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?

Mama Bloom is a private cycle journal. It keeps your record on your iPhone — there is no account, no server, no ads and no tracking — and it tells you the truth about forecasts: a period is predicted as an honest range, never a fake-precise date. Log flow, pain, sleep, mood, energy and symptoms in seconds. The living record organizes every cycle you keep; Insights show the evidence behind every statement, so you can check the app's work; the Learn library explains cycles calmly, with visible sources and clear boundaries. Privacy, by architecture: the record is protected by iOS Data Protection, the optional widgets are discreet by default, the app can lock behind Face ID, exports leave out intimate categories unless you choose otherwise, and an optional sealed backup lives in your own iCloud, encrypted on your device with a key Mama Bloom never has. One action deletes everything, including the backup. The optional Private Edition subscription adds cycle-to-cycle comparison, forecast memory and guided visual editions. Payment is handled by the App Store; prices are shown before you confirm. Mama Bloom is a wellness journal: a record for reflection, not a medical decision and not contraception. It shows no fertile-window or ovulation estimates, and forecasts can be wrong — when a health decision matters, talk to a professional.
