Why Simply Smart Recommends the Oura Ring 4
"Oura Ring 4 review: The best smart ring gets even better with more accurate sleep tracking" — TechRadar
At Simply Smart, we crowned the Oura Ring 4 #1 Smart Ring 2025 because it delivers premium titanium build, 30+ biometrics, and advanced recovery insights for unbeatable value. Oura – the pioneer that started the smart ring revolution in 2013 and remains the undisputed king on Gen 4 – proves you get the best experience.
At Simply Smart, we test 500+ gadgets every year, including countless industry leading smart rings like Samsung Smart Ring (Most popular alternative), RingConn Gen 2 (Most popular alternative #2), ULTRAHUMAN AIR (Most Popular Alternative #3), Movano, Evie, Canexis, Jackomm and more! But only the Oura Ring 4 (made by one of the original pioneers of the smart ring industry), and Amazfit Helio ring (matching our PAI and Amazfit watch lineup) are the only ones that made our list for 2025 – tied for the best overall. We may add RingConn in 2026 once their health tracking accuracy improves (perhaps with Gen 3), especially for sleep apnea focus. Oura Ring 4 is the undisputed king as the pioneer that's been in the smart ring game much longer than Amazfit, Samsung, and all competitors, focusing solely on perfecting rings since day one.
