HerBattery vs Lune Cycle Tracker

HerBattery Understand her cycle. Build a stronger relationship. Sometimes the problem isn't love. It's timing. HerBattery helps you understand your partner's natural monthly rhythm through a simple battery-inspired visualization. Know what to expect, communicate with more empathy, and support her when it matters most. Built for partners. Designed for understanding. Private by design. She doesn't need the app. WHY HERBATTERY? Most cycle apps are built for women. HerBattery is built for the partner. Instead of charts, symptoms, and endless tracking, HerBattery transforms the menstrual cycle into something everyone instantly understands: a battery. A battery doesn't judge. It simply shows how much energy is available. Some days there's more. Some days there's less. One glance is enough. Not to predict her. Not to label her. Simply to understand her better. SIMPLE SETUP Getting started takes less than a minute. Just enter: * The first day of her last period * Her average cycle length That's all. HerBattery keeps everything up to date automatically. No daily logging. No accounts. No ongoing setup. UNDERSTAND THE FOUR PHASES Menstrual Lower-energy days often call for more patience, warmth, and practical support. Follicular Energy usually begins to return. A great time for plans, adventures, and meaningful conversations. Ovulation Often the highest-energy phase. Connection, confidence, and shared experiences may come more naturally. Luteal Energy gradually shifts. Consistency, empathy, and emotional awareness become especially valuable. PRIVATE BY DESIGN Privacy isn't a feature. It's the foundation. Your partner doesn't need to install anything. No accounts. No cloud. No servers. No tracking. No data collection. Nothing is uploaded. Everything stays on your device. Because understanding someone should never require giving away their private health data. FEATURES * Battery-inspired daily visualization * 28-day cycle overview * Daily relationship insights * Home Screen widgets * 100% offline * Zero data collection * No account required * No ads * Supports 32 languages * GDPR compliant SIMPLE PRICING * 7-day free trial * No credit card required * EUR 9.99 per year Less than EUR 1 per month. IMPORTANT HerBattery is designed for relationship awareness and educational purposes. It is not intended for medical, diagnostic, fertility, or contraceptive use.

Lune is a simple, private period tracker designed to help you understand your cycle without compromising your health data. Log your period dates and Lune automatically predicts your next period, fertile window, and ovulation day. The more cycles you log, the more accurate the predictions become. Features: • Track your menstrual cycle and predict future periods • See your fertile window and estimated ovulation day • Understand your cycle phase (menstrual, follicular, ovulation, luteal) • Gentle reminders 2 days before your next expected period • Beautiful, easy-to-read week strip showing where you are in your cycle Your privacy is the priority: Lune stores all data locally on your device only. No account required. No data is ever uploaded to a server, shared with third parties, sold, or used for advertising — ever. Uninstalling the app permanently deletes everything. Lune is not a medical device and does not provide medical advice. Cycle predictions are estimates based on your logged history.
