“Stop guesstimating when to try for a baby. Track ovulation to know your fertile days in advance.”

Why Tracking Ovulation As Age Goes Up?

With age, the length of fertile window decreases, which means your chance of getting pregnant declines. Tracking ovulation can predict your most fertile days to boost fertility, especially for those with irregular cycles or at age 30s, or 40s. IVY103 pinpoints your ovulation cycle, so you won’t miss any chance to conceive!

Giving Accurate Predictions Even If You Have Irregular Cycles!


If you have irregular periods, it can be challenging to predict your next ovulation day. Fortunately, by tracking LH levels with the assistance of IVY103, you can obtain a more precise ovulation prediction.

IVY103 is designed to detect even subtle changes in LH levels within your body. When it begins to rise, it indicates that ovulation may occur within the next 2-3 days.

For people with irregular periods caused by PCOS, tracking two indicators, Basal Body Temperature (BBT) and LH levels, for three months allows the APP to analyze sufficient data for more accurate predictions.
