Dot Period Tracker & Fertility Tracker

Dot™ is the only fertility tracker and period tracker app that can be used to prevent pregnancy as well as to plan pregnancy using just your period dates. Dot uses advanced data science to identify your pregnancy risk for each day of your cycle. Dot makes modern fertility awareness easy! Every day it accurately shows you whether your chance of pregnancy is High, Medium or Low.
Dot’s proprietary algorithm requires only your period start dates to produce accurate and personalized information. The Dot fertility tracker app (free) can also be used as a period tracker, fertility calendar, period calendar, period calculator, and ovulation calculator.
Dot fertility tracker has been described by global health experts as a "game changer for women's health".
DOT FERTILITY TRACKER GETS SMARTER WITH USE
Dot’s proprietary algorithm uses ongoing statistical analysis to determine your pregnancy chances for each day of your cycle. The more cycle dates you enter, the more tailored Dot’s results. Whether you are using it as a period tracker, fertility monitor, or ovulation predictor.
HOW IS DOT FERTILITY TRACKER DIFFERENT?
Dot fertility tracker is one of a kind among period tracking apps. It is more advanced than a period tracker in that it gives you accurate information that you can actually use to prevent pregnancy or get pregnant fast. And it’s easier to use than other fertility awareness methods. No need for extensive charting and daily temperature taking, whether you are using it as birth control or for conception.
Dot has been tested extensively for accuracy. Dot fertility tracker is based on years of research and is undergoing the first contraceptive efficacy study on a fertility app.
WHO CAN USE DOT FERTILITY TRACKER?
Anyone can use Dot as a menstrual cycle tracker, period tracker, or to get pregnant. If you use Dot for pregnancy prevention, it is recommended that you have cycles between 20-40 days long with less than 10 days variation in length. Dot will let you know if your cycles are ever outside this range. Additionally, it is recommended that users should be able to manage their fertile days by using an effective back-up birth control method or avoiding intercourse on high-risk days.
