About
About LineCheck.
Luna Check uses LineCheck’s own trained AI models on your iPhone, iPhone Duo, iPad or Android phone to read hCG pregnancy and LH ovulation tests. It checks visible test and control lines and reviews LH line ratios entirely on your device, without uploading your test photos to a server. Rechecks also run on-device. Save your test photos, compare faint lines side by side and follow changes over time. Cycle tracking, calendars and pregnancy tools keep the rest of your journey together. LineCheck is free to download, with an optional Pro upgrade. LineCheck is not a medical device and does not diagnose pregnancy, fertility status or health conditions; follow your test instructions and consult a healthcare professional when needed.
