## Description

Introducing the Oura Ring 4 — the next generation smart ring that has evolved. With your health first, the Oura Ring 4 has a new design made from all titanium, and "smart sensing" that adapts to you beyond just measures. Quietly and comfortably monitor over 30 biometrics including sleep, recovery, activity, heart health, stress, and women's health. With up to 8 days of battery life, you'll forget you have it on.

Review: 運動記録用として購入しました。(5ヶ月継続中) 体調の検知は正確で、運動量の計測は概ね信じれる内容でまとまっており、大きな不具合ないので満足してます。 ストレス検知についてだけは、ゲームをしていてもリラックスして動画を見ていてもすぐにストレス判定されがちなので自分の心に従って無視してます。 サイジングキットでサイズ合わせ数日試着した上で購入してますが、本体購入後、浮腫んでいたのが解消されると数日で指が細くなったのかスカスカに落ちそうになったり、現在は装着する指を変えたり運動しすぎないように気をつけてますが 公式サイト的には人差し指に装着を推奨してますが、痩せやすい方は中指でサイズ合わせをお勧めします。
Review: 事前にサイズキットを購入して１，２日候補となる指でつけて生活することはマストです。 Ouraリングそのものはデータが好きな人間にとって最高のツールです。 結構厚みもありますが、日常生活で邪魔に感じることはほとんどなく日常の一部になっています。

事前にサイズキットを購入して１，２日候補となる指でつけて生活することはマストです。 Ouraリングそのものはデータが好きな人間にとって最高のツールです。 結構厚みもありますが、日常生活で邪魔に感じることはほとんどなく日常の一部になっています。

買って確かめて良かったです。普通の指輪のサイズとは異なるため、確認してからOura Ringを買うのがお薦め。
