Frequently Asked Questions

Q: Does the Ola Esporte Smart Ring work without a smartphone?

A: The smart ring passively collects data (steps, heart rate, sleep) throughout the day and syncs to your smartphone via Bluetooth 5.3. You need the companion app on an Android 8.0+ or iOS 10.0+ device to view your data, start specific workout modes, or trigger SpO₂ readings. It does not support standalone calling, music, or a built-in display.

Q: How waterproof is the smart ring, and can I swim with it?

A: Yes! The ring carries an IP68 waterproof rating and 5ATM water resistance, meaning it can be submerged beyond shallow depths. It is safe to wear while showering, swimming in a pool, or at the beach.

Q: What sizes are available, and how do I find my correct ring size?

A: The ring is available in sizes #6 through #14, corresponding to inner diameters from 16.5mm to 23.0mm. To find your size, measure the inner diameter of a ring you already wear comfortably, or wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length in millimeters — then match it to the size chart above.

A: The 15mAh battery provides 3–5 days of use under dynamic conditions. Charging is done via the included magnetic charger. An optional charging case is also available. Avoid using high-voltage adapters to protect the battery.
