## What is LineCheck?

LineCheck is your all-in-one pregnancy test tracker, LH/OPK ovulation tracker and TTC companion: test photos, cycle predictions, Apple Health, charts, comparisons, insights and reminders in one private app.

TRACK PREGNANCY TESTS
Scan or import pregnancy test photos. Review visible, faint or unclear lines, add notes and keep every test in your history. Use a free local scan, enter the result yourself, or let Luna's on-device AI read and explain the line.

TRACK LH & OVULATION TESTS (OPK)
Follow test-to-control ratios and low, rising, high or peak stages toward your LH surge. A Peak test can confirm ovulation and update your predictions.

PREGNANCY TRACKING
Follow your pregnancy week by week, with due-date estimates and growth updates. Keep appointments, visit notes and pregnancy photos together in one place. Use helpful tools like movement counting and contraction timing when you need them. You can switch to pregnancy mode during onboarding or any time from Home or Settings.

COMPARE TESTS SIDE BY SIDE
Compare pregnancy or ovulation tests to follow line progression and LH trends, or use AI Compare.

PREDICTIONS THAT LEARN FROM YOU
LineCheck estimates your fertile window, best testing days, ovulation, next period, cycle day and DPO from your own history and setup answers. Estimates widen honestly when cycles are irregular and update when a Peak test or temperature rise confirms ovulation.

WHAT YOUR BODY IS TELLING US
LineCheck watches your tests, daily logs and Apple Health data and tells you what it notices, like a temperature rise that backs up ovulation or short sleep that could delay it.

APPLE HEALTH, FREE FOR EVERYONE
Bring in periods, BBT, Apple Watch wrist temperature, cervical mucus, symptoms, sleep, heart rate, HRV, activity and weight. Temperature, weight and water you log are saved back to Health.

TRENDS & CHARTS
See line progression, OPK, BBT, cycle and period length, symptom and mood charts. With Pro, explore Cycle History, luteal phase, prediction accuracy, body rhythms, symptom timing and everything LineCheck has noticed.

AI PROGRESSION ANALYSIS
Select three or more saved tests and Luna explains the trend in plain language.

DOCTOR VISIT REPORT
Export a PDF of your charts, cycle history, symptoms and test progression to share with your doctor.

ENHANCE PHOTOS
Crop and adjust brightness, contrast, exposure, sharpness, greyscale and inversion to review faint lines. Adjustments do not change the physical result.

LOG BODY SIGNS
Log symptoms, moods, cervical mucus, BBT, weight, water, supplements, sex and insemination, in kilograms, pounds or stone.

ASK LUNA
Luna is your context-aware fertility assistant, using your tests, cycle timing, body signs and Apple Health data. Chat requires an internet connection.

WIDGETS & REMINDERS
Home Screen widgets show your countdown and today's plan. Set reminders for retesting, ovulation testing, fertile days or anything else.

Private iCloud sync, JSON export and in-app data deletion.
