Frequently Asked Questions

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

A: The ring passively records heart rate, SpO₂, and activity data on its own, but you'll need the SmartHealth app (Android 8.0+ or iOS 10.0+) connected via Bluetooth 5.3 to view trends, start sport modes, and receive alerts. There is no standalone display or touch interface on the ring itself.

Q: What ring size should I choose?

A: The smart ring is available in sizes #6 through #14 (16.5mm – 23.0mm inner diameter). Measure the inside diameter of a ring that already fits your finger comfortably and match it 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.

Q: Is the smart ring waterproof?

A: Yes. The ring carries a 5ATM waterproof rating, meaning it can withstand water pressure equivalent to 50 metres depth — suitable for swimming, showering, and everyday water exposure.

Q: How do I charge the smart ring?

A: Two options are available: the included magnetic charging cable or an optional charging case (choose your preferred method at checkout). Avoid high-voltage chargers and always use the dedicated accessories for best results.

Q: Is the health data from the ring medically accurate?

A: The ring's static heart rate accuracy exceeds 98% in lab testing against a chest strap, and step-count accuracy exceeds 95%. However, this product is not a certified medical device — all readings are intended for personal wellness reference only. Please consult a healthcare professional for clinical guidance.
