Counting from memory
“Was it the 3rd or the 10th?” Most of us track our period in our heads, so a late one or a change slips past for months.

Sound familiar?
Your body talks. It’s hard to keep up.
You shouldn’t need a spreadsheet, a stranger’s forum or a data plan to understand your own cycle.
Apps that want too much
An account before anything else, data you can’t spare, and somewhere in the cloud, your most private details.
Questions you can’t ask
Is this discharge normal? Is this much pain okay? Too awkward for friends, too scary for search results.
Her Rhythm is the calm, private answer: your cycle, your moods and your sexual health, understood in seconds a day.

Six kind tools. One quiet app.

Short, judgement-free guides on period pain, heavy periods, PCOS, infections and contraception myths, with honest advice on when to see a doctor.
Your cycle, gently explained
Four seasons, every month.
Your cycle is more than your period. Knowing its phases helps you understand your energy, your moods and your body, and plan around them.
28 days
on average. Anywhere from 21 to 35 is normal.
Period
Days 1–5
Your lining sheds. Cramps, low energy and cravings are common. Rest is allowed.
Follicular
Days 6–13
Oestrogen rises. Many people feel brighter, more social and full of ideas.
Ovulation
Around day 14
An egg is released and pregnancy is most likely. Some notice clear, stretchy discharge.
Luteal
Days 15–28
Progesterone takes over. Bloating, tender breasts and mood dips can show up before your period.
Every body is different. Her Rhythm learns your rhythm and shows where you are today, so the textbook version never has to fit.
Watch · 1 minute
Nine days late, and you only noticed today?
Most of us track it from memory, so the warning signs slip past. Here is how Her Rhythm helps you notice, gently and privately.
Made for real life
Built for the women other apps forgot.
The big trackers were built for somewhere else. Her Rhythm starts with the questions women here actually ask, on the phones we actually use.
Written for us
Fibroids, PCOS, sickle cell and the contraception myths we grew up hearing, answered plainly.
No shame, ever
Warm, grown-up language. No baby-pink condescension, no lectures, no judgement.
Kind to your data
Works fully offline and stays light, so it runs well on older phones and small data plans.
Honest about limits
It informs and gently flags. It never diagnoses, and it always tells you when to see a doctor.
Day or night, your colour
Soft by day. Plum by night.
A warm light theme for daytime and a deep plum night theme that’s easy on the eyes at bedtime. Then make it yours: pick an accent, or any colour you love.

Questions
Ask us anything.
More answers in Help & FAQ, or email herrhythm@mlabs.ng. A real person reads every message.
Is Her Rhythm free?
Yes. Period and fertile-window predictions, the daily log, reminders, insights, the doctor report, the guides and backups are all free, and there are no ads. Her Rhythm Plus is one optional lifetime purchase that adds a year of cycle history and extra icon colours. There is no subscription.
Who can see what I log?
Only you. There is no account and no Her Rhythm server. Everything you log is stored on your phone, secured, and never sent to us. We don’t run ads or analytics, and we will never sell or share your data, because we never have it.
When is Her Rhythm coming to iPhone?
Soon. Her Rhythm is available on Android today and the iPhone app is on its way. Leave your email on the iPhone page and we’ll tell you the day it lands.
How accurate are the predictions?
They’re based on your own history, not an average stranger’s. Predictions get sharper after about three cycles, and the next period is shown with a likely range so you know how sure the estimate is. Logging ovulation tests or your waking temperature helps Her Rhythm learn your rhythm faster.
Can I use Her Rhythm to avoid pregnancy?
No. Fertile-window estimates are not birth control, and Her Rhythm says so wherever they appear. If you want to avoid pregnancy, talk to a nurse or doctor about contraception. Her Rhythm can then remind you about your pill, injection, implant, coil, ring or patch.
My cycles are irregular. Will it still work?
Yes. Her Rhythm shows wider ranges when your cycles vary and gently flags when they look irregular, with what to mention to a doctor. Irregular cycles can have many causes, including PCOS, stress and thyroid issues, so it’s worth getting checked if it keeps happening.
Know your body. Keep it private.
