The Ola Esporte Smart Ring is compatible with Android 8.0 and above, as well as iOS 12.0 and above. Simply download the companion app, pair via Bluetooth 5.4, and you're ready to go.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I wear the smart ring while washing my hands or in the rain?\u003c\/h4\u003e\n\u003cp\u003eA: The ring carries an IP68 \/ 5ATM waterproof rating, making it suitable for everyday splashes, hand washing, and light rain. However, it is not designed for swimming, hot showers, baths, or saunas — extended submersion is not recommended.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I choose the right ring size?\u003c\/h4\u003e\n\u003cp\u003eA: We recommend measuring the circumference of your finger with a soft tape measure or a strip of paper before ordering. The ring is available in sizes 6 through 12. If you are between sizes, select the larger size for the most comfortable fit, especially for the index finger where the ring performs best.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long does the battery last and how do I charge it?\u003c\/h4\u003e\n\u003cp\u003eA: Battery life varies based on feature usage, but the 13–15 mAh battery is designed for all-day and overnight wear. Charging via the included magnetic charging box takes approximately 1–2 hours for a full charge.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is gesture control and how does it work?\u003c\/h4\u003e\n\u003cp\u003eA: Gesture sensing allows you to use simple hand movements to control compatible actions on your smartphone — such as scrolling through videos or triggering the camera remotely for hands-free photos. This feature works through the ring's built-in acceleration sensor (DA267) in combination with the companion app.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does the smart ring work with both Android and iPhone?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
