### 5/5 — improved my sleep quality

*2024-05-25*

I've been using Frenz for a month now, and I've seen a significant improvement in my sleep quality. I fall asleep faster, stay asleep longer, and wake up feeling more refreshed

### 5/5 — perfect for side sleepers

*2024-05-24*

I sleep on my side, and the Frenz band is surprisingly comfortable. It stays in place all night and helps me fall asleep faster. The app is user-friendly, and the sleep tracking is very detailed

### 5/5 — Good sleep wearable to have in the house

*2024-05-24*

I was concerned it may not fit my head size at first. However, it was no issue at all. It's comfortable and stays securely in place all night long. I now smoothly fall asleep, and have less sleep disturbances in the night. The charts provided in the app are giving me valuable insights into my sleep patterns and where I can improve. It took me 5 days to get used to wearing something while sleeping though. It is worth it overall! Highly recommended.

### 5/5 — Helps with my partner’s snoring

*2024-05-23*

My partner snores, which often wakes me up. Frenz has helped me stay asleep despite the noise. The headband is comfortable, and the back-to-sleep feature is very effective. I love the app UIUX - super easy to use.

### 5/5 — A good choice for business owner

*2024-05-09*

Frenz has helped me achieve a deeper, more restorative sleep. It’s a good choice for business owner like me who sometimes just need a quick fix for our disturbed travel times.

### 5/5 — Couldn’t imagine my bedtime routine without it

*2024-05-07*

The personalized approach of FRENZ is what sets it apart. Love how it tailors the experience to my specific needs.

### 5/5 — Great experience from the very first night

*2024-05-06*

I’ve always wanted to improve my sleep quality so I’ve tested out a variety of sleep trackers over the years, ranging from the old-fashioned journaling method to wrist-worn wearables. While they have their perks of continuous data trend, they also come with many limitations. Wrist trackers mainly measure things like arm movements and heart rate variability, but I’ve notice the inconsistencies between their data and my own behaviour. I even went extra miles by wearing both Oura and Garmin simultaneously for camparison (yeah I’m dedicated), and found that their reports often differentiated the most for my deep sleep duration and REM sleep duration. Then I also tried EEG trackers but none of them offered the real-time intervention methods like Frenz. Althought I’m still skeptical about their 89% accuracy compared to PSG in the sleep lab, this is the most accurate gadget I have found on the market with my sleep behaviour. I have noticed after a few days my deep sleep duration is slightly increasing with their deep sleep boosting feature. I do feel better over each day and still keep my sleep journal for my own experiment purpose. I would recomend everyone who want to purchase this band to read more about CBT-i audio techniques and how it works, so the slaudio voice can have better impact on your brain. From my own experience of listening to Calm and Headspace over the years, Frenz’s sleep audio content actually has better effect on me.

### 5/5 — Frenz has exceeded my expectations in every way

*2024-05-02*

Falling asleep faster and enjoying better sleep quality overall

### 5/5 — Impressive data

*2024-04-26*

Sleeplab data now gets into consumer space, and I can now biohack with a new level of accuracy

I’ve heen realy impressed with the realtime display of my brainwaves in EEG EOG EMG. For those who don’t really know why these signals are that important, it’s a huge assurance for me to test out these real time data as I test the accuracy by roling my eyes or moving my face muscles. It’s like something out of a sci-fi movie. As a
Scientist myself, naving these transparent data showcased makes me trust ther algorithms much beter. As for my sleep experience, having precise knowledge of my brain reaction alows AI to customize content to optimized just for me, which seems pretty straightforward.

I’ve only been using it for about six days, and I can’t even remember the music I listen to before falling asleep anymore. My average time to fall asieep has dropped to just 12 minutes. One feature I’m a huge fan of is the smart alarm function which can make waking up feel more natural
