Read full descriptionHide full description
A completely new perspective on your cycle and your everyday life. MORE THAN SYMPTOMS. Most cycle apps only let you track symptoms. PHASES goes further. Focus on what matters most in your everyday life. Not just symptoms, but also what you did and experienced. Sports, nutrition, date nights, family moments, relationship highs and lows, work stress, social events — everything that matters to you. Clearly presented in a unique vertical calendar. FOR MEN, TOO. Why are cycle apps always made just for women? Enter your partner's period and alongside it your own life. Because HER cycle has an impact on YOUR relationship life when it comes to moods and libido. So you know what's going on — for a better mutual understanding. DISCOVER PATTERNS you haven't seen before. When you keep everything in one place, connections become visible. How does your energy change around your ovulation, or your partner's? How do sleep, nutrition, and exercise relate to how you feel? PHASES makes these patterns visible so you can understand yourself better and plan smarter. PRIVACY BY DESIGN. Cycle apps that store data on servers are a no-go. PHASES stores everything exclusively on your device. No account required. No server. No tracking. No third parties. Your entries never leave your smartphone. FEATURES. - Unique vertical calendar - Fully customizable categories and entries - Track your period and receive a forecast - Bleeding isn't the same as your period.

No cloud, no tracking - Core features usable without a subscription

Verdict
The clearest difference is in-app purchases: PHASES. Cycle Tracker & Diary at none against Periodically's 1. Periodically's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (13.0 vs 26.2). On price, ads and device support there is nothing between them.
