We strongly encourage that you refer to traditional ring sizes or take measurements at a jewelry store nearby to find your perfect fit.

Step 1 - Select a finger for your Smalth Ring.

• For the most accurate results, wear your Smalth Ring on your index finger. The middle and ring fingers will also work.

Step 2 - Measure with a tape measure or refer to your traditional ring size.

Step 3 - Confirm your perfect size by comparing to the SMALTH Standard Size Chart for Inner Diameter and Circumference below.

It will always remain free with the purchase of an Smalth Ring. The only cost is the one time fee of the ring itself.

The Smalth Ring app for iPhone will be available on the App Store for devices running iOS 11 or later. The Smalth Ring app for Android will be available on Google Play for devices running Android 6 or later.

Launch your Smalth Ring application.

The app will ask you to give it permission to access your Bluetooth and localization and then launch the pairing process. You will no longer have to perform the pairing process in the future.

Please note that the ring can be paired to one device at a time but an account can be paired to several rings. Your data is stored on your personal and dedicated account and only you will have access to your data. If you have the same Smalth account on several phones, you will be able to see your data on these several phones but without being able to synchronize your ring's data on the different phones. Your ring can only sync to one phone at a time.

It’s so simple that you have nothing to do yourself.

There is no on/off button on the ring, it knows when you are wearing it or not and goes into standby by itself if you don't wear it.

All you have to do is pair the ring to your Smalth Ring app and the ring will start recording data.

Yes, the Smalth Ring is water resistant.

It's suitable for light water exposure like rain, washing your hands or showering. Do not put the ring under water for prolonged time (bath, sea, hammam).

It is not recommended to use the ring when carrying weight. Damage may occur to the ring.

It is recommended to wear a special outer-shell for sports as it will scratch faster.

Like regular jewelry, Smalth Ring can scratch if worn while lifting weights or gripping bars, or when scraping against metal, ceramics or stone. Apart from carrying weight, you can do sports with your ring.

It is not recommended to wear the ring during extreme high (superior than 60°C) and low temperature (inferior than -20°C) for more than 30 minutes.

Use the included magnetic cable to charge via any USB socket, or simply place the ring in the included charging case.

Simply place the magnetic pins that are located on the flat part of your Smalth Ring onto the magnetic pins of the charger.

The pins of the charger will be in contact with those of your ring so that it can be charged.

A LED on the charger turns on to notify you of when the ring charges.

The charger turns off when your ring is fully charged.

It is currently not possible to synchronize Smalth Ring with other external applications, and will be added through a future app update.

The Smalth Ring is compatible with most mobile devices that run iOS 11 or later, or Android 6 or later.

The ring first collects the body metrics it needs thanks to its biosensors (green, infrared & red optical pulse sensor and 3-axis accelerometer). The ring contains a built-in processor that will process the data and send the data by Bluetooth to the Smalth mobile app & cloud for analysis.

The Smalth analysis engine uses machine learning to better understand your habits and offer a personal experience with personalized recommendations to improve your lifestyle.

When your heart beats, your capillaries expand, and contract based on blood volume changes. The optical heart rate sensor (PPG) in your Smalth Ring flashes its LEDs rapidly on the arteries of your finger’s palm side to detect blood volume changes. Your device calculates the number of times your heart beats per minute (BPM), which is your heart rate.

SMALTH tracks your sleep thanks to the correlation of the data collected by the PPG sensor, and the motion sensor. The biometrics of your body evolve during your sleep and your biometrics are in very specific states at each stage of your sleep.

That’s how the ring monitors whether or not you are sleeping and in what sleep stage you are in. SMALTH tracks many other sleep factors to let you understand your sleep and improve it in the long run.

Yes, Smalth Ring tracks heart rate during exercise and many other activities. 

Standby time is up to 30 days.

But it depends for daily use.

• Non-continuous monitoring provides optimal battery life and will collect cardiac indicators at a lower frequency with a battery life of approximately 7 days.
• when continuous monitoring is turned on, cardiac indicators will be collected at a higher frequency and battery life will be reduced to 2.5 days.

You can set this in the Smalth Ring App.

For the very first use, you will have to create an account on the app. Your SMALTH RING will be registered to this account once it is paired. A profile will be created, and all your related data will be stored on an encrypted dedicated and personal account. That way, if you lose your ring, you’ll still be able to have access to your data and continue with another one, right where you left off.
