you've hit a wall? With this ring, you'll understand. It measures the length and quality of your sleep and its individual phases. In the morning, it shows you your overall score and creates a detailed sleep profile.

Finally start doing THAT sport you've been putting off for so long. Niceboy ONE Ultra will accompany you in more than 150 activities. It will also measure your steps, calories, heart rate, and blood oxygenation. You'll see in black and white how you're improving your fitness.
