Period tracking apps are used to track periods and often predict when the next one is due. The main feature of period tracking apps is that they enable you to record their menstrual cycle, which can help you become more aware of your menstrual cycle. Some period tracking apps include other features. Examples include symptom tracking (eg, the amount of bleeding, pain, mood, etc) or predictions about the timing of ovulation and the ‘fertile window’ (which may assist with conception). They may also include screening and clinical advice for endometriosis(external link), polycystic ovary syndrome(external link) (PCOS) and menopause.(external link)
Period tracking apps may not always be accurate
- Most apps are based on predictions: Period tracking apps are based on predictions of ovulation timing and this may not be accurate for everyone. The apps are often based on algorithms, which usually ask for dates of menstruation, information about your cycles and sometimes temperature, urine tests, and cervical fluid. Based on the information and algorithms, the apps estimate the date of your next period and your date of ovulation. Note, these may not always be accurate.
- Privacy of your information: Period tracking apps ask you for information when you sign up (eg, typical period cycle and length) and then ask ongoing information about dates of your periods. Some apps don't say how your data is used – for example whether the information is sold or shared to other companies.
- Lack of New Zealand specific apps: Currently there are no Aotearoa New Zealand specific period tracking apps, which offer guidance based on New Zealand guidelines. Most are overseas apps that include generic or mostly American information.
