Usa DaysyReviews of usa.daysy.me

My experience has been good so far. The app does what it says it will do. The reason for 4 stars instead of 5 is a glitch and preference. 1.) The glitch - sometimes it takes me a few attempts before my phone will sink to the app. I'm not sure if that's an app issue, or a hardware issue. I know one customer service person suggested I apply pressure to the phone end of the cord when I sink it. That's a bit annoying, though not the end of the world. 2.) The preference - I wish I could input specific data that I could then see show up on line graph. As it is now, any data I input, I have to do to that specific day to find out what the data actually is. Confession - if y'all could do something similar to Kindara, that would be ideal. I'm sorry, I'm sure that's annoying to read. But I like to engage with my data, rather than just trust the green/yellow/red lights on my Daysy (though I appreciate those).

I love my Daysy! I think it's function is designed perfectly. My only complaint is I wish it was a bit more durable. For a nearly $400 product, having the peace of mind that the dainty thermometer won't snap in half when I travel would save me a lot of stress!

Good Customer Service, Didn't Love The Product

Fantastic device! Makes life so much easier. My ONLY issue is with the app. If I forget to input my period I can't enter it at all after a few days. This is seriously annoying and I really wish they would fix it so I can edit/input past menstruation within the app/ in the Daysy. Because of this it has predicted me being pregnant because I entered only one day bleeding which I guess it disregarded as not a real period? For some reason I thought it would realize I was having my period since I inputted my period but this wasn't the case. Otherwise it's literally the best thing ever, I just wish they would fix the app!

I really do like my Daysy, which I have been using to prevent pregnancy for about a year. I will say however that it has been “tricked” before by outside factors, such as traveling. I had a delayed period because my inner body clock was out of whack after a long trip, and because my ovulation was also delayed I had higher than usual temps and no period during the week I was supposed to get my period. The Daysy gave me green lights when I was actually in my most fertile time, thinking that window had already passed, and then thought I was pregnant when I didn’t get a period. So, I could have become pregnant had I had unprotected sex during that time, and the pregnancy lights for the weeks that followed were very unsettling. I was taking pregnancy tests every day until I finally got my period and everything was back to normal. So, I was never pregnant and it gave me a week of green lights at a point they should have been red. If I wasn’t paying attention I easily could have become pregnant in my first year of using this product, which I purchase to prevent pregnancy, and I can’t say that it’s accuracy has been 99% for me, as it was advertised. But overall, when conditions are normal it works great for body awareness and knowing when to be extra careful. I’m also super happy to be off hormonal birth control! Just know there’s a learning curve and to be really careful until you fully understand your cycle, not just when the Daysy thinks it understands your cycle. You are still smarter than the machine!

It’s very conservative. It only relies on basal temperature to determine fertility. Based on other signs (cervical mucus observation and wet/dry feelings) I believe you could have more green days. It gives me red/yellows when I personally know I’m no longer fertile.

Great product! Just wish the app was better.

I really love the Daysy. It is so amazing and really helps me track and predict my cycle. The only thing that I wish was different is the ability to change/edit a day that's already passed. It allows up to 3 days to edit.
