What's New in My Body's BFF
2.3.0
October 11, 2026
Your mood, energy and focus shift with your hormones, every month. My Body's BFF shows you your own pattern, so "why am I like this today?" becomes "it's that week again, and now I know why." Not a date on a calendar. A phase. YOUR PATTERNS, NOT THE AVERAGE WOMAN'S See which hormone phase you're likely in today, and what that has meant for you before Patterns from your own logs, with the receipts: "fatigue on 8 of your 11 luteal days" A weekly look ahead built only from your own data. Not enough data yet? It shows your progress instead of guessing Predictions from your own cycle length, not a textbook 28 days LOG IN SECONDS Four sliders: mood, energy, stress, sleep Period, symptoms, feelings, your day and food in one screen The app opens what fits your phase first, and your own most-logged items come first FOR YOUR HARDEST DAYS Short tools per phase, built on ACT and CBT by a psychologist A clear PDF overview of your cycles and symptoms to take to your doctor YOUR DATA STAYS YOURS No ads. No selling. No tracking SDKs Export or delete everything, any time ALSO Optional LH test and temperature (BBT) logging A mode for hormonal contraception Share your phase with a partner, if you want to Your phases as inner seasons: Winter, Spring, Summer, Autumn Dark mode Built by a psychologist. No team, no investors asking for your data. My Body's BFF does not diagnose anything and is not a contraceptive or fertility tool. Period pain that stops your life is not something to endure quietly: talk to a doctor.
