Period apps show you a red dot. Today treats your cycle as the rhythm it is — heavy days arrive with rest already scheduled, PMS gets met with gentler plans, ovulation gets the focus it deserves, and nothing you log is ever shared.
Generic period apps tell you when to expect your period and little else. The useful part of cycle tracking is what you do differently on day 21 versus day 7 — and that takes a plan, not a calendar.
Today knows roughly where you are in your cycle and reshapes the week around it — deep work and important asks during high-energy days, lighter schedules and rest when your body is asking for it. Nothing medical, everything a plan.
From your past logs it expects the rough days before your period — and pre-empts them: fewer evening commitments, a gentler training load, cravings acknowledged in the meal plan instead of fought.
Hard sessions land in high-energy weeks, easy recovery days protect the luteal phase, and heavy days default to a walk — always tunable by how you actually feel when you log.
Period start, pain, flow, mood, sleep — each takes seconds. Over months Today connects the dots into a calm summary you own, and can bring to a clinician if you want one.
Some phases need more water and less caffeine. Today adjusts both quietly — no lecture, no extra job.
The PMS week gets the snacks you actually want on the list, while protein and vegetables stay on the plate. No willpower required on the low days.
Luteal weeks often sleep worse. Today pulls the wind-down earlier and sets a caffeine cut-off — only when your own logs suggest it.
Irregular month? Today says “not sure” and shortens its horizon instead of guessing. It never pretends a calendar knows more than your body does.
Same app — the plan flexes with your phase, your training and the kind of month you're having.
Follicular weeks get the hard intervals and heavy lifts; luteal weeks back off into zone 2 and mobility. Today schedules both around her actual calendar — races included.
Every month, the days before her period turned small things into fires. Today now sees them coming — it moves non-urgent calls, guards her wind-down and keeps the week human-sized.
Her cycle doesn't line up with any app's prediction. Today learns from what she logs — symptoms, sleep, period start — keeps predictions short and honest, and never punishes a longer cycle.
One shared calendar, two people, and a month with its own rhythm. Heavy days sit on the shared calendar only if she chooses — Today never shares anything on its own.
Period start, heavy days, PMS or pain when they show up — ten-second logs. Today starts gentle and gets smarter with every month.
From your own history it builds a picture of your cycle length, symptoms and energy — then maps the coming weeks onto your real calendar.
Training, deadlines, meals and wind-down reshape around the phase. Every change is a suggestion you approve — and reversible any time.

Today is a lifestyle and organisation assistant. It helps you plan around your cycle — it does not diagnose, treat or prevent any condition, and it is not contraception. For medical questions, talk to your clinician.
Today is available now and free to use. Log in and you get cycle-aware planning, one-tap symptom logs and the phase-aware calendar on iPhone, Android, macOS and the web.
From what you log it estimates your period window and, if you log them, ovulation symptoms. Predictions stay honest: when your cycle varies, it says so and shortens its horizon. Fertile-window notes are calendar awareness — not contraception.
Yes. Everything Today remembers about you is inspectable, correctable and deletable — deletions are real, and nothing is shared with anyone unless you choose to share it.
Today works from your own history, not a 28-day average, so irregular cycles are handled fine — it just keeps predictions short and marks them uncertain. If you're concerned about what irregularity might mean, that's a question for a clinician; Today isn't a diagnostic tool.
Nothing runs automatically. Today proposes adjustments based on your phase and your logged energy — you approve each one, and you can keep your training exactly as it is.
No — logging your period start and symptoms is enough to start. A wearable adds HRV, temperature and sleep signals that sharpen phase estimates over time, but every signal is optional.
Only if you explicitly share a card or calendar with them. Sharing is optional, limited to what you choose, and revocable at any time.
Heavy days arrive with rest already scheduled, PMS gets a softer week, and training follows your real energy. Free to use on iPhone, Android, macOS and the web.
