Private by design
Local only. No cloud. Ever.
PeriWise has no servers for your health data, no accounts and no login. Every symptom you log is stored only on your iPhone, inside an AES-256 encrypted database whose key never leaves your device's Keychain.
We didn't just promise not to look at your data — we built the app so that we can't. There are no network calls involving your health data, no analytics SDKs and no crash reporters that phone home.
What PeriWise does
Small daily check-ins, clear personal insight
Everything below runs entirely on your iPhone — even with Airplane Mode on.
Track your cycle
Period days on the calendar and a gentle estimate of when the next may start — built for the irregular cycles of perimenopause.
Medication & supplements
Keep a list of what you take, with reminders scheduled entirely on your device.
Note your measurements
Weight, blood pressure, blood sugar — recorded in seconds and charted over time.
See your patterns
Trends across symptoms, sleep, mood and cycle. The last 7 days are free; the full 30- and 90-day picture comes with Premium.
Premium
Cycle-aware insights
Patterns, triggers and cycle effects, computed entirely on your phone — never advice, never a diagnosis, never sent anywhere.
Premium
Bring in your wearable
Import sleep and heart data from Apple Health or your Oura Ring — data flows onto your iPhone, never off it.
Doctor-ready PDF reports
Turn your logs, cycle and measurements into a clean, printable summary for appointments. You choose what to share.
Always free
Made for everyday life
Log from your Apple Watch or the lock screen, arrange home-screen widgets, lock the app with Face ID, and export or import everything when you change phones.
A look inside
Calm by design, from the first tap
PeriWise is not a medical device
PeriWise is a self-observation journal. It does not diagnose, treat, cure or prevent any disease or condition, and it does not provide medical advice. The insights it shows are simple, rule-based observations of the data you entered — nothing more. Always consult a qualified healthcare professional about symptoms, treatment and health decisions.
Perimenopausal cycles are irregular by nature, so the cycle estimate is for orientation only — it is not a contraceptive method and must not be used to prevent or plan a pregnancy.
Logging is free. Understanding is €1.49.
Downloading PeriWise, logging your days, tracking your cycle and creating doctor reports is free — your record is only useful if it's complete, so writing it down never sits behind a paywall. One small subscription (€1.49/month, cancel anytime in your Apple settings) unlocks the analysis on top: personal insights, the 30- and 90-day trend views, and cycle-aware analysis of imported wearable data. No other tiers, no ads, no upsells.
