Frequently Asked Questions

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

A: The ring records data passively on its own, but most features — including viewing heart rate trends, SpO₂ readings, sleep analysis, and sport modes — require the SmartHealth app on a Bluetooth-connected Android 8.0+ or iOS 10.0+ smartphone. It does not support standalone calling or music.

Q: How do I know which ring size to order?

A: Measure the inner diameter of a ring that already fits, or wrap a strip of paper around your finger and measure it flat. Match that measurement to the size chart: #6 = 16.5mm, #7 = 17.4mm, #8 = 18.2mm, #9 = 19.0mm, #10 = 19.9mm, #11 = 20.7mm, #12 = 21.5mm, #13 = 22.3mm, #14 = 23.0mm. When in doubt, size up for comfort.

Q: Is the smart ring safe to wear while swimming or showering?

A: Yes! The ring carries a 5ATM waterproof rating, making it suitable for swimming, showering, and sweaty workouts. Avoid prolonged exposure to high-pressure water jets or hot springs.

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

A: The built-in 15mAh battery typically lasts several days depending on usage and monitoring frequency. Charge using the included magnetic cable or the optional charging case. Always use a standard low-voltage USB adapter for best results.
