Hi, I'm Adelina.
I built Phasly for us.

I came off the pill after years. and met my real cycle for the first time. Suddenly it clicked: the weeks I felt unstoppable, and the weeks the same workout flattened me.
I'd been grinding through plans built for a man's 24-hour hormones, blaming myself when my body didn't play along. It wasn't me. I was training against my own biology.
No app trained with the female cycle. so I built one. And I want every woman, whatever her cycle's doing, to open it and feel: finally, something made for me.
That's Phasly. Come build it with me.. Adelina 💗
Good questions.
Yes. Your intimate activity lives in a separate, private space, and your data is never sold. Phasly is built privacy-first. your body is your business.
Yes. Phasly is a cycle-aware period tracker, and a fitness app. Most period-tracker apps only log your dates; Phasly turns your cycle into cycle-sync workouts that adapt to your phase and how you feel each day. So you get both. period tracking and personalised, phase-based training, in one app.
Not at all. Phasly runs ten cycle modes. natural cycle, hormonal IUD (with or without periods), the pill / patch / ring, PMOS (PCOS), perimenopause (with or without a cycle), menopause, pregnancy and postpartum. so it works whether your cycle is regular, irregular, paused or changing.
We're careful here, because the science deserves honesty. There's a growing body of peer-reviewed research on how ovarian hormones (estrogen and progesterone) influence strength, recovery, energy, sleep and injury risk across the menstrual cycle. but the findings vary between individuals, and no one should overpromise a one-size-fits-all "cycle protocol." So Phasly treats the research as a starting framework, not a rulebook. Every recommendation is cross-referenced with published studies and reviewed by medical professionals, and then it's personalised to you.
No. and that's the whole point. Research is clear that your cycle phase is only one input: sleep, stress, training load and how you genuinely feel day to day all shape your energy and recovery just as much. So alongside your phase, Phasly tracks a quick daily check-in. energy, sleep, readiness, mood and symptoms. and adapts your plan to what your body is telling you right now, not just where you are in the month. The more you log, the more it learns your real, personal pattern. Two women on the same cycle day can get different plans, because they feel different.
Cycle tracking. calendar, phases, hormone diagram and daily check-in. is free forever, in all 10 cycle modes.
