Ultrahuman Ring is the best smart rings I’ve tried: it’s super light, comfortable to wear all day and night, and the build quality feels really premium. The sleep and recovery tracking are excellent, giving clear insights on HRV, sleep stages, and readiness scores that actually match how I feel. The app is clean and easy to use, turning complex biometrics into simple, actionable advice. If you’re serious about optimizing your health and performance, this ring is absolutely worth it.

Was quite happy with this sizing set as it allowed me to choose the right size of the ring without guessing. Perfect option

I’ve been using the Ultrahuman Ring for some time now, and it has really helped me understand my sleep patterns better. The insights around sleep stages, recovery, and readiness are very useful and easy to follow. The app is clean, intuitive, and gives actionable guidance rather than just numbers. Battery life is solid, and the ring is comfortable enough to wear all day and night. Overall, a great product for anyone serious about improving sleep, health, and recovery.

The ring turns of after one day and the support is not helping me. Now the ring turns not on anymore and still no help. Support is telling me to update the ring wich is empty and so not able for an update. Better pay more money for a better brand with good customer aupport

I love this ring! It’s comfortable, and provides detailed and acurate information! What I love most about it is that it is subscription free, and it has the lowest EMF exposure and literally cancels it out once the phone is in airplane mode or Bluetooth is switched off, yet it still collates the data and syncs when the device settings are switched back on. The only thing I’d like to see changed is the fact that you have to put the ring back on the charger to take off of airplane mode, this feels unnecessary. Especially when you have to do this daily, if you prefer to monitor sleep while reducing emf exposure. The only thing I’d change is the fact that you have to put it on the charging deck to take it off airplane mode. There may be a good reason for this, but it does seem unnecessary and is a pain to do each day.

Perfect!! Amazingly created and packed! Really high end!!

Amazing insight very useful ring. Better then competitors

لا ادري ما فايدته

手首にウェアラブルバンドを使ってたのですが、寝てる時につけているのが嫌だったので、スマートリングにしました、軽くて付け心地もよく、今のところは気にいってます。 スマートリングのブランドとしては、海外ではそれなりに人気があるようですね。 アプリの表示項目は多くて、よくある活動量以外に回復や睡眠は細かいデータが表示されます。 睡眠改善が目的で購入したのですが、朝に振り返ると、前日の活動量や飲酒、寝た時間の影響など良かったり悪かった気付きがあります。 またPowerplugsといわれる追加機能で、睡眠に関連するようなカフェイン摂取の推奨時間帯がみれたり、日光浴の時間記録、スマホのスクリーンタイムの可視化、体内時計のリズムなどいろいろな機能があり、まだ上手く使いこなせてないですが、睡眠の質向上に活かせたらなと思ってます。 バッテリーは3日前後といった感じです、追加機能をオンにしてたり、アプリもよく見るほうだと思うので、仕事中に座ってるときに2、3日に1回充電してます。 リングの中には安いのもいろいろあるようですが、データが数値やグラフで細かく表示され、追加機能もありお値段するだけの高機能なリングだなと思ってます。月額料金がかからないのもいいですね。 睡眠改善と、回復も意識して使い続けたいなと思います。

Goed maar na passen nutteloos

llevo usándolo 3 meses y es parte de mi rutina diaria. La batería dura mucho y las métricas son parecidas a law del Apple Watch así que ya no dependo del reloj tanto. Y estéticamente es guapisimo

La pila dura 2 giorni non 6 le info non sono esatte volevo sostituire L Apple Watch ma non sono riuscito uso di nuovo L Apple Watch

secondo me il miglior ring... purtroppo se lo prendete colorato la vernice si toglie facilmente, però per il resto non ha abbonamenti nè altro di periodico ed è molto sottile
