Love this app!
Easily breaks
This is device is very expensive and yet the end of the temperature gage broke off so now this is useless to me as it won’t read a temp. I only had this a little over a year.

Enttäuscht
Ich hätte mir mehr Möglichkeiten gewünscht um meinen Körper zu verstehen. Aber die App ist wirklich nur auf Fruchtbar oder Unfruchtbar ausgelegt. Doch ich erhoffte mir ein Zyklustagebuch welches mir Hilft meinen Körper und Psyche besser zu verstehen und allfällige Muster, wie schlechtes Selbstwertgefühl immer 6 Tage vor der Periode, Kopfschmerzen während Eisprung etc., hervorhebt. Ich würde mir solche App updates sehr wünschen. Durch die Beschreibung des Geräts und der Herstellerfamilie ging ich nämlich davon aus dass dies so integriert ist. Jetzt muss ich alles selbst in den Notizen eintragen und selbst auswerten - also braucht es noch ein weiteres App. Messer ist jedoch gut und tut was er soll - aber für den Preis hätte ich einfach eine bessere App erwartet.
weird UI spacing with new phone
great app but got a new phone and the menu bar at the bottom is really close to the home screen bar thing which makes the buttons a lil hard to press
Excellent
I have used Daysy for almost a decade. It is top-notch, and customer service is always speedy and very helpful. The Bluetooth feature to sync Daysy to the app is quick and easy, but I also love that you don’t have to rely on the app if you chose not to, as the device itself gives your fertility status for the day. I definitely recommend Daysy and also the Daysy Day app.
Really not great for cycle tracking
I’ve had this product for over a year now, and when you’re on top of it great. For real life and when you fall off and restart it’s really annoying as it doesn’t let you back date log periods to map out your cycle so far. Honestly really not happy with the product in general, it’s slow to read, app isn’t flexible for logging, and it’s pretty pricey for what it is.
Guter Start, kleine Wünsche
Die Daysy hat trotz der Lernphase schon viel bei mir erkannt, bin sehr zufrieden. Bei den Spalten zum eintragen würde ich mir noch wünschen: -Muttermund: stand, offen oder zu -Symptome: Mittelschmerz, spannende Brüste ect. -Stimmung: sehr gut, müde, schnell reizbar Sonst freue ich mich, übers weitere gegenseitige kennenlernen mit der Daysy 😉
Hardly has the bare minimum
Unfortunately the app has fewer features than any period tracking app. It would be amazing if it clearly outlined your pre ovulatory temp range, gave you the average and compared with your post ovulatory to see that shift and make sure your temp change is high enough to confirm ovulation/ tell the state of your hormonal health. Instead, you have to calculate the avg yourself and do the math. For the ammount of $ you pay, the app should offer a bit more.
Störungen und Unflexibilität
Momentan wird der letzte Zyklus einfach nicht mehr angezeigt, der Mai ist grau hinterlegt und es kann nichts eingetragen werden. Zudem werden oft die Server gewartet und währenddessen ist eine Pflege der eigenen Daten nicht möglich. Wenn man dann noch die drei Tage „Karenzzeit“ verpasst hat, hat man Pech gehabt und der Zyklus mit Periode ist nicht korrekt hinterlegt. Dann kann ich auch wieder einen Papierkalender führen und mit eigenem Basalthermometer messen. Ich bin seit 2021 Nutzerin und war eigentlich immer zufrieden bis jetzt.
Love this app and period tracker
One word for this product. Amazing! Been using it for almost 6 years.
Not for perimenopause
It’s been nearly 6 months and still has no clue about my cycle. I know myself better than this device. Has me fertile over 15 days. Prediction for period has not been correct. Don’t waste your money
Good but can be great!
I wished the app would provide more information on what is going on in that day in particular. As I transition from red to yellow and green, it would be great if there was a little AI or smart box that gave you tips and info for that day and upcoming so woman can prepare mentally and emotionally. But over all it does the job! I’ve been using it for about 9 months now and my fiancé and I love it!! Truly recommend the product!!!
Seit Monaten tägliche Wartungen, Datenübertragung fehlerhaft
Der Server wird bald täglich für Stunden gewartet und das schon seit Monaten. Die Temperatur kann oft nicht übertragen werden.
Best tracker so far but does not take correct temp
This is the best tracker for a real menstruation and ovulation tracking. It’s the only one that actually considers the rest of the female population that does not run on precisely 27 days. Now the issue is the temperature reading is always lower than what my other four thermometers read. So if you’re trying to track your actual body temperature this may not be accurate, but it does give you a consistent temperatures even if it is low. And make sure that you are taking your temperature correctly because you’re not allowed to take it more than once. So if you don’t put it under your tongue correctly, you will have a bad reading and it will mess up their predictions
Best fertility tool!
I’ve been using Daysy for a few months & its been so easy to track my cycles. I Know more about my body now. Sometimes I miss quite a few measuring days and that gets a little annoying but the device it’s self and the app works great in my opinion.
Dislike
Honestly, for as much as it was this app is not super easy to use and sometimes does not log things even thought I logged it. Wish I would have returned it
add LH test feature please!
i just got the app and so far it works great. but if there was a way to add the LH test strip tracker that would be SO helpful. that way i could track all 3 symptoms in one place (temperature, discharge, and LH peak) instead of using multiple apps.
Kalender funktioniert nicht…
Leider funktioniert seit Monaten der Kalender nicht richtig. Zum Beispiel ist gerade April und ich kann den Kalender nur bis Februar anschauen, obwohl die App aktuell und Daysy gesynced ist. :-(
Leider nicht NFP tauglich
Ich mag das Konzept und die App total, störend und verunsichernd ist für mich jedoch, dass ich die restlichen Merkmale (Zervixschleim, Muttermund) nicht nach NFP Regeln tracken kann und die Messung rein auf Temperatur basiert, man aber aufgrund der fehlenden Eintragemöglichkeit nicht selbst nach nfp nachrechnen kann, ohne eine zweite App zur Kontrolle zu nutzen. Ergänzungen bzw Anpassungen wären sehr wünschenswert.
Love Love Love!
This app and device are great, simple and I LOVE how minimalist it is. I hate other apps that want to track moods, pains, etc. and constantly ask, how are you feeling today. This simple, clean, direct app/device is perfect and I highly recommend.
App needs updated
App is not user friendly.
review
need to be able to edit period info for more than 3 days in the past.
Tw fraglich
Sperrung von “nachträglichen” Bearbeitungen Null Hilfreich … macht am Ende die Statistik mehr als falsch.
Better ones out there
It’s a bit annoying how you can’t manually edit things like your period that are too long in the past (e.g. when you go on holiday and leave your Daysy at home) which then means you have to wait until your next periods for the chart to have the correct colours and recognise where you are in your cycle. You also can’t log positive pregnancy test results that the app recognises or log the end of a pregnancy. I think it would be a lot more helpful (especially when you start using the app) if you could log the first day of your period even if it’s in the past. That way it wouldn’t take so long for the app to give you predictions. The battery life is pretty good though. I’ve been using Daysy for half a year now and haven’t charged it since.
Dpo
Can u add on app days pass ovulation to help us keep track
Horrible - would give a 0 star if possible
I’ve bought multiple (3) of these because they have easily broken… and not once did the company help out or hear/replace crappy product. The tips are WAY too fragile and break off within days of use. It takes so long to actually take your temperature as well. I will never purchase or refer this product to anyone.
Love it- but improvements could be made
Overall I love the Daysy and the app! The 2 changes I wish I would see are: having the temperature graph show smaller increments, and being able to sync the daysy with other apps. The graph showing 0.1 degree increments (F) are helpful, if not necessary for those of us using daysy as a tool when avoiding pregnancy with FAM. Being able to easily sync the daysy to automatically put temps in other apps (such as read your body) would be very helpful, as many of us use multiple apps to track things. This is something temp drop is doing and a reason why I may make the switch.
Unabhängige Funktionen fehlen
Man kann die Mens nicht ohne Daysy eintragen. Das finde ich echt schlecht. Zumal man sie immer mal vergessen kann. Auch nachtragen klappt nicht.
Insgesamt ok
An sich eine schön übersichtliche App. Toll, dass die Notiz für den Zervixschleim dazu gekommen ist! Die offiziellen Angaben wie bei NFP wären mir aber noch lieber. Zu Daysy selbst: Die Eisprung-Berechnung ist leider fast immer falsch. Durch Zervixschleim & NFP-Regeln kann ich recht genau bestimmen, wann mein Eisprung ist und dieser ist immer früher als „Daysy“ ihn angibt. Auch bestätigt wurde mir dies durch meine Gynäkologin, die mir sagte die Berechnung kann nicht passen und im Ultraschall hat sich dies ebenfalls bestätigt. Wäre schön, wenn der Algorithmus dahingehend nochmal überarbeitet wird.
I love this app however !!!
I love this app so much however I wish there was a way to change it from Celsius to Fahrenheit 😃
Awful
When I log my info it disappears right away This is not user friendly
LOVE!!! One request…
So good!! Please add a spot along with mucus etc to add LH reading high/low/peak! I use in conjunction with a clearblue (as I think many women do!) and this would be so helpful to log it all in one place!!!!
Basic
I love my Daysy thermometer, but the app is basic at best. You can only log your period, sex, cervical fluid and notes. Right now I’m using this app and using the FLO app to track the rest of my symptoms, moods etc. It would be nice in future updates to get more options to track so I don’t have to use multiple apps to track everything.
Option mehr Daten einzufügen fehlt
Es wäre ganz cool wen man auch Ovulationstest-Ergebnisse eintragen könnte…
I love daysy
Daysy just makes my live more easy about cycle tracking! As a IOS user, I would like to recommend you guys if we could add daysy application to IOS health application too! Just something for you to think about ❤️
Not great
Having a lot of issues syncing
Good but more connections please
The Daysy is a great device for accurately tracking your cycle, hormones and fertility. The accompanying iPhone app works well but it could be improved by allowing it to connect to and write data to other health trackers. Particularly Apple Health and Fitbit. My Fitbit app has the capacity to record and track daily core temperature but I don’t want to have to enter it manually each day.
Doesn’t make sense
I’ve been using since Oct 2023 it’s Jan 2024 and info is off. It gives me a green light to have sex when I’m in my period and no sex when I’m off my period. I like the physical design and the concept of syncing my temps. But the product does not work as intended for me.
Past reviews are correct
Reading years old reviews with responses that these improvements are coming… and they are not here unless I’m missing something. I agree that a $300 device should have a much more robust tracking system. Like others have noted, there are many free period apps that track cervical fluid, mood, cravings, cramps, etc. I also hate that you can’t edit your period more than 3 days after the fact. Often times i don’t get around to syncing my device to the app and miss tracking day 1. Surely there are some similar devices with apps that are much more robust now? But having paid so much for this one I’m kind of stuck with it.
Daysy & DaysyDay have changed my life 🤍
I love this app & the device that goes with it! The staff are so helpful & the technology has changed my life. I am so happy this app exists.
Terrible app
For as expensive as this tool is, the app should be better. I should be able to manually enter period information if I’ve forgotten or lapsed past the three day window.
Could be better if connected to Apple Health
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
Not very impressed
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.
It’s okay.
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.
Gave me the confidence to get off of BC
After 10 years on the BCP, I learned about the sympothermal method of birth control and was extremely intrigued. Always wanting to get off of BC, but not willing to take the risk of pregnancy, I felt trapped. I watched a ton of utube videos, read articles, and considered doing this several ways. I decided to buy the Daysy and read TCOYF, as well as The Period Repair Manual. I also bought a cheap thermometer to compare and I use the free Kindara App as well. It may seem like overkill, but I highly recommend Daysy because without it, I would not have had the confidence to do this on my own. It does read more accurately than the cheap thermometer, and instead of having to look at it first thing and record it... I can simply set down my thermometer and get the readings later. I think there is something psychological about having a pretty thermometer that makes sweet sounds and reassures you that your charting correctly. I don’t have the money to have a personal instructor, but I do have a thermometer that confirms where I am at in my cycle. I am still doing things extremely conservatively, as I did even while on BC. It takes a while for Daysy to learn you and there is a learning curve if your doing TCOYF, but I think without Daysy I would not have stuck with this and in my opinion it’s 100% worth the price. Babies are much more expensive, and so is the peace of mind that I’m not destroying my body with HBC. Love my Daysy. Highly recommend. Customer service is great. It’s a machine so a glitch here and there doesn’t both me- they are always making improvements to it too which is amazing. The work involved it much more satisfying and better than having to go to the pharmacy every month to buy hormones, and remember to feed my body hormones every day.
Lagging
App has been lagging and now letting me click on different days or scroll to different months. This has been a problem for months now
Much Better, but still miss a key feature of the original app
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!!
It’s okay
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
Progress
I feel like the app has made progress but mine crashes all the time and currently I can’t even sync my daysy without it crashing...
