Bluma

Bluma とは？

Most period apps send your health data to a server. Bluma doesn't. Track your periods, ovulation, symptoms, and moods without worrying about where your health data ends up. Get predictions, spot patterns, and better understand your menstrual cycle. Everything stays on your device, offline and encrypted. No account. No ads. No leaks. Open source and available on Android, with iOS support coming soon.
