What does the setup ask, and do I have to answer everything?

Step 1: About you

• Profile picture: optional.

• Name: 2 to 50 characters.

• Username: 3 to 30 characters, lowercase letters, numbers and underscores. It's how friends find you, so it has to be unique.

• Creator code (optional): if someone introduced you to Cyclea.

Step 2: About your cycle

• First day of last period: the day your most recent period started.

• How many days?: how long that period lasted, from 1 to 10 days. If it started in the last few days and hasn't ended yet, choose Still going.

Cyclea logs flow on each of those days, so your Planner and forecast start from your real period. With Still going, it logs every day up to today, and My Day asks Still on your period? on the next days until it's over.

Cyclea doesn't ask for your usual period or cycle length. Your answer becomes your period length, and your cycle starts at 28 days. While your cycle prediction is Automatic, both then follow the periods you log.

Not sure? Answer I don't know yet for the date or I don't know for the days. Cyclea then starts with a 5-day period and learns from what you log.

If you stop halfway, you'll continue where you left off next time you open the app. You can change your name, username and cycle settings later on the Profile tab.
