LineCheck is your all-in-one pregnancy test tracker, LH/OPK ovulation tracker, and TTC companion. Test photos, cycle timing, BBT, charts, comparisons, insights, and reminders in one private fertility tracker.
TRACK PREGNANCY TESTS
Scan or import home pregnancy test photos. Review visible, faint, or unclear lines, add notes, and organise every test in your history.
Choose a free local scan, enter the result yourself, or let Luna's on-device AI model read and explain the line.
TRACK LH & OVULATION TESTS (OPK)
Review LH strips, follow test-to-control ratios, and track low, rising, high, or peak fertility stages toward your LH surge.
COMPARE TESTS SIDE BY SIDE
Compare pregnancy or ovulation tests to follow line progression and LH trends. Save comparisons, use AI Compare, and revisit results in History and Calendar.
TRENDS, CHARTS & INSIGHTS
Explore Pregnancy Line Progression, OPK, BBT, cycle-length, symptom, and mood charts. See plain-language insights based on your saved tests, cycle timing, and body signs.
AI PROGRESSION ANALYSIS
Select three or more saved pregnancy or ovulation tests and let Luna analyse the sequence chronologically, explaining the trend in plain language.
PDF EXPORT
Export a fertility report with charts, summaries, cycle signals, symptoms, moods, and progression data to keep or share with your doctor.
ENHANCE & REVIEW PHOTOS
Crop photos and adjust brightness, contrast, exposure, sharpness, greyscale, and inversion to review faint lines more clearly. Adjustments do not change the physical result.
UNDERSTAND YOUR CYCLE
Log periods, cycle details, or a known ovulation date. LineCheck estimates your fertile window, best testing days, predicted ovulation, next period, cycle day, and DPO.
LOG BODY SIGNS
Log symptoms, moods, cervical mucus and position, supplements, sex, and insemination alongside your cycle timeline.
SYNC WITH APPLE HEALTH
Import BBT, Apple Watch wrist temperature, period flow, cervical mucus, and test results from Apple Health. Read-only — your data stays in your control.
SET REMINDERS
Create reminders for pregnancy retesting, ovulation testing, fertile-window timing, or anything else.
ASK LUNA
Luna is your context-aware fertility assistant, using saved tests, cycle timing, charts, body signs, and reminders to help you plan and understand.
