Find All Your Fertile Days with Daysy and Lady-Comp
When it comes to getting pregnant, timing is everything. There are only a handful of fertile days each cycle when conception is possible. Daysy and Lady-Comp identify exactly when those days fall, including a prediction of your ovulation day, so you and your partner have the information you need to plan a pregnancy with confidence.
How Daysy and Lady-Comp Can Help You Conceive
One study found that 81% of couples who track their fertility and time intercourse on fertile days will conceive within 6 months 1.
Because conception is only possible within a short fertile window each cycle, trying without fertility tracking can lead to frustration and unnecessary stress. Daysy and Lady-Comp, used alongside the DaysyDay companion app, make it easy to know exactly when you're in your fertile window.
No OPKs, no pee strips, no complicated calculations, and no guessing. In around a minute each morning, Daysy and Lady-Comp tell you when the time is right to conceive. Take the complexity out of pregnancy planning and focus on the joy ahead.
No need to count days, keep records, or do any mental calculations. Daysy and Lady-Comp handle all of that for you. The simple colour-coded light system makes it easy for you and your partner to know when to try.
Daysy and Lady-Comp are backed by more than 30 years of research and a unique algorithm built on data from 5 million menstrual cycles, combined with your own individual data. Simply measure your basal body temperature under your tongue each morning and confirm your menstruation days.
Daysy and Lady-Comp then calculate your fertile days and predict your ovulation day.
Track Your Fertility to Conceive Faster
Research shows that the likelihood of conception in any given cycle, when intercourse occurs one or more times on fertile days, is 27.7%. Couples who timed intercourse close to ovulation had significantly better outcomes, with 98% conceiving within 12 months. Timing within a few days of ovulation is essential.
In our own survey of Daysy users, 63% reported conceiving in the first cycle they tried. A full 89% conceived within three months of using Daysy.
Daysy and Lady-Comp precisely identify your unique ovulation window, making it straightforward to time intercourse for the best possible chance of success. Fertility tracking puts the power in your hands.
Works Well with Irregular Cycles
If you have an irregular cycle or have been told that hormone imbalances may be affecting your fertility, pinpointing your ovulation and most fertile days becomes even more important.
If your partner has sperm motility or vitality concerns, timing intercourse to coincide closely with the days leading up to ovulation is also critical.
Based on your basal body temperature data and our unique algorithm, fertile days are shown in a specific colour and your predicted ovulation day is indicated with a flashing light. This simple system lets you and your partner know when the time is right.
Each morning, your temperature reading and menstruation input are all Daysy and Lady-Comp need to show you whether you are fertile, possibly fertile, or not fertile that day.
If you're working with a fertility specialist, your cycle data can be highly valuable to them. Daysy users can easily share data via the DaysyDay app by email.
DaysyDay App: Your Window Into Fertility Health
The DaysyDay companion app lets you view your past cycles and upcoming fertile days in a calendar format. You can look back to see exactly when you conceived, or plan ahead to make sure you don't miss your most fertile days. Time date nights, travel, or time at home around your cycle with ease.
DaysyDay also lets you log sexual intercourse, add personal notes, record cervical fluid observations, and track pregnancy tests, so your entire conception journey is in one place on your smartphone. Once you do conceive, it becomes a record of your baby's very first days.
With Lady-Comp, Your Fertility Data Is Always at Hand
Lady-Comp displays your current cycle curve directly on screen. You can also upload your data via the analyser on our website, print it out, or email it to your doctor. This gives your gynaecologist valuable insight into your cycle health and any factors that may be affecting your ability to conceive.
- Log the days intercourse took place ("SI-entry") to track planning and monitor the probability of pregnancy.
- Possible pregnancy is flagged as early as 16 days post-ovulation, with probable pregnancy indicators appearing from 18 days. Lady-Comp detects the characteristic temperature deviation from your extrapolated normal curves and alerts you early and reliably.
- Conception date display: once pregnancy is confirmed, you'll know exactly which day intercourse led to conception.
- Predicted due date: because Lady-Comp knows your conception date, it can calculate your expected birth date more accurately than the standard method based on the first day of your last period.
Early Pregnancy Detection
Both Daysy and Lady-Comp use your basal body temperature data to identify fertile days, and this same data can indicate a potential pregnancy in its earliest stages. When BBT remains elevated for more than 18 days, both devices register a possible successful conception. A second temperature rise may also occur as a result of the fertilised egg implanting in the uterine wall, typically 6 to 12 days after ovulation.
Daysy signals a possible pregnancy by flashing all three lights (red, green, and yellow) simultaneously, then shows all lights solidly lit as the likelihood increases. In the DaysyDay app, your temperature chart turns blue.
This gives you a clear signal of when to take a pregnancy test, making the two-week wait a little less stressful.
Important: Daysy is not a pregnancy test. To confirm a pregnancy, please take a standard test or consult your doctor.
