Help, without the hold music.
Short, straight answers about the app, Doctor Chat, billing and your data.
Getting started
Lena is a women’s health app with clinical-grade AI that learns your cycle, symptoms and history. Through Doctor Chat, a real doctor is one tap away.
Yes, and more. Lena tracks your period and cycle, predicts your next period and ovulation, and logs symptoms, energy, sleep and mood. Ask Lena anything, and reach a real doctor with Doctor Chat.
LenaCare, a company registered in Paris. Its co-founders are Julie Gauthier (CEO), Prof. Arash Rafii (professor of obstetrics and gynecology) and Fekry Aiad (CTO).
iPhone on iOS 16.4 or later, and Android phones on Android 8.0 or later.
On the App Store and Google Play, free to download. Our download page links straight to both.
With your Apple or Google account, so there’s no new password to remember. iPhone offers both; Android uses Google.
English, French, Arabic, Spanish and Portuguese. Lena starts in your phone’s language; to switch, open Settings, then App language.
Yes. Lena is for people aged 16 and over.
Using Lena
Anything about your cycle, symptoms, sleep, food or mood. Lena answers from your own history, and you can add a photo or a file. It informs and supports; it doesn’t diagnose.
A quick log of how today feels: energy, sleep, stress and symptoms. Lena folds it into today’s guidance. You can also just tell Lena in the chat, and it gets logged.
Log your period, and Lena maps each cycle day to its phase, predicts your next period and ovulation, and colours your calendar. Predictions are estimates, not contraception.
Lena still works. For an irregular cycle, open Settings, then Period tracking, and turn on Irregular cycle. No periods right now? Check-ins work without any cycle tracking.
A weekly report and a monthly cycle report, written for you: your stats, your energy, what Lena noticed and what to try next. You can share any report as a PDF.
Yes. In Settings, open Reminders to set your check-in time and switch the check-in reminder, phase updates and period alerts on or off.
Doctor Chat
How Doctor Chat worksA private chat with a real doctor, right inside Lena. Your doctor sees your cycle and symptoms, so you don’t start from zero. Only you and your doctor can read the conversation.
In the chat, switch from Lena to Doctor Chat. Got an invite code from your healthcare provider? Tap I have an invite code for instant access.
It’s included in Lena’s free trial, with no card and no commitment. After that, it comes with Premium, or with an invite code from your healthcare provider.
Typically within 15 minutes. With notifications on, you’ll know as soon as your doctor replies.
No. If it’s urgent, call your local emergency number right away.
Subscription & billing
Yes. It’s free to download and free to start, no card needed. New accounts also get a free trial with everything unlocked.
Cycle tracking, check-ins, reports and the content library are free. Premium adds unlimited chat with Lena, and Doctor Chat.
If you subscribe, you pay through the App Store or Google Play, and the app shows the price before you confirm. We never see your card details.
Through your store, not in Lena: your Apple Account’s subscription settings on iPhone, or your Google Play subscriptions on Android. Turn off renewal at least 24 hours before the period ends. Deleting the app doesn’t cancel it.
Refunds go through Apple or Google, under their own policies. Ask the store you paid through.
Nothing to cancel. The trial needs no card and never turns into a paid plan by itself. It ends on the date shown in the app, and your data and the free features stay.
Privacy & data
On servers in the EU, under GDPR. That covers your account, health data, chats and files.
You, and a doctor only if you start a Doctor Chat with them. Lena’s AI processes what it needs to answer you. We never sell your data: not to advertisers, insurers, employers or data brokers.
Large language models, guided by your own context: your cycle, check-ins and history. Our privacy policy has the details.
Only if you connect it. Lena reads data like your cycle, sleep, activity and heart rate, never writes anything back, and you can switch it off anytime in your phone’s settings.
In Settings, tap Delete account and confirm. It’s immediate and can’t be undone; backups clear within 90 days. Can’t open the app? Use our account deletion page.
Any report can be shared as a PDF, right from the report. For a copy of everything we hold about you, email privacy@lenacare.ai; we reply within one month.
Still stuck?
Email contact@lenacare.ai, or write to us through our contact form.
You probably used a different account. Sign in with the same Apple or Google account as before: Lena matches accounts by email, so a different address, like one from Apple’s Hide My Email, starts a new account.
Open Settings, tap Report a bug and tell us what went wrong. Or email contact@lenacare.ai.
We’d love that. Open Settings and tap Send feedback. We read every one.
