Plan your week, not just your day
Bloomelle forecasts the days ahead from your cycle so you can pick the right moment for workouts, focus work, big decisions, or rest — before it sneaks up on you. Not a symptom tracker.

See your week, not just today
Most cycle tools tell you what's happening right now and leave you to remember it tomorrow. Bloomelle takes your last period start date and average cycle length and turns them into a 7-day-ahead forecast, so you can plan a workout, a big decision, or a lighter day before you get there — not after.
What's inside
Four simple pieces, nothing you have to fill in every day:
Week-ahead forecast
Your last period start date and average cycle length turn into today's phase plus a 7-day-ahead strip — no manual logging required.
Daily suggestions
Softened, non-prescriptive picks for workouts, focus work, big decisions, and rest — always "may suit," never a guarantee.
2-input setup
Just a start date and a cycle length to begin. Both stay editable, since most people don't have an exact 28-day cycle.
Daily check-in
A ten-second log of energy, focus, and mood, plus whether that day's suggestion actually fit — the ritual that makes this more than a one-time calculator.
Cycles are different for everyone
The textbook cycle is 28 days, but real ones vary. The NHS says cycles commonly run from every 21 to 35 days, and the US Office on Women's Health describes 24 to 38 days as regular, adding that length can change from month to month and with age. That's why Bloomelle starts from your own average cycle length, which you can edit any time, instead of assuming 28 days.
The four phases in a minute, per Cleveland Clinic: the menstrual phase starts on the first day of your period; the follicular phase runs from the start of the period until ovulation, with estrogen rising; ovulation is when an egg is released, around the middle of a typical 28-day cycle; and the luteal phase runs from ovulation until the next period, with progesterone rising and then falling.
How much the phase matters for planning your week is less clear. A 2023 review of strength and resistance training concluded it is premature to say that cycle phase meaningfully changes performance, recommended an individual approach, and noted that cycle-related symptoms can affect some people, so tracking how you feel can help. That's why Bloomelle's suggestions are starting points, and the daily check-in shows what actually fits you.
Not a substitute for medical advice
Many people notice real patterns across their cycle, but the science behind phase-based performance is still limited and mixed — Bloomelle's forecast is a planning tool built around what you notice, not a diagnosis or a clinical recommendation. If something about your cycle concerns you, talk to a doctor rather than relying on an app.

Private by design

Frequently asked questions
Is Bloomelle a symptom tracker?
No. Bloomelle doesn't log symptoms day by day — it forecasts your coming week from your last period start date and average cycle length, and suggests which days may suit workouts, focus work, big decisions, or rest.
Is this based on science?
Many people notice real patterns across their cycle, but the research on phase-based performance is still limited and mixed. Bloomelle frames every suggestion as "may suit," never a guarantee, and it's a planning tool, not medical advice.
Is Bloomelle available yet?
Yes. Bloomelle is free on the iOS App Store. An Android version is in testing — leave your email and we'll let you know when it's available.
Do I need an account, and where does my data go?
No account and no sign-up. Your cycle dates and check-in history stay on your device; the app sends only limited usage analytics, never your period dates.
How long is a typical cycle, and what if mine is irregular?
A cycle is often quoted as 28 days, but sources such as the NHS and the US Office on Women's Health describe a normal range of roughly 21 to 38 days, and it can change from month to month. Bloomelle starts from your own average cycle length, which you can edit at any time. If your cycles are very irregular, the forecast will be less reliable, and it's worth talking to a doctor about anything that concerns you.
Is there a printable version?
Yes. There's a free printable weekly cycle planner with a daily check-in and a notes page, in A4 and US Letter. No signup.
