Your body is
changing.
So should your
tracker.

Why perimenopause deserves a tracker of its own
Perimenopause can last 4 to 10 years. Symptoms shift, cycles get unpredictable, and most period apps weren't built for it. Luna Flux is — without locking you into a clinical-sounding interface or asking for your data.
Built for women experiencing the first signs of perimenopause, but useful for any woman who wants a private, structured way to notice how her body is changing.
Ready when you are.
Two minutes to set up. No email verification. No "free trial". Just open it and start.
