HerBattery - The cycle awareness app built for men. No guessing.

by•
Most period apps are built for women. HerBattery is built for the man who wants to understand her. A battery on your homescreen shows exactly where she is in her cycle — her energy, her mood, her desire. 7 phases, color-coded, always one glance away. 100% offline. No account. No cloud. Your data never leaves the phone. 32 languages. Less than a coffee a year (€9.99), with a 7-day free trial — no credit card needed. She's not random. You just didn't have the data.

Hi Product Hunt! 👋 I'm Iulian, an IT teacher from Romania. Like most men, I spent years confused about why some weeks were amazing in my relationship and others felt like walking on eggshells. Nobody ever taught us how the menstrual cycle actually affects mood, energy, and connection. So I built HerBattery — a dead-simple app that shows her cycle as a battery on your homescreen. Green means high energy. Red means bring chocolate and patience. 😄 What makes it different: 🔋 The battery metaphor — you understand it instantly 📱 Homescreen widget — no need to open the app 🔒 100% offline — no account, no cloud, total privacy 🌍 32 languages 💶 €9.99/YEAR (not month) — less than a coffee a year 7-day free trial, no credit card. I'd love your feedback — especially from couples who try it together!
