Bluma
Private period tracker that works offline
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.
Hey Product Hunters! 👋 I'm Maribel, the creator of Bluma.
I was concerned about how period trackers handle such intimate health data. I tried local-storage alternatives but they felt clunky and lacked features I needed. So I built Bluma, because I didn't want to keep choosing between privacy and a good experience.
Bluma is for anyone who wants to understand their menstrual cycle without worrying about where their health data ends up.
Why try it?
🗓️ Get predictions for your next period and fertile window so you're always prepared. 📝 Track periods, symptoms and moods to uncover patterns over time. 🔒 Offline, encrypted, open source. No account, no ads, no leaks. 🔄 Encrypted backups you can restore anytime.
I’d love your honest feedback! What would make Bluma a must-have for you?
