Timing for Sex
Knowing your ovulation cycle, you can manage your family planning by avoiding sex during your fertile window. Also, Femometer allows you to track your sexual activity, giving you better awareness and control over your reproductive health.

No hormone & Side Effect
Fertility awareness methods (FAMs) are safer and more cost-effective with no side effects. While the effectiveness may be slightly lower than hormonal pills, accurate ovulation predictor can still have a very good performance on family planning.

Spotting Records
The color and volume of period blood can vary from cycle to cycle and are important indicators of women's health. Recording your spotting helps you understand your menstruation, and learn about your reproductive health.

PMS Symptoms Records
Premenstrual syndrome (PMS) is a collection of physical, emotional, and behavioral symptoms that some women experience in the weeks before their period. By recording these symptoms, you can help your doctor confirm a diagnosis and determine the best treatment.

Cervical Mucus Chart
Hormones cause your cervical mucus to change in texture, volume, and color throughout your cycle, which can help identify when you're most fertile. An abnormal change in your cervical mucus may indicate potential health concerns.
