One ring for all your flows. Workflow, cashflow, and mindflow. It can do everything you need during the day. It monitors your rest, any activity, and your overall wellbeing. And wherever you are, you can pay just by holding your finger.

No monthly fees

Speaks your language

The app is available in Czech and can be switched to Slovak, English, and Polish.

Connects with iOS and Android

The app is available for iOS and Android and can be connected to Apple Health and Health Connect.

A smart ring brimming with health indicators

You'll know when to slow down and when to push yourself. Smart sensors in the ring read your body 24/7. Red, green, and infrared LEDs and a digital sensor in the core of the ring monitor your health, sleep, and sports performance. Advanced technologies measure a range of metrics – from sleep quality and stress levels to activity performance.

Finally, you'll understand what your body is telling you

Now you'll fully understand your body's language. Sensors on the ring accurately monitor your heart rate, blood oxygenation, temperature, and stress levels. You'll find the collected data neatly organized on your phone.

Monitors heart health

It measures heart rate variability (HRV) as well as your heart rate and blood oxygenation.

Alerts you to stress

Find out what stresses you during the day and when and how you recover best.

Measures temperature

An elevated temperature alerts you to increasing stress, impending illness, or menstruation.

Experience the best sleep of your life

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.

Overall assessment of sleep quality

Your sleep score shows you how well you rested. Are you going to go full speed ahead today, or take it easy?

It tracks individual phases

It knows when you are resting. It recognizes light, deep, and REM sleep, as well as the time when you are just tossing and turning.

It monitors your health even at night

You sleep, it monitors your temperature, blood oxygenation, and heart rate variability (HRV).

Measure your performance in 150+ sports and activities

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.

Calculates your activity score

How much are you moving today? Your score will tell you straight up: on a scale of 1 to 100.

Helps you meet your daily goals

Set your steps, calories, and distance. The ring will tell you if you're on track or need to step it up.

Detailed movement statistics

Exercise smartly. The overview shows you the measured distance, pace, and heart rate zones.

Pay without risk

You can see your payments and activity in the mobile app. You can connect your payment card to your phone via the Niceboy Pay app. It works for both Android and iOS. The ring pays for itself: no internet, no phone, contactless. Download the Niceboy ONE app for the ring's smart features. Activities, health statistics, sleep, personal goals – everything the ring measures and monitors is clearly displayed in one place. Both apps are available in Czech and Slovak.

Touch and beep

Pay contactless and completely securely Touch the terminal and beep. Paid! The smart payment ring pays contactless via NFC. We also replace payment card details with a unique token that does not carry any sensitive information. This gives you complete control over your money.

Encrypted payments

We encrypt every payment with a token that protects your data.

Works even when dead

You can pay with it literally anytime. Even when the ring's battery shows 0%.

Works offline

What's more, you can make payments without a cell phone or internet connection.

Lasts up to 7 days without charging

It can handle a week non-stop at full capacity. Then put it on the charging case and in 4 hours it's ready for action again. You can pay with it anytime – yes, even when it's completely discharged. 0% battery and payments still work! The only time you really can't make a transaction with it would be if your account balance is insufficient.

Ready for everyday life

Smart on the inside, tough on the outside. The ring can handle a full day's work with you. An hour at the gym, then work in the garden, afternoon shopping, and evening relaxation in the hot tub.

Waterproof 5ATM

You can wash dishes with it, swim in the pool, or even take a hot bath at home.

A hypoallergenic ring

Even if you have sensitive skin, you can wear 21st-century technological gadgets.

Durable and lightweight

Durable zirconia ceramic is not easily scratched.
