Frequently Asked Questions

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

A: The ring does collect basic activity data (steps, heart rate readings) in the background, but most features — including viewing SpO₂, sleep analysis, sport modes, and alerts — require a Bluetooth connection to the SmartHealth app on your Android 8.0+ or iOS 10.0+ smartphone.

Q: How do I find my correct smart ring size?

A: Measure the inner diameter of a ring that fits your desired finger in millimeters. Match that measurement to our size chart: #6 = 16.5 mm up to #14 = 23.0 mm. When between sizes, we recommend sizing up for all-day wearing comfort.

Q: Is the smart ring waterproof enough for swimming?

A: Yes! The ring carries a 5ATM waterproof rating, meaning it is suitable for swimming, showering, and sweaty workouts. Avoid high-pressure water jets or deep-water diving beyond the rated depth.

Q: How long does the battery last and how do I charge it?

A: The 15 mAh battery is optimized for the ring's low-power sensors. Battery life varies by usage (continuous heart rate monitoring uses more power). Charge using the included magnetic charging cable or the optional charging compartment case — simply attach and charge.
