Know a breakout is coming. Not that it's here.
Cirra learns your cycle and tells you what your skin is about to do next. Breakouts, oil, dryness, sensitivity — on your face, back and chest. Then it gives you a plan to stay ahead of it.

The whole idea
This isn't a skin diary.
Logging apps give you a record of breakouts you couldn't stop. Great for your dermatologist. Useless at 6am when a spot shows up. Cirra does the opposite.
Tracking apps
Tell you what already happened.
- You photograph a spot that showed up days ago
- You find out in the mirror, same as everyone else
- Every product you own is a reaction
- A chart of the damage, after the damage
Cirra
Tells you what's about to happen.
- Predicts your flare window before your skin reacts
- Warns you while you can still do something
- Tells you what to do and when to start
- Then checks whether it actually worked
Tracking is a record of what you couldn't stop.
Forecasting is your chance to stop it.
Who this is for
Most skin apps are built for everybody. This one isn't.
Most skincare apps group everyone together — men, women, teenagers, and try to solve for all. But the biggest thing driving your skin is your hormone cycle, which all other apps ignore.
Which is why your skin looks random from the outside. You've tried everything. Nothing sticks. It cleared up for a while and then came straight back. You were sure you'd left this behind in your teens.
If more than two of these hit, this was built for you.
And it's not just about breakouts.
You've usually got more than one thing going on at once. Oily one week, dry the next, sensitive on top of that, plus the redness that comes and goes.
They all run off the same cycle, so treating one on its own tends to make another one worse. You need to see the whole picture at the same time.
Cirra forecasts all of it, not just the spots.
Your skin isn't random. It's on a schedule.
Progesterone climbs through the back half of your cycle. Your oil glands catch up a couple of days later. Everything after that — the spot, the shine, the sensitivity — lands in the same stretch of days, month after month.
That lag is the whole opportunity. It's why a forecast works at all, and why starting early actually changes things.
Textbooks assume 28 days. Your cycle is your own, so Cirra learns yours instead of averaging you in with everybody else.
Tuned to you
Truly personalized. Not a cookie-cutter routine.
A routine off the internet is an average of strangers. Cirra builds something bespoke to you out of nine things it keeps learning about your skin.
Which phase you're in, how long yours really runs, and where your flare window sits.
Teens, adult-onset, PCOS, postpartum, perimenopause. The pattern shifts, so your plan does too.
Chin, jaw, cheeks, back, chest. Forecast separately, treated differently.
What you already use and how your skin took it, so nothing clashes or doubles up.
Dairy, sugar, whey — tested against your own flares. Not guessed from a blog post, or an AI that's never seen your history.
Sweat, friction, sports bras, the Saturday class that shows up as a Monday back breakout.
The nights under six hours, and what they do to your oil the week after.
Oil, dryness, sensitivity, how fast you mark and how long marks stick around.
It learns. Every cycle you record makes the next recommendation better, because it knows what actually worked on you.
No two people run on the same cycle, break out in the same places, or react the same way to the same thing. So no two plans should look the same either.
What it actually does
Predict, prompt, prove.
Every screen earns its spot by doing one of three jobs: seeing what's coming, telling you what to do about it, or checking whether it worked.
It knows why, not just when.
Cirra maps your skin onto your cycle and shows you the link. Which phase you're in, and exactly where your flare window sits.
Your pattern, in one screen.
You hear about it before your skin says anything.
When a flare window is coming, Cirra tells you — early enough to actually do something. How much warning you get depends on your own timing: you might flare a few days before your period, or closer to two weeks out.
The alert shows up while you can still stop it.
Then it tells you exactly what to do.
Not a product to buy. An ingredient to look for and a day to start. Calm your skin down before it starts stinging, or begin treating a flare before it ever shows up — timed to the week you're actually in.
No brand names. No affiliate links. Ever.
It was never just your face.
Your back and chest are the parts you never photograph and nobody ever asks about. Cirra forecasts each area on its own. Same cycle underneath, but they don't flare on the same day, and body skin needs different treatment.
You can't see your own back. Cirra can.
And it checks whether the plan worked.
Every forecast gets checked against what actually happened to your skin, measured against your own normal. Prevented, milder, or missed — said plainly, then used to sharpen the next one.
If it can't be wrong, it's a horoscope.
Or just ask it, like you'd ask a friend.
Ask it anything you'd ask a friend who happened to be a dermatologist and had read your whole history. Why your chin is breaking out again. Whether to use an acid this week. What to start before Saturday. Whether a new product is purging you or breaking you out.
It answers using your phase, your plan and every flare you've logged — not a generic article about salicylic acid.
Logging takes one tap. Asking takes one question.
Your products
Scan what you own. Check what you're about to buy.
Most of the time the thing you need is already on your shelf. You were just using it on the wrong days, or piling five things on at once and hoping one of them would stick.
So tell Cirra what you've got, and it stops guessing. Nothing it suggests will clash with what you already use, and when you're about to spend money on something new, you can check it first.
Scan what you own
Point your phone at the bottles on your shelf. Cirra reads the ingredients and learns what you're using, what it's for, and which days you use it.
Or just type it in
Don't feel like scanning? Type the main ingredients instead. That's plenty for Cirra to work with.
Check before you buy
Standing in a store, or halfway through an online checkout? Scan it first and find out whether it suits your skin and whether it fits your plan.
Completely optional. The forecast works either way — this just makes it sharper.
No brand deals. No affiliate links. Nobody is paying us to point you at their serum, so sometimes the answer is just “this one's fine, keep using it.”
The question everyone asks
“But my cycle is all over the place.”
Then you're exactly who this is for. Irregular cycles come with more skin trouble, not less — PCOS, coming off the pill, perimenopause, a stressful year. They all make your cycle harder to predict and your skin more reactive.
Which makes you the person regular skincare apps help the least.
It learns your pattern, messy or not
It doesn't need a textbook 28 days. It works from whatever your cycle actually does, and gets sharper the longer you use it.
It spots when things change
Coming off the pill, a new stage of life, a run of stressful months — when your pattern shifts, Cirra picks it up and adjusts.
It tells you how sure it is
When your cycle is less predictable, Cirra says so instead of faking certainty. You always know how much to trust today's forecast.
Built for you, not around you.
What changes
Clearer than last cycle. Then clearer than that one.
Not a miracle, and not overnight. Something better — a month you can see coming, and the end of a fight you've been losing from behind for years.
Getting ambushed
You stop waking up to something that started days ago. You know the week before, and by the time it would've hit, you've already been working on it.
Wondering if it's you
It was never your willpower, your pillowcase or your cleanser. It's a hormone on a schedule, and now you can finally see the schedule.
Buying blind
No more $50 experiments you never finish. You get told what an ingredient needs to do and which days to use it, so your money goes on things that can actually work.
Randomness
You know which week your skin peaks and which week it dips, so you can plan around it. Put the wedding, the photos and the big night in your good week, and keep the facial out of the week it'd hurt.
Marks that pile up
Fewer flares hitting full strength means fewer dark marks left behind — and those stick around for months after the spot is gone. That's the part you'd still see next summer.
Gets better every month
Every cycle you log teaches it something. Month six beats month one, because by then it knows your timing, your zones, and what actually worked on you.
Free to join. No card. Leave whenever you want.
And everything else
The rest of the app.
Triggers, photos, progress, timing, the coach — all pointed at the same job.
Trigger intelligence
Matches what you log against what your skin did. Dairy might matter for you and mean nothing for your friend.
Findings you can act on
Not internet advice. A real pattern out of your own logs, with the size of the effect attached.
Weekly skin check
You take a guided photo in the same light every time, so your severity gets measured instead of guessed. Face and body.
Progress across cycles
This cycle against your last. The only comparison that means anything.
Your month at a glance
Clear days, mild days, flare days. The shape of your month gets obvious once you can see it.
The glow window
It works both ways. Cirra flags the days your skin peaks, so you can plan the event, the photos, the no-makeup day.
When to book treatments
Your skin is more sensitive and heals slower before your period, so Cirra flags your best and worst weeks for laser, waxing and peels.
A score you can check
You can see how often Cirra called your flare window right. Out in the open, so you know how much to trust it.
Shareable forecast card
Your daily forecast as a card worth screenshotting, and worth sending to the friend who'll recognize it instantly.
Your skin season recap
Clear days, worst week, biggest trigger, your type. Your whole season, summed up.
Made by people who've had the flare week.
No white coats, no pink femtech, no airbrushing. We don't smooth skin in our own photos, and we'll never tell you that you have a problem — just what's coming and what to do first.
First, find out how your skin actually moves.
Everyone's skin has a rhythm, and yours has a name — a starting point that describes when you flare, where it lands and what sets it off.
It's a starting point, not a box. From there Cirra keeps learning until the forecast is yours and nobody else's.
Two minutes. You get your type at the end.
Then it tells you what that means for you.
When you flare, where it shows up, and what's behind it. The shape of your month, written down. For a lot of people it's the first time anyone has explained the pattern you've been living with for years.
The part people screenshot.
How it works
Three steps, then it runs itself.
Set it up
Take a short quiz about your skin and connect your cycle from Apple Health, or just type in when your last period was. That is the whole setup.
See what is coming
Open the app and you get the week ahead for your face, back and chest, plus what to do about it and which day to start.
Do the one thing
Act before the flare instead of after it. Cirra then checks how your skin actually went and adjusts for next month.
The real cost
You've already spent hundreds on this.
Go look in your bathroom cabinet. You're not short on products. You're short on timing.
Not one of them knew what your skin was about to do.
So none of them could tell you when to start. Half of what you own probably works — you've just been using it at the wrong time, or piling five things on at once and hoping one of them sticks.

Five questions about your skin. The last one is your email, and nothing before it asks for anything personal.
Question 1 of 5
How old are you?
Before you ask
The obvious questions.
How is this different from a skin tracker?
A tracker is a record of the past. You photograph a breakout that already happened and watch a line move. Cirra works the other way: it uses your cycle to predict what your skin is going to do next, then gives you a dated action to stop it. One tells you what went wrong. The other gives you a shot at preventing it.
Is it only for acne?
No. Breakouts hurt the most, so that's probably what brought you here, but the same hormone cycle drives your oiliness, dryness, sensitivity, redness and the days your skin actually glows. Cirra forecasts all of it. Treating one without seeing the others is how you end up stripping skin that needed calming.
How much warning will I actually get?
It depends on your pattern. Flares usually land in a window before your period, but the timing is personal to you — you might see it a few days out, or closer to two weeks. Cirra learns your timing and tells you what it knows, plus how confident it is.
Is the advice really personal, or the same for everyone?
Personal, and it gets more so. Cirra weighs your cycle, your life stage, where you break out, what you already use, what you eat, how you train, how you sleep, and — most of all — what measurably worked for you last time. You and a friend with identical skin could get completely different plans, because yours is built from your own history instead of an average of strangers.
What can I ask the coach?
Anything you'd ask a friend who happened to be a dermatologist and had read your whole history. Why your chin is breaking out again. Whether to use an acid this week. What to start before Saturday. Whether a new product is purging you or breaking you out. It answers using your phase, your plan and your logged flares, not a generic article.
Does it work if my cycle is irregular?
Yes. Cirra doesn't need a textbook 28 days — it works from whatever your cycle actually does, tells you how confident it is each time, and gets sharper the longer you use it. Irregular cycles also come with more skin trouble, not less, so if that's you, this was built for you rather than around you.
What if I'm on the pill, or in perimenopause?
Yes to both, and it's one of the things Cirra is best at. It asks what stage you're at and tunes everything to it. On the pill, coming off it, postpartum, perimenopause — each one changes your pattern rather than removing it, so you get advice for the stage you're actually in instead of general advice written for somebody else.
Do I have to buy new products?
Usually not. Cirra tells you what a product needs to contain, like "2% salicylic acid, PM", and you can scan whatever is already on your shelf to see if it fits and whether this is the week to use it. Most of the time something you own already works — you were just using it on the wrong days. When you do want something new, scan it in the store or online first and Cirra will tell you whether it is worth buying for your skin.
Do you take money from skincare brands?
No. No brand deals, no affiliate links, no sponsored recommendations, nothing sneaky. Cirra never tells you which brand to buy, only what to look for on the label. Nobody is paying us to point you at their serum.
Is it a medical device?
No, and it doesn't diagnose or treat anything. When your pattern looks like a real problem — something severe, stubborn, or not what anyone assumed — Cirra helps you get ready for a doctor's appointment instead of trying to replace it.
What happens to my data?
It's yours. We don't sell it, we don't share it, and we don't hand it to advertisers. Photos stay private to your account, and you can delete everything whenever you want.
