Frequently asked questions
The things people ask us most.
What can Lua track in one app?
Lua is built so you do not need a separate period app, pill reminder, sex log, or pregnancy tracker. In one private home you can track your cycle, contraception (pill, ring, patch, shot, IUD or implant), intimacy, and pregnancy week by week, including kicks and contractions when you need them.
Is everything still private if I use more than one feature?
Yes. Every feature writes to the same on-device storage. There is no Lua server and no account, so cycle logs, contraception schedules, sex entries, and pregnancy notes never leave your phone. Turning on more features does not change that.
Do I need a different app when my goals change?
No. Lua is meant to move with you. You can track while avoiding pregnancy, turn on Trying to Conceive mode for fertile-window estimates, then switch into pregnancy mode when that chapter starts. Your past logs stay with you. You do not have to start over in a new app.
Does Lua work offline, and do I need an account?
Yes to offline, no to an account. Lua has no backend to sign into. You open it and start using it, even in airplane mode. Reminders are scheduled on your phone, so they still work without internet.
