Most period apps are built by men

I wanted a cycle app that doesn't feel like it was built by a man who has never had a period.

No man has ever taken an ovulation test day after day, waited anxiously for a pregnancy test, or felt what a cycle really feels like. Yet most period apps come from them — pink, playful, out of touch with reality. Luna does it differently: honest, calm and grown-up.

First signs

What happens

PMS-like signs such as pulling or tender breasts are possible — with or without a pregnancy.

Hormones

hCG rises in a pregnancy while progesterone stays high.

Possible signs

PMS-like complaintsMood swingsBreast tenderness

Signs are individual — they may or may not occur and are not reliable proof.

Pregnancy test

A test is fairly reliable now.
