Finally understand my sleep

I don't usually write reviews but I had to. I've been feeling tired for ages despite getting 7-8 hours every night. Within the first week I could see that I wasn't getting REM sleep. This led me to adjust my wind-down routine and within a fortnight the difference was noticeable. Worth every cent.

So glad the sleep data has been useful Sarah!

No brainer at this price

I wasn't sure at first but now I'm very happy that I went with the QuantumRing over Oura. This does everything I need. Very happy.

Much better than I expected for the price

I was a bit hesitant buying an Australian brand I hadn't heard of but the specs looked solid and the price was right. Two months in and I'm really impressed. The accuracy seems good, the battery is great, and the Google Fit integration works without any fuss. Would recommend without hesitation.

Blood oxygen tracking gave me a heads up

My SpO2 readings were consistently a bit lower than expected which prompted me to mention it to my GP. Turned out I had some minor sleep apnoea that hadn't been diagnosed. Obviously the ring isn't a medical device but it flagged something worth checking out. Really glad I had the data.

Really glad the data was useful Gary. It's always worth getting these things checked out. Hope you're feeling better!

Tracks my shift work sleep patterns brilliantly

As a nurse doing rotating shifts my sleep is all over the place. This ring has helped me understand the impact of night shifts on my recovery and which days I need to take it easier. The data is consistent and the ring keeps tracking regardless of when I sleep. Really helpful for someone with an irregular schedule.

Shift workers are one of the groups who get the most out of sleep tracking. Glad it's helping Melissa!

Shipping was super fast

Ordered Thursday evening, arrived Monday morning in Melbourne. Wasn't expecting that. Ring was well packaged and came with everything needed to get started. Set up took about 10 minutes. Happy with the whole experience from purchase to using it.

Waterproof — wore it surfing no worries

Took it surfing no worries. Works perfectly. Heart rate data after sessions is interesting to look at too. Really solid build quality for the price. My mate ended up buying one after seeing mine.

Fat burn tracking is a feature I didn't know I needed

Was browsing the specs and noticed the fat burn duration. It's actually really useful. Combined with the calorie data it's given me a completely different way to think about exercise.

Good ring but took a day to get used to

Took about a day to get used to wearing a ring 24/7. Data has been really useful, especially the sleep breakdown. Would have liked a slightly more detailed onboarding to explain all the metrics but once I figured it out everything made sense.

Thanks Ryan!

Noticed my resting heart rate drop over 6 weeks

Started using this when I began a new exercise program. Over 6 weeks I could actually track my resting heart rate come down from 72bpm to 61bpm. Having that visible progress tracked automatically is really motivating. The ring just sits there and records everything without me having to do anything.

That's a fantastic result Nina. Keep it up!

Brett Sullivan
Great value, does what it says

No frills, just works. Tracks sleep, heart rate, steps, blood oxygen. Syncs to Google Fit. Battery lasts ages. At this price point it's a no brainer compared to spending hundreds on a brand name ring that does the same thing.

Apple Health sync works perfectly

iPhone user here — the Apple Health integration works seamlessly. All my ring data shows up in the Health app automatically. I use it alongside my Renpho scales and get a really complete picture of my health every day. Shipping was fast too, arrived in 3 days.

Best health purchase I've made in years

I bought this on a bit of a whim and it's turned out to be one of the best things I've done for my health. Understanding my sleep stages has helped me fix a problem I didn't even know I had. I was barely hitting any deep sleep and now I know why and how to fix it. Brilliant little device.

HRV tracking changed how I train

I'm a runner and I've started using HRV to guide my training load. When my HRV is low I take it easy or rest. When it's high I push hard. My recovery has improved noticeably and I haven't had an overtraining issue since. The ring makes it easy to check every morning without thinking about it.

Solid ring, app could be improved

The hardware is great and the data it collects is accurate from what I can tell comparing it against other devices. The app is functional but could be a bit more polished. That said for the price point I'm not complaining, the core tracking is spot on and it syncs to Apple Health without any issues.

Thanks for the honest feedback Marcus! Exciting app improvements are on the roadmap.

Pairs brilliantly with my Withings scales

Set this up with my Withings scales and Google Fit and it's the best health setup I've had. I can see my total calorie burn for the day adjusted by my actual body weight. Makes it so much easier to know how much to eat. The ring handles the activity side perfectly.

Comfortable enough to forget you're wearing it

I've tried fitness watches before and always end up taking them off because they're annoying to sleep in. The ring is completely different — after day two I genuinely forgot it was there. Sleep data is far more accurate as a result because I'm actually wearing it all night.

That's exactly why we love the ring form factor Chloe! Glad it's working well for you.

Great for tracking stress levels

I work in a high-pressure job and wanted something to help me understand my stress patterns. The HRV data from this ring combined with the stress tracking has been eye-opening. I can see exactly which days take the most out of me and plan recovery accordingly. Really useful tool.

So glad I didn't buy the Oura

Really useful for understanding stress

Work in a high-pressure job and wanted something to track recovery. The HRV data has been eye-opening - I can see exactly which days take the most out of me. Game changer for how I manage my workload.

Forget you're even wearing it

Tried fitness watches before and always took them off at night. The ring is completely different - after day two I forgot it was there. Sleep data is actually accurate now because I'm wearing it all night.

Changed how I train

Using HRV to guide my training load now. When it's low I rest, when it's high I push. Recovery has improved a lot and no overtraining issues since I started. The ring just does it automatically every morning.

Watched my resting HR drop over 6 weeks

Started wearing this when I began a new training program. Resting heart rate went from 72 to 61bpm over 6 weeks - visible in the data the whole way. Really motivating to see the progress tracked automatically.

That's a fantastic result Nina - real cardiovascular improvement showing up in the data!
