The things no plan
ever accounts for.

If any of this feels familiar, Phasly was made with you in mind.

"Same workout, totally different week"
One week a session feels easy, the next the exact same one floors you — and no app explains why.
Phasly reads your phase and adjusts the load so you stop guessing.
"I fall apart before my period"
Energy, mood and motivation crash in PMS week — so you skip workouts and feel guilty about it.
Your plan eases off on purpose, so you stay consistent instead of quitting.
"I came off the pill and feel lost"
After years on birth control, your natural cycle or PMOS (PCOS) feels unpredictable and confusing.
Phasly learns your real pattern and trains with it — even when it's irregular.
"I push through and burn out"
You follow a generic program that ignores recovery — and end up tired, plateaued or hurt.
Train with your biology and progress without the burnout.

Your phases.
Your smarter plan.

Your natural cycle has the four classic phases below. Other modes have their own rhythm. pack weeks, trimesters, recovery stages or weekly templates. Phasly adapts to whichever you're in.

See all 10 cycle modes →

Menstrual
Days 1–5
Rest & recover
Energy often dips. lean into recovery, with zero guilt for going easy.
Follicular
Days 6–13
Build & learn
Energy climbs. a good window to build strength and add load.
Ovulatory
Days 14–16
Go for it
Many feel strongest. a great time for your hardest sessions.
Luteal
Days 17–28
Maintain & wind down
Early luteal still supports strength; late luteal eases off.

Whatever your body's
doing right now.

Regular, irregular, paused or changing. Phasly runs 10 cycle modes so it meets you exactly where you are, with a coach who understands what your body is going through.

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

Adelina, founder of Phasly

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. To unlock personalised workouts and the AI Coach, you start a 30-day free trial of Phasly Plus, then $14.99/mo (or $89.99/year). The first 500 founding members get 10% off the annual plan for life. Cancel anytime.

Soon. and everyone on the early-access list will get in first, before public launch. (The first 500 to join also get the founding-member discount.)
