DaysyFertility Tracker – Natural Hormone-Free Ovulation Monitor & Fertility Awareness Device – Smart BBT Thermometer with App for Cycle Tracking, Conception, or Pregnancy Planning – FSA/HSA Eligible

I honestly DONT know how anyone can have an issue with this device. Those who do either didn’t read the Manual so the learning curve must seem steep or miss temperature days which is the whole point of how this device predicts. I’ve only had this device for two months and already it is MIND BLOWING on how accurate it is. I do manual FAM charting to cross reference and to be safe but each time it matches DAYSY’s predictions.Please go on the DAYSY website BEFORE buying to determine if you are compatible with this device. It helps more to have a consistent cycle. READ THE MANUAL!!! It helps to understand the button faster, its colors, and rules on exceptions. Watch YouTube videos on DAYSY reviews and instructions to understand the device.I will say that the app was annoying on the day I set up the DAYSY(syncing issues). So If you are not a very patient person or if you try to do it on the go, I can see how you can assume that it’s not working. But since set up( which took an hour or so) it has run smoothly. I have forgotten to put in my period and gone back the day after to do so. I’ve also put my period on the wrong day accidentally and corrected it very easily. Correct things as soon as possible. It’s not a magical stick. You need to give a bit of attention and consistency to get the most out of it.

Me costó mucho decidir en comprarme Daysy por su elevado coste.Había leído quejas por la tardanza del dispositivo en darte más días verdes (que son los días seguidos para mantener relaciones sin embarazo). En mi caso que soy irregular y solo llevo un ciclo, ya me ha detectado para este mes 11 días verdes.En Europa es considerado como un dispositivo médico. Tiene una fiabilidad del 99.4%, una pasada, teniendo en cuenta que no hay hormonas que dañen tu cuerpo.A día de hoy, estoy completamente segura de que hice bien en invertir ese dinero. La tranquilidad que te da, el tener tu cuerpo libre de hormonas si no quieres un embarazo, o al contrario, saber cuándo es el momento en que estás ovulando para buscar un embarazo. Incluso es capaz de detectar un embarazo por la temperatura.Claro que tarda aprender el patrón de temperaturas de tu ciclo, ya que cada mujer es distinta. Vivimos en una sociedad en la queremos todo para ayer, y hay cosas que merecen la pena tirar de paciencia, el porcentaje de fiabilidad es altísimo, hay que tener en cuenta que los años fértiles de una mujer, es un tiempo prolongado en nuestra vida, y merece la pena unos meses de testeo, a cambio de la fiabilidad que ofrece, tanto si buscas embarazo, como si no.Cada mes que pase te va a ir poniendo más días verdes.Yo solo puedo recomendarlo, lo único que me apena, es no haberlo descubierto hace años...

We used the Baby comp for almost 12 years, which was great, but limited. Daysy makes data available to you by using the ios or android app, and there is also an option for making data available for husbands. This device can help you plan your family in a sustainable and healthy way.

This has to be my biggest Amazon purchase regret and I wish I could return it after 4 months of trying. It is so hard to use, hard to remember how to use, the app sucks, and this technology is not nearly as smart as it leads you to believe. You can’t track your period start days unless you remembered to take your temperature that morning and you can’t go back and update information from over 3 previous days so if you forgot to take it your temperature you’re screwed. You have to manually sync the Daysy to the app and the app to the Daysy- this is fairly straightforward but not something you’d expect from a $300 device. The app feels outdated and pales in comparison to competing apps like Flo. I sincerely do not know how this has 5 star reviews on every platform. If it were $20, it’s totally worth the money. Maybeeee $100. But $300 is ridiculous for how cheap it feels, how outdated it is, and how complicated it is. I seriously doubt this was even made by women for women.

I loved the idea of the daysy when the first model came out. At the time it was not in my price range . Fast forward 2021 hormonal bc just isn’t for me so I decided to try it out . It’s nice how this is super easy to do and syncs flawlessly to my iPhone . I’ve had zero issues with the syncing . Color coding very easy to understand

There are tutorials on the app on how to use this. It makes it fool proof. I definitely suggest reading about fertility awareness before using this item for such.

This a great alternative if you trying to avoid hormonal birth control. I have been using it over a month and learning about how it works before I get married this fall. I am still learning about this device ,but after awhile you get the hang of it. It also has helped me to learn more about my body and the way it works more so than I knew before. The videos for Daysy on the website is very helpful and highly suggest it. Also the people on the website are awesome at answering questions/helping.
