  • Much Better, but still miss a key feature of the original app Mar 15, 2021

    By 79sed615
    This is much improved- having specific sections to track key aspects of a cycle is helpful rather than just writing my own notes. Glad you brought back the partner feature with an app! Still very much miss the ability to log a period day on the app rather than having to input it on the device!!

    I've been using Daysy for about 4 years and couldn't recommend it more. Having a highly accurate and all-natural method of birth control is important to me. Custmer service is very quick to respond and help me with any concerns as well. Thanks for everything!

    This app is so much better than the last version! I have the Daysy with a cable and it was always very frustrating to connect. I rarely synced it with my phone since it would take multiple tries to sync. Now, I have no issues and it connects right away every time. I’ve always loved the Daysy but this improvement makes things soooo much better. Thank you for fixing those issues and making my life easier !!!

    Love my daysy and how it helps me know my body well. It's helped my husband and I naturally prevent pregnancy and conceive when trying. I had the older version of daysy break unexpectedly and the team replaced it with the updated version for free! Also love the newer app so much more. Very user friendly and less glitchy.

    The app is awesome and easy to use! It would be better if the app connected and shared its data with the Apple Health app

    I liked the old app layout better than this "new and improved" one. With the old one I could easily see the whole month at a glance and there'd conveniently be little red dots on the days I should expect my period. That was my main reason for getting this, so I can know when to expect them as they come on fast, heavy and undetected. Please update to reflect this loss of information!!

    I’ve had my daysy since 2017 and have used it off and on. The app interface on the old version always frustrated me. It felt outdated. This new app is so much cleaner, easier to use, and has been working great for me! So much so that I decided to purchase the newer Daysy 2.0. Thank you Valley Electronics! Keep the app updated and fresh and you’ll have a Daysy user for life!
  • It’s okay. May 4, 2021

    By shana3513
    I like that it gives me information but I don’t like the small colored dots under the calendar day, they are very hard to see. I prefer the old app for this reason. Also in the chart section I wish it could be enlarged and could just would say 96 degrees, 97 degrees etc instead of 95.9, 96.8, 97.7. To me it takes more time and focus. I prefer the old chart abs calendar view. But I do like the other updates.

    I love my daysy, but I really prefer the layout of the old app. I like the monthly view, fluctuating chart, and the last page that had average lows and highs. It was alot more user friendly for me. I will keep using the original version for as long as I can. 5 stars for the daysy and customer care. 3 for the new app.
  • NFP/FAM made easy!! Dec 14, 2020

    Absolutely love this app! It syncs fast and has lots of new features. Makes it so much easier for me to track everything in just one app! I also love the fact that there’s a partner app so that my husband can follow along whenever he wants! Highly recommend!

  • Not very impressed Mar 10, 2021

    By lac2021
    This app works faster than the previous one but the tracking options are very similar. I was hopping to track details such as spotting (bleeding outside of the regular period time), ovulation test results, etc. There are so many options in the market that track everything in one place and pair with BTM devices. I feel frustrated for having bought A device as expensive as daysy and not getting everything I need. Why can’t you save your period without syncing with the thermometer? This is crazy, I couldn’t sync my device at the moment I entered my period details and now I can’t input the actual day my period began. Very disappointed.

    With the new app I suddently have synch issues and have to try 3 to 5 times everyday until it works. Never had an issue with the old app. And I really miss the "predicted period"-drops in the calendar which were great. Some stats are not/wrongly displayed: my average low and high temperature are both displayed with 32 degrees now, both wrong. Some stats is says "calculating", wigh the old app there was a clear numer there (for eg. "Missed measurements" would be 0, but it says "calculating").

    The data loads incredibly slowly. It takes about a minute before loading finishes. I feel a lot of functionality has been hidden with more taps needed to be done to access it. I don't mind the interface too much though.

    I have used the Daysy thermometer and the old app for years. I'm going back to the old one, as it is hard to see the monthly view and statistics. I find this new app very hard to navigate.
  • It’s okay Jan 18, 2021

    By Buth8nfjbt
    This app is alright, I wish it asked more detailed questions about bloating, sex drive, pms symptoms etc. Is there anyway to have the daysy automatically sink with the app? It’s a bit annoying to do it manually
  • App Keeps Crashing Feb 19, 2021

    By vermills
    Whenever I try syncing my data the app crashes. I tried deleting the app and reinstalling and it still won’t work.
  • App won’t open Dec 13, 2020

    Seems to still be some knock to fix.. app will not stay open for more than 5 seconds.

    Daysy has changed my life! I can't reccomend using daysy more. I currently use her for birth control, but, I am looking forward to using daysy when trying to conceive as well. Daysy has helped my partner take ownership of birth control as well. He will ask "so, what color are we today" and he knows if I am fertile or not. We have relied on daysy for almost 3 years now. PLUS I love the new app. I had the pleasure of participating in beta testing.
  • Intuitive, easy to use, insightful! Dec 9, 2020

    By Daisygatsby25
    DaysyDay is smooth and fun to use. You can track so much! Cervical fluid, period type, and I like to add notes on what supplements I took and my mood changes. The historical data breakdowns are amazing for a cycle nerd like me! And syncing is a breeze. So happy!

    Missing the statistics page with the average temperatures, ovulation fluctuation etc. Which is too bad because it was very informative. The calender view which only shows one week at a time isn't as comfortable, I prefer the monthly view. I like that there are more options for recording notes that include explanations and also that notifications were added. Overall the app isn't as easy on the eyes as the daysyview.
  • A company that listens Dec 19, 2020

    By Naturalmomma
    As a long time Daysy user, it’s nice to see the improvements in the new app that are definitely from the suggestions made by the users and I look forward to what comes next.
