Luna was created by someone who knows what it’s like to live with PMDD. After years of struggling without the right support, I wanted to build the app I wish I had — a calm, supportive space where everything you need is in one place.

Luna helps you track your cycle, manage symptoms, journal, and feel supported by a community that truly understands. It’s more than an app — it’s your daily companion through PMDD.

Luna understands the unique challenges of Premenstrual Dysphoric Disorder. Track your cycles, connect with supportive community, and access personalized wellness tools designed specifically for PMDD management.
