Built for the years of being told it's “just stress.”
Endometriosis is common, and commonly dismissed. Linnea turns scattered, hard-to-remember days into a clear record, so you can understand your own patterns and be taken seriously.

Linnea exists so ten minutes with a specialist can finally count.
Log · in seconds
Logging that respects a hard day.
Flares don't wait for you to feel like filling in forms. Logging in Linnea is a few calm taps: a symptom, a 0–10 severity with words, done. Add detail only if you want to.
-
Your symptoms, one tap each. Pelvic pain, fatigue, bloating / endo belly, nausea and more, rated on a big, readable 0–10 scale.
-
The whole picture. Cycle and flow, medications and gentle reminders, food triggers, sleep, stress and mood, all logged the same calm way.
-
Made for flare days. Big targets, one-handed reach, no time pressure, and a note only when you have something to say.
-
No streaks. No guilt. Miss a day or a month: nothing nags, nothing breaks, nothing shames you back.
Patterns · on your phone, not a server
See what lines up, in your own words.
After a couple of weeks, Linnea quietly looks across what you've logged and surfaces the associations worth a conversation, analysed entirely on your device.
-
Patterns, not verdicts. How symptoms line up with sleep, stress, foods, or your cycle, always framed as something to explore with your doctor, never a diagnosis.
-
Honest math. A pattern only surfaces when there's enough data behind it. If the signal is thin, Linnea says nothing. No drama, no false alarms.
-
Trends you can actually read. Weekly severity, cycle-phase views, and how things looked before and after a medication change.
The doctor report · the whole point
Walk in with evidence.
One tap turns your recent weeks into a clean, clinician-friendly PDF: severity over time, medications, top triggers, and the patterns worth discussing. The difference between “I just feel off” and here's exactly what's been happening.
-
Appointment-ready. Organised for a short consult, so the conversation starts with evidence, not recall.
-
Built on your device. The report is generated on your phone. Nothing is uploaded. You choose what's shared, and with whom.
-
Free. Always. The report is the reason Linnea exists. It will never sit behind the paywall.
Designed for 2 a.m.
Easy on tired eyes.
A warm, true dark mode (not clinical grey) for the nights a flare does the scheduling. Big targets, one-handed reach, and language that stays calm when you can't.
- Warm dark mode, end to end
- One-handed, big-target logging
- Optional biometric app lock
Private by design
Your body. Your data. Your phone.
Most period and health apps quietly monetise intimate data. Linnea was built so your health record never has to leave your device: a promise you can check, not just trust.
Encrypted on your device
Everything you log lives in an encrypted database on your phone, excluded from cloud backups.
No account, ever
No sign-up, no email, no password. Open the app and it's yours. We couldn't identify you if we tried.
No ads. No analytics.
Zero advertising or tracking SDKs, audited dependency by dependency. Not in the app, not on this site.
Nothing uploaded
The app makes no network requests in normal use. We can't read your data. We never have it.
Export any time
A complete JSON export of everything, delivered through your phone's share sheet. Your data is portable.
Delete means delete
One action erases the database and its key from your device. There's no server copy. Deletion is final.
Read the full privacy policy: it's short, because there's nothing to hide.
Fair, and honest about it
The core of Linnea is free. On purpose.
Being believed shouldn't cost money. Logging, your patterns, and the doctor report are free forever. Premium adds depth for those who want it.

Can't afford it? Then it's yours.
Tap “I can't afford this” on the app's paywall or email [email protected] and we'll switch Premium on. No questions, no proof, no guilt.
Prices in USD. Both stores localise to your region, adjusted for purchasing power. Subscriptions are billed by the App Store / Google Play and can be cancelled there in two taps.
Questions, answered plainly.
Where does my data actually live?
On your phone, in an encrypted database (SQLCipher) whose key sits in your device's secure hardware. It's excluded from iCloud/Google backups, and the app makes no network requests in normal use. There is no account and no server copy. See the privacy policy.
Is Linnea medical advice?
No. Linnea is a general-wellness app, not a medical device, and not medical advice. It helps you notice and share patterns in what you logged; your clinician interprets them. Insights are always framed as patterns to discuss, never a diagnosis or prediction.
What's free, and what's Premium?
Free, forever: logging (symptoms, cycle, medications, triggers, check-ins), surfaced patterns, 8-week trends, and the doctor report as a PDF. Premium ($39.99/year after a 7-day trial, $7.99/month, or $119.99 lifetime) adds longer-range patterns, 26-week trends, unlimited history, richer reports, and CSV export. And if you can't afford it, we'll give it to you: email [email protected].
Which platforms does it run on?
iPhone and Android phones. Linnea is launching on both stores now. The download badges above go live the moment the listings do.
Can I take my data with me, or erase it?
Both, any time. Settings → Privacy & data gives you a complete JSON export through the share sheet, and “Delete all data” permanently erases the database and its encryption key from your device. Deletion is immediate and final. There's nothing anywhere else to delete.
Will there be backup or sync across devices?
It's planned: optional, end-to-end-encrypted sync where the server only ever sees ciphertext, so even we can't read it. It will be strictly opt-in, with the privacy policy and store labels updated before it ships.
Who makes Linnea?
A tiny independent studio, T ELS PROG (PTY) LTD, that believes health apps shouldn't harvest the people they serve. No ad-tech, no data brokers, no growth hacks. Questions or ideas: [email protected].
