03 — THE PRODUCT
Eighteen screens, each one answering a finding
Onboarding: eight screens to earn trust
The flow opens with the brand statement, then asks only what changes the product: how your period behaves (Regular / Irregular / No period — the mode decision from the research, asked as the second question), relevant conditions like PCOS or endometriosis, last period, duration, hormone therapy. Every step is skippable — “I don't know” and “prefer not to say” are real options, not dark-pattern fine print. And the final screen offers “continue without account” alongside sign-up — a quieter link below the card, but a genuine path into the app.
1 · HOW'S YOUR PERIOD?
2 · CONDITIONS
3 · LAST PERIOD
4 · DURATION
5 · HORMONE THERAPY

Home: one screen, five decisions — scroll to walk through them
Keep scrolling: the home screen stays put while each element lights up, with the finding it answers right beside it.
Start here
This is the home screen
Everything 37 people asked for, on a single screen — no tabs, no digging. Keep scrolling: each element lights up in turn, tagged with the finding it answers.
Step 1 / 5
FINDING A
The answer before the question
The very first pixel is the status pill — Day 4 · Menstrual, date underneath. No dashboard to parse, no tab to hunt: where you are in your cycle is already on screen the moment the app opens. And it's honest: the pill only appears once you've logged data and a pattern has formed — the app never fakes a prediction it can't back.
Step 3 / 5
FINDINGS C + F
The premium feature, free — and different for everyone
The hormone curves paid apps lock behind subscriptions sit here as a free Insights card. And this is where Finding F lands: for irregular cycles, no periods, hormone therapy and perimenopause the pattern runs in different modes — everyone reads their own cycle.
Step 5 / 5
FINDINGS C + D
Below the fold of attention
Blog and Meditate close the screen: reachable, never in the way. Articles on PCOS and cycle health, a player that breathes — no feed, no streak shaming, no engagement bait.
HOME — EVERY ELEMENT ANSWERS A FINDING
Step 2 / 5
FINDING B
Logging, one thumb away — twice
The Check-in card carries a progress bar — a deliberate choice: a half-filled bar creates the feeling of something almost complete, and that pull to finish nudges users to log more — every extra entry is exactly the data an accurate prediction needs. Fill the bar and the card celebrates you — “All logged ✦”. The same action repeats bottom-right as “Log today” and ＋, inside thumb reach.
Step 4 / 5
FINDINGS E + F
Advice that knows what day it is
The tip bar tints itself with the current phase and rewrites daily — rest and iron-rich food during menstruation, energy later. And the tips change with the mode too: no period or on hormone therapy, the guidance follows your situation. Never a verdict, never a guilt trip.
Logging that takes 30 seconds, not 30 taps
The check-in is five rows of pills — feel, blood, pain, craving, symptoms. Every option is one tap, thumb-sized (44 pt), no free text required. A date arc at the top swipes like a wheel; the selected day sits in a glass ring.
The Done button climbs from “Done” to “Superstar!” as you log — the only gamification in the app, and it costs nothing.
DAILY LOG
QUICK ADD + JOURNAL
A calendar that predicts without judging
The month view paints the predicted period as a soft coral band and tints the rest of the month by phase — follicular, ovulation, luteal. Logged days carry a tiny progress ring under the date.
What it never does: flag a late or irregular cycle as “abnormal.” That single pattern — the cycle regularity imperative — was the most documented anxiety in the research.
MONTHLY VIEW — PREDICTION AS A BAND, NOT A VERDICT
The premium feature, free on purpose
Hormone analytics is what paid apps lock behind subscriptions — and 30 of 37 people said they'd never pay. So the Pattern screen ships it free: four hormone curves across a 28-day loop, draggable, with the current day pinned.
Below it, “You're not alone” — anonymous one-line notes from others on the same cycle day. Community without profiles, feeds or follower counts.
CYCLE PATTERN — HORMONES + COMMUNITY
And when a 28-day curve isn't your reality — Finding F — home itself switches mode. Answer “Irregular” or “No period,” flag hormone therapy or perimenopause in onboarding, and instead of a pattern the app can't honestly draw, you get a screen built for your situation. These screens are also designed to make a quieter point: underneath the tracker, this is a journal — prediction may step back, but daily logging carries value for everyone.
IRREGULAR MODE — RHYTHM, NOT A 28-DAY CLOCK
HORMONE THERAPY MODE — MEDS-AWARE TRACKING
PERIMENOPAUSE MODE — NO REGULARITY JUDGEMENT
The content layer follows the same rule. Tips and the Blog are personalised too — both re-rank by the mode the app is in and the phase you're on: menstrual-phase rest advice for a regular cycle, trigger-focused reads for irregular ones, therapy-aware guidance on hormone therapy.
TIPS — PERSONALISED PER MODE + PHASE
BLOG — FEED FOLLOWS YOUR MODE
MEDITATE — LIVE DEMO · TAP READY
Stress sits at the top of the common cycle-disruptor list — Meditate is the rest moment built for it. The screen composes its visuals live, in tune with the music: each track paints its own palette and movement, and the whole field slows down as your session begins. The controls fade away after a few seconds and return with a tap — no feed, no streak, nothing to win. The third phone above is the real thing: tap Ready.
Settings that read like a receipt of the research
Cycle length and period duration as steppers, hormone-therapy as a first-class toggle that adds a Meds row to the daily log — and under About, one line that is the entire privacy policy: “All data stored locally on device.”
