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 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.

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.

I got the ozi sleep tracker mainly because I wanted to monitor my child’s sleep without asking him to wear a watch. I use apple watch myself, but I knew my child probably wouldn’t be comfortable sleeping with it. He was also curious to see his own sleep data, so this tracker made a lot more sense for us. So far, it has worked really well for what we need. I especially like the real-time monitoring because it helps me tell if he is actually in bed sleeping or if he got out of bed. I don’t have to keep checking on him all the time. Another big plus is there is no subscription fee. A lot of sleep tracking products needs monthly plan, so I really appreciate this one doesn’t have it. The app is clean and pretty easy to understand. The data is shown clearly, and I didn’t have much trouble figuring it out. The only complaint is that the tracker can be a bit sensitive sometimes. If my child moves around near the edge of the bed, the app sometimes show he is in bed. It corrects itself pretty quick though but hope this can be improved in future updates. Overall, I’m very happy with it. For anyone who doesn’t want to wear a sleep tracker, this has been the best solution I found so far.

Very easy to set up and surprisingly accurate. I really like that I don’t have to wear a watch to track my sleep. The reports are clear and helpful, and the app is simple to use. Highly recommend! I also want to buy one for my parents so that I could track their sleep everyday without worries.

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 like this sleep tracker for a number of reasons. The price is reasonable for all the information it provides. There are no ongoing monthly subscription fees after the initial purchase. The unit is easy to setup. Simply spread it out on your bed just underneath your mattress sheet and plug it in. Download the app and go through the easy to follow setup instructions. I found the flat unit to be virtually undetectable under the mattress cover. Use the app to set your firm wake-up time and any optional wake-up window. Your phone will sound a gentle alarm within that window of time if it discerns you are naturally waking up from a sleep cycle. See my photos to see the options that the app allows you to monitor. Many of the screens are also interactive. Press your finger on them and slide to highlight the areas on the screen to see at precisely what time your heart rate increased or decreased. While some may question the accuracy of the unit reading your sleeping information, I believe that the unit is useful to determine the relative changes in your sleep patterns. You can use this to make beneficial changes by getting to bed earlier, not using your phone prior to going to sleep, not eating before bed, etc. I believe anyone purchasing this would realize significant benefits in changing their sleep habits, and then being able to monitor the benefits of those positive changes.
Everything you need for better sleep insights, no strings attached.
