Lua is a period tracker and contraceptive reminder in one. Designed around a simple idea: your cycle data belongs to you, and only you. YOUR CYCLE, CLEARLY Log your period in seconds and Lua answers the questions that matter, in plain words: What phase am I in? When is my next period? When is my fertile window? No chart-reading required — the answers come first, the charts are there when you want them. - Period predictions based on your own cycle history - Fertile window and ovulation estimates - Cycle phase, always visible at a glance - Symptom and flow logging TRYING TO CONCEIVE If you are trying to conceive, Lua estimates a fertile window from the period starts you logged. It is a span of days, not a date, with the help of confidence metrics like mucus test, basal temperature, etc. If you are already pregnant, the same app can keep week by week on the phone. NEVER MISS YOUR CONTRACEPTIVE Lua supports the method you actually use. Not just the pill: - Pill: daily reminders that fit your pack schedule - Ring: insertion and removal reminders - Patch: weekly change reminders - Shot: injection appointment reminders - IUD & implant: replacement date tracking Each method has its own tailored schedule and logic. Reminders are quiet, respectful notifications at a time you choose. INSIGHTS THAT MAKE SENSE Lua turns your data into short, readable insights about your cycle. Computed on your device, phrased for humans, never sensationalized. WORKS WITH APPLE HEALTH Lua can read your existing cycle history from Apple Health so predictions are useful from day one, and write your logged cycle data back. You choose exactly what to share, permission by permission. PRIVATE BY DESIGN Most period apps send your data to their servers. Lua doesn't have servers. - All data is stored locally on your device - No account, no sign-up, no email required - No ads, no third-party analytics, no data selling, ever!
