Lunear supports five languages: English, Español, Français, Português and Deutsch, making the experience accessible to a broad international audience.
What Is Lunear Period & Cycle Tracker?
Lunear is built around five main areas: Today, Calendar, Lunear Assistant, Insights and Settings. The Today view is designed as an at-a-glance dashboard for the current cycle, while the Calendar provides a visual monthly view of logged and estimated cycle phases. The product is intended to be more than a simple period calendar. Its four tracking modes Regular Tracking, Trying to Conceive, Pregnancy and Perimenopause let the experience change as a user’s goals and reproductive stage change.
Regular Period and Menstrual Cycle Tracking
In Regular Tracking mode, users can follow their current cycle day and phase, see an estimated next period, review an estimated fertile window and see an estimated ovulation date. The circular cycle display provides a quick visual representation of progress through the cycle. Users can also adjust typical cycle length and average period length in Settings.
Tracking Irregular Cycles
Lunear includes an irregular-cycle option for users whose cycle length varies from month to month. Instead of forcing a single fixed average, users can enter their shortest and longest recent cycle lengths. The prototype is designed to present a range for the next-period estimate and approximate fertility timing when irregular-cycle tracking is enabled, which is more transparent than displaying a single apparently exact date.
Trying to Conceive (TTC) Mode
TTC Mode emphasizes the estimated fertile window and ovulation day. Users can also enable fertile-window alerts and choose reminder timing. Fertile-window and ovulation dates are estimates generated from cycle information and should not be treated as confirmation of ovulation, fertility testing or contraception.
Pregnancy Tracking Mode
Pregnancy Mode changes the standard cycle presentation into a pregnancy-focused view. Users can enter how many weeks pregnant they are, after which Lunear displays the current pregnancy week, trimester, estimated due date and progress toward 40 weeks. This design allows a user to move from TTC-oriented tracking into pregnancy tracking without leaving the same product.
Perimenopause Mode Explained
Perimenopause is the transitional stage leading up to menopause, during which menstrual cycles and symptoms may become more variable. Lunear includes a dedicated Perimenopause Mode for this stage. The mode is designed around looser predictions and additional symptom-focused tracking, reflecting the fact that cycle timing may become less predictable during perimenopause.
Detailed Daily Logging
Users can record menstrual flow as none, light, medium or heavy; select multiple symptoms; choose a mood; and add a personal note of up to 150 characters. The prototype includes symptom choices such as cramps, headache, bloating, fatigue, acne, backache, nausea and tenderness. These daily entries can later be reviewed in History and summarized in Insights.
Cycle Calendar and History
The Calendar visually distinguishes logged period days, predicted period days, fertile days, estimated ovulation and days containing logged information. Users can tap dates to view an entry or add one. The History area presents logged days in reverse chronological order, including flow, symptoms, mood and notes, creating a reusable record rather than a collection of disconnected entries.
Insights and Pattern Tracking
The Insights section can show average cycle length, average period length, recent cycle lengths and frequently logged symptoms. When there is not enough history, Lunear indicates that additional period dates need to be logged before stronger cycle statistics can be calculated. Premium adds AI-personalized insights that can summarize cycle-length trends, commonly logged symptoms and mood patterns in plain language.
Ask Lunear: AI Cycle Assistant
Ask Lunear provides a conversational interface for questions about the cycle, symptoms, mood and related tracking context. The prototype is designed to answer with awareness of the current cycle day and phase when cycle data is available. The current product flow provides three free assistant chats, with unlimited conversations included in Premium.
Privacy and Private Mode
Lunear offers Guest Mode for starting without an account. Private Mode includes app lock, hidden notification content and discreet app-icon options. These features are designed to reduce the amount of sensitive cycle information visible to other people using or viewing the device. The prototype also presents local-first storage by default, with optional encrypted cloud backup for eligible account and Premium flows. Users should review the production app’s latest privacy policy and Google Play Data Safety information before enabling backup or other connected features.
Doctor Report PDF Export
Premium users can generate a printable Doctor Report covering a selected period such as the last three months, last six months or all available history. The report can include cycle summary information, logged days, flow, symptoms, mood, notes and symptom frequency. The report is intended to organize user-recorded information for appointments. It is not a medical diagnosis.
