What does it do?

AURA Strap 2 measures your body composition and hydration level on your Apple Watch.

Does it work with my Apple Watch?

Supports Apple Watch Series 3 to Series 9, including Ultra 2 and SE. It connects with 38/40/41 and 42/44/45/49 mm Watches. Choose the size to fit your Watch.

How can body composition tracking help me?

A series of day-by-day measurements shows the trends as your body composition changes. It makes your workouts more efficient, because you can understand (by the numbers) what exercises are definitely good or bad for you.

Does it measure hydration?

AURA Strap 2 measures how much water you have in your body with the help of bioimpedance analysis.

Does AURA Strap 2 fit my wrist?

Each device comes with 4 sets of Infinite loops.

The set for 38/40/41mm Apple Watches includes XS, S, M, and L loop sizes and fits 130–200mm wrists.

The set for 42/44/45mm Apple Watches includes M, L, XL, and XXL loop sizes and fits 140–220mm wrists.

You can pick the size and tightness according to your preferences!

Can I share AURA Strap 2 with a friend or family member?

With the "Guest" feature, you can let your friend or family member take a measurement. It won't affect your progress data.

Is it waterproof?

AURA Strap is water resistant. The device will not be affected by high moisture or immersion in water up to 50 cm / 20 inches. But the device may suffer from direct exposure to high-pressure water stream. We do not recommend swimming or using the device in the shower.

How are AURA Strap 2’s electrodes made?

The electrodes on each side of the device are made using medical stainless steel (contains nickel).

How long does it work on a single charge?

AURA Strap 2 works for up to 6 months using a standard, replaceable round coin battery (CR1632). Simply change spent batteries with the included pick, and it's ready to use.

Is it safe to use AURA Strap 2 with a pacemaker?

No, we don't recommend using the device with a pacemaker.

Can the AURA Strap 2 detect medical conditions or illnesses?

No, the AURA Strap 2 is not designed to detect or treat any medical conditions or illnesses.

How does Strap 2 connect with Apple Watch? Is it secure?

Strap 2 uses a BLE 4.2+ interface to transfer measurement data. Data transferred between devices is encrypted. The reliability of Bluetooth reduces the number of unsuccessful measurements by 99.99% and allows users to take measurements in any environment.
