"Quick temp checks, does the job"
It’s quick for checking temps and works fine overall. Every now and then I have to try again to get a reading, but it’s not a big deal.

"My Morning Routine Would Collapse Without It"
I started using this right after waking up, it’s been way easier than I expected. The first few days I was a little clumsy with it, but now it just fits into my morning like it was always meant to be there. At this point, if I skipped it, my whole day would probably feel completely off the rails...

"I feel way less worried than I..."
I feel way less worried than I did before. Each month I’m getting more comfortable and confident, and it’s been a big relief

"Delivery was slow and tracking was useless"
The shipping took way longer than what the site said. The tracking didn’t really tell me much either, it would just sit there with no updates, so I had no clue where the package was half the time. The product did show up in good shape eventually, but the whole delivery part was kind of a hassle and stressful.

"Umm, data sync has been good for me"
Umm, it syncs quickly and I haven’t had any issues with losing my data, so it’s been working fine for me.

"Still going strong after years"
I’ve had this tough little device for years and it still works like it did on day one. if the next one doesn’t hold up this well, I’d probably start looking at another brand, but so far I’ve got no complaints.

"Instructions were clear enough for me"
I thought the instructions were easy to follow. I’m not usually one to overcomplicate things, so I just went step by step and didn’t have any real issues getting through it

"Helped Me Feel More "In Tune""
This really helped me understand my body better. I feel more "in tune" with what’s going on and more aware of what I need day to day.

"Good info, but whoever runs this should add more studies"
I’ve been using Daysy for a bit now, and I do like that they actually explain the science instead of just throwing out huge claims. The cycle tracking makes sense to me, and the app has been easy to use. I did look through some of the studies they mention, and they seem decent, but I still wish there was more independent research to back it all up. Whoever runs this should really make that a bigger focus. Overall, it’s been a solid experience, just not perfect.

"At first, my partner wasn’t totally sold on..."
At first, my partner wasn’t totally sold on it, and I was a little worried we’d end up regretting the purchase or not getting our money’s worth. After using it for a bit, though, they got used to it and it turned out to be okay. Not amazing, but not something I feel like we lost out on either.

"I really like how clean and simple..."
I really like how clean and simple the daysy looks. It’s small enough to fit in my drawer or toss in my bag, so bringing it on trips isn’t a hassle at all. Forgetting it would be totally preventable since it’s so easy to pack. Overall, it’s a cute little device and super convenient...

"I’ve been using daysy for a few..."
I’ve been using daysy for a few months now, and I like how straightforward it is in the morning. The red and green days are easy to follow, which helps a lot.
It did take me a little while to remember to measure right after waking up. The app also feels a bit slow here and there.
Overall, I’m happy with it. It’s not perfect, but it makes tracking feel simpler for me.

"Pretty easy return and quick refund"
The return was easy and there wasn’t any annoying back and forth. My refund showed up a few days later, and support got back to me quick. it went smoother than I expected

"My cycles are really inconsistent, so..."
My cycles are really inconsistent, so I was worried daysy wouldn’t be useful for me. It’s been easy enough to use, and I do like that it adjusts instead of treating every month like it’s exactly the same. I’ll admit I was a bit disappointed that it took longer than I expected to get used to, and I didn’t feel totally confident right away. But overall, it has helped me feel less confused, so I’m glad I stuck with it.

"Good most of the time"
I’ve been using it for a few months now, and most days it works fine. The battery still holds up well, which I appreciate. Syncing can be a bit slow now and then, and it does make me wonder a little about the overall quality, but I still trust it enough for regular use

"Worth it for me"
I wasn’t totally sure about the price at first, it felt like a lot. But after using Daysy for a while now, it does feel worth it to me. It’s easy to use and I like that there aren’t any random monthly costs added on, so yeah... the value feels good.

"It’s fine, just not totally stress-free"
It’s been working for me so far, so that’s good, but I still find myself double-checking the dates all the time. Maybe that’s just me being cautious, but yeah, I wouldn’t say it feels completely relaxing to use.

"Took Me a Little While to Warm Up to It"
I had mixed feelings at first. The first week was kind of confusing, and I wasn’t totally sure I was going to stick with it. But once I got into the routine and figured out how everything worked, it started making a lot more sense. I do like it now, even if it’s not perfect.

"I’ve been using Daysy for a few months..."
I’ve been using Daysy for a few months now, and so far the temperature readings have been really consistent. I usually take it around the same time every morning, and it’s quick, simple, and easy to stick with. I also appreciate being able to see the pattern over time, because it makes the whole process feel more reliable. No issues on my end so far.
