Frequently Asked Questions

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

A: The ring passively records heart rate, SpO₂, sleep stages, and steps on its own, but you need the SmartHealth app (Android 8.0+ or iOS 10.0+) connected via Bluetooth 5.3 to view data, start specific sport modes, or enable alerts. It does not support standalone calling or music.

Q: What is the waterproof rating, and can I swim with it?

A: The smart ring carries a 5ATM waterproof rating, making it safe for swimming, showering, and exposure to rain. Avoid high-pressure water jets or deep-water diving beyond the rated limit.

Q: How do I choose the right ring size?

A: Wrap a flexible tape measure or a strip of paper around the base of your intended finger and measure the circumference in millimeters. Match that measurement to the closest size: #6 (16.5 mm), #7 (17.4 mm), #8 (18.2 mm), #9 (19.0 mm), #10 (19.9 mm), #11 (20.7 mm), #12 (21.5 mm), #13 (22.3 mm), or #14 (23.0 mm).

Q: How accurate is the heart rate monitoring on this smart ring?

A: Static heart rate accuracy exceeds 98% based on lab testing against a reference chest strap. Step tracking accuracy is greater than 95%, powered by a proprietary self-developed algorithm. Results may vary slightly during high-intensity movement.

Q: What charging options are available?

A: The ring supports two charging methods: an included magnetic charging cable or an optional charging case (choose one at checkout). Always use a standard low-voltage USB adapter — avoid high-voltage chargers to protect the 15 mAh battery.
