★★★★★ Best sleep tracker and is soft and thin

Reviewed in the United States on June 5, 2026

Best sleep tracker I had so far. Initially I worried that I'd feel the tracker under the sheet, but it is very soft and thin and to whoever is asking the same quesiton, you can feel it with your hand but if you sleep on it, you don't feel it at all. Really good work to the team on app, cool ui and mostly importantly, easy to understand. anyone who don't want a watch to sleep with should get this.

I don't always like wearing my smart watch to bed for sleep tracking, so I wanted to give this a try. This tracker is really easy to set up. It pairs with my phone and the app is user-friendly. In fact, the app is better than I expected. I like that it keeps track of my heart rate along with my sleep tracking. I also love that it tracks how long it takes me to get to sleep. I often feel like it takes too long but the app helps me see that it doesn't always. This sleep tracker goes between the sheet and mattress and needs to be set at chest level. I was worried it would be uncomfortable but I haven't noticed it when sleeping. It's more comfortable than I anticipated. This stays plugged in at night. I like that I don't have to think about recharging it. There are a few bugs with this. I don't always think it is accurate. Sometimes the readings seem off. The cost is a little high for those who already have a sleep tracking device. However, it's nice not to have to wear a device to bed. Overall, this is functional and does what I was looking for.

★★★★★ I can see how my partner's day is going to look like and when she’s going to be moody

I recommend this sleep tracking device! I am in a long distance relationship, I know that my partner sleep bad and I couldn’t do anything about it so it triggered me and I bought it for her (she thought about getting a sleep tracker but it’s impossible to sleep wearing something on). We LOVED it… it shows great data, and I love being able to see when she sleeps, and how well she does. I can also see how her day is going to look like and when she’s going to be moody. Overall good experience with a good sleep tracker that we have a great use for us that we didn’t expect it initially.

★★★★★ Comfortable, easy to use and accurate

I am an RN and honestly exhausted… I am working night shifts my sleep is destroyed, and I need good sleep to function. I wanted to track my sleep I have an apple watch but hate wearing it while sleeping (already struggling with sleep I don’t want to make it harder wearing something on my wrist) and I need to charge it so it doesn’t work for me. I got this sleep tracker because it was non contact and I recommend it, easy to use, accurate and comfortable (I don’t feel it at all). I love the fact they allowed me to set myself as a day-time sleeper, so the data is accurate and easy to understand.

Frequently Asked Questions

General: Does OZI require a subscription?

No — never. OZI is a one-time purchase. App access, every feature, and lifetime updates are all included. There are no monthly fees, so you own your data and your device from day one.

For Parents: Can OZI support more than one child?

Yes. OZI supports multiple family members through Household Mode. You can set up a profile for each child and manage everyone’s sleep from one dashboard. Each sleeper you want to track needs their own OZI device.

Shared Bed: Can OZI track two people in the same bed?

Each OZI device is designed to track one sleeper at a time. If two people share a bed and both want accurate data, we recommend one device per person, placed on each side of the bed.

Technical: How thick can my mattress be?

OZI works under your sheet on top of a mattress or a topper up to about 4 inches (10 cm) thick. It’s compatible with memory foam, hybrid, innerspring, and latex mattresses.

Privacy: Does OZI use a camera or microphone?

No. OZI has no camera and no microphone. It uses a contact-free sensor placed under your sheet to detect movement, breathing, and heart rate — so there’s no video, no audio, and no surveillance of any kind.

For Adults: Can I use OZI if I do not want to wear a watch or ring?

Absolutely — that’s exactly what OZI is for. Nothing is worn. Just slide the sensor under your sheet and sleep normally. No ring, no wristband, no charging a device.

For Caregivers: Can I check sleep patterns for someone I care about?

Yes. With OZI Remote Care, you can securely check a loved one’s sleep from your phone — ideal for parents monitoring children or caregivers looking after elderly family members.

Alerts: Can OZI notify me when someone leaves bed?

Yes. OZI can send an optional bed-exit alert the moment someone gets out of bed, so you can respond quickly without staying on edge all night. Alerts are designed to stay quiet unless something meaningful happens.
