Hey Product Hunt! 👋

We're CosmicFlow Labs, and we built HerHabits because we were tired of seeing women blame themselves for "failing" at habits.

THE PROBLEM WE SAW:

Every month, the same pattern:

Week 1: Crushing morning routines: meditation, journaling, gym, all of it
Week 2: Still going strong, adding new habits
Week 3: Starting to slip... feeling less motivated
Week 4: Can't get out of bed, abandon everything, feel terrible

Women thought they were just inconsistent. Turns out, they were fighting biology.

THE AHA MOMENT:

Your menstrual cycle has 4 distinct phases, each with WILDLY different energy levels:

🩸 Menstrual (Days 1-5): Low energy, need rest

🌱 Follicular (Days 6-13): Rising energy, great for new habits

✨ Ovulation (Days 14-16): Peak energy and confidence

🌙 Luteal (Days 17-28): Declining energy, need more support

When you track habits with PHASE instead of by DAY, everything makes sense.

WHAT HERHABITS DOES:

Shows you which habits work in which phase
- Example: "Meditation: 90% success in Follicular, 35% in Luteal"
Plans your whole month based on your cycle
- Schedule intense projects during high-energy weeks, rest during low-energy weeks
Gives phase-specific insights
Privacy-first design
- Data stays on the user's device. No accounts, no cloud, no selling cycle data.
One-time purchase, no subscription
- $9.99 lifetime access. That's it. Forever.

WHO IT'S FOR:
