Prepare gently
for your body's waves.
By linking your menstrual cycle with air pressure and weather, Well Rhythm helps you anticipate headaches and rough days before they arrive. A personalised daily message keeps you gently in step with your own rhythm.
That discomfort isn't just in your head.
When you can't quite name the reason, logging and lining things up reveals a pattern that's unmistakably yours.
Pressure-triggered headaches
When rain is on the way, your temples start to pound. Low-pressure days leave you feeling heavy and drained.
Pre-period mood swings
Irritability, sleepiness, skin changes — your mind and body can shift dramatically with your cycle.
Grey skies, low spirits
When overcast days drag on, your mood just can't seem to lift either.
Everything to support your rhythm.
Log. Notice. Prepare. Features crafted to gently accompany your everyday self-care.
Daily Message
A gentle, personalised message tailored to your cycle and the day's weather — brief enough to read on a busy morning.
"A little low-pressure today. Take it easy and keep warm."
Pressure & cycle × how you feel
Not just pressure — humidity, rain, sleep, water, and moon phase, overlaid with your records to show why today feels hard, all on your device. After about a week of data, your patterns start to emerge.
Calendar Logging
Log symptoms, basal temperature, and medication with a cherry-blossom phase display. Simple enough to keep up every day.
Partner Sharing
Share only a 'summary' — not detailed logs — via device-to-device E2E encryption. A gentle bridge between you and your partner.
Home Screen Widget
Check your daily message, pressure, and cycle phase at a glance — no need to open the app. Works on your lock screen too.
Apple Health / Google Health sync
Sync with Apple Health and Google Health to import basal body temperature and period records automatically. You can turn the connection off anytime, and your data stays only on your device.
* On Android, symptom sync is not available due to platform limitations.
Understand why today feels hard —
from your own data.
Not general theory — your own records hold the answer. Well Rhythm overlays pressure, humidity, rain, sleep, water, and moon phase with how you feel, computed entirely on your device. And we openly disclose the thinking behind it.

Even we can't read it.
Your health and cycle data is among the most sensitive information you hold. That's why Well Rhythm encrypts it on your device. Our servers never see the contents.
Read the full Privacy Policy → How it works →Encrypted on-device
Everything you log is encrypted on your phone. It is not designed to be stored wholesale in the cloud.
Servers see only a summary
Partner sharing sends only a 'summary', via E2E encryption between devices. Nothing is readable in transit.
Delete everything, anytime
Your data is yours. One tap wipes it all cleanly.
No tracking, ever
No behavioral tracking, ad trackers, or third-party analytics. We don't follow you around or build a profile of you.
Log. Connect. Prepare.
Log it
Tap to record your mood, symptoms, and cycle. Basal temperature and medication can be tracked too.
Connect the dots
Not just pressure — humidity, rain, sleep, water, and moon phase, overlaid with your records to show why today feels hard, all on your device. After about a week of data, your patterns start to emerge.
You can also see the "self-check" — hits and misses, nothing hidden.
Prepare with your daily message
Even on tough days, a gentle message helps you get a head start. That little mental prep makes all the difference.
Screens you'll actually want to open every day.
Select a screen from the menu to see what each one does and how it helps. The more you log, the more the display grows to reflect your own rhythm.
Screenshots Coming Soon
The actual screens (Home, Calendar, Pressure, Temperature, Correlation, Diary) will be revealed at the official launch. Stay tuned!
