Flo Zyklus- & Periodenkalender

What Flo covers and who it is for

Flo is a menstrual cycle tracker that also covers fertility, pregnancy and perimenopause. A person logging periods, trying to understand their ovulation, pregnant, or noticing perimenopause changes can use the same app across those stages.

The features below are grouped by what you are trying to follow: the cycle, pregnancy, the transition out of periods, and how your account and conversations are handled.

Logging periods and predicting ovulation

Period tracking works for both regular and irregular cycles, so it does not assume a fixed schedule. Alongside it, the app predicts ovulation and gives guidance on learning to spot fertile signs.

Ovulation prediction and fertile sign guidance are the parts of the app aimed at people who want to understand where they are in their cycle.

Pregnancy tracking and perimenopause symptoms

The pregnancy tracker follows changes to the baby and to the body through pregnancy. It sits alongside the cycle tools, so one app can carry you from period tracking into pregnancy.

A separate part of the app explores common perimenopause symptoms for people in that stage of life.

Anonymous Mode and data protection

Anonymous Mode lets you use Flo without linking your name, email address or other personal identifiers. It is the option for keeping tracking data separate from who you are.

The developer lists ISO 27001 and ISO 27701 certifications, which cover information security and privacy management. The listing says Flo is the only period tracking app holding both.

Secret Chats with other members

Secret Chats connect you with other members who share tips and personal experiences. This puts peer conversation inside the app, next to the tracking tools.
