LineCheck brings your pregnancy tests, ovulation (LH/OPK) tests, cycle data and notes into one app. Photograph your tests, see estimates, compare results and follow your trends.
PREGNANCY TESTS
Photograph or import a test to look at visible, faint or hard-to-read lines. Save the result with notes so you can come back to it. Use the free on-device reading, enter the result yourself, or ask Luna's AI to describe the line.
OVULATION TESTS
Follow LH tests and the ratio between the test line and the control line. See low, rising, high or peak readings and how they change across your cycle. A peak result can adjust your ovulation estimate.
PREGNANCY TRACKING
See your week of pregnancy, estimated due date and your baby's development. Keep appointments, questions, visit notes and photos in one place. Use the kick counter or contraction timer when you need them. Turn on pregnancy mode during setup or later from Home or Settings.
COMPARE YOUR TESTS
Put pregnancy or ovulation tests side by side to see how the lines and LH trends change. AI-assisted comparison is also available.
ESTIMATES FOR YOUR CYCLE
From your history and answers, LineCheck estimates your fertile window, good days to test, ovulation, next period, cycle day and days past ovulation (DPO). With irregular cycles the estimates show a wider range, and they update as you add data.
TRENDS AND REMINDERS
See your trends in charts and set reminders for tests and your cycle. Log symptoms, mood, cervical mucus, temperature, weight, water and more.
LUNA
Ask Luna questions about your results, cycle or pregnancy. Luna chat and Luna's "Look again" check send what's needed to answer to LineCheck's servers; other readings happen on your phone.
PRIVACY
Your test photos and history are stored on your device. If you choose Luna AI checks, chat or AI comparisons, the data needed to answer is sent to LineCheck's servers. Android backups depend on your device settings. See our privacy policy for details.
IMPORTANT
LineCheck is not a medical device and does not diagnose pregnancy, infertility, ovulation or any medical condition. Results are for reference only. Follow your test instructions and talk to a doctor before making medical decisions.
LineCheck is free to use with ads. LineCheck Pro removes ads and unlocks more features through a subscription billed by Google Play.
