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

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.

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.
