Ovalune
Ovulation & LH tracker
Trying for a baby? Photograph your LH ovulation test and get a clear read of the two lines, then see your fertile days and estimated ovulation on one calendar. Period tracking included, free and with no account. With Ovalune Plus, a doctor answers your questions every week.
Android. iPhone version in preparation.
Two lines, one answer.
LH test reader
Photograph your ovulation test strip. Ovalune finds the T and C lines, reads the T/C ratio and shows an estimate: negative, rising or likely peak. Free.
Fertile window & ovulation
Your likely fertile days and estimated ovulation, marked on the calendar and refined by your LH tests, cycles and symptoms.
Every LH test, side by side
Compare your strips day by day and see your LH curve rise towards the peak across the cycle.
Period tracker
Log periods, flow, mood and symptoms in a few taps. Next period and cycle length predicted from your own history.
A coach for your cycle
A short daily check-in, tips based on your notes and a journey from fertile window to test day.
Talk to a doctor
With Ovalune Plus, a doctor answers your questions about your cycle, ovulation and tests: 1 free appointment every week, booked in a few taps once your trial has ended.
Private by design
