The 4 cycle phases

A rhythm worth learning.

PeriodCode helps you understand the energy, mood, and support needs that usually come with each phase.
1

Menstrual

Days 1-5

Lower energy, cramps, and a stronger need for comfort are common here. Think warmth, patience, and fewer assumptions.

Phase 1 / 4
2

Follicular

Days 6-13

Energy often rises and things can feel lighter. A good window for plans, encouragement, and quality time together.

Phase 2 / 4
3

Ovulation

Days 14-16

Communication, confidence, and connection may peak. A strong time for dates, conversations, and being fully present.

Phase 3 / 4
4

Luteal

Days 17-28

Stress, sensitivity, and cravings can build here. A little more empathy, planning, and calm can go a long way.

Phase 4 / 4

Built around the app

What is actually inside.

The website now reflects what PeriodCode actually offers inside the Flutter app: nothing more, nothing oversold.

Daily Guidance

See the current phase, likely mood and energy levels, plus practical ideas for how to support her today.

Visual Timeline

Follow a clear cycle calendar with recorded periods, predicted days, and a simple overview of what is ahead.

Learn Mode

Go deeper with phase-by-phase explanations, symptoms, remedies, and communication tips that stay easy to understand.

Custom Reminders

Get a reminder before her period starts and add your own note so the support is thoughtful, not reactive.

Profiles and Pregnancy

Track more than one profile and switch into pregnancy mode for trimester-based guidance and week-by-week context.

Backup and Restore

Export your data, restore it later, and keep your setup portable without needing an account or cloud sync.

How it works

Simple to start. Practical every day.

Private from day one. No questionnaires, no onboarding marathon.
01

Add basic cycle info

Enter the last period start date and average cycle length. That is enough to unlock the core experience.

02

Check today and the timeline

Open the app to see today's phase, likely expectations, and a timeline view of what is coming next.

03

Support with confidence

Use the guidance, reminders, and learn mode to respond with empathy instead of guessing.

Privacy first

Yours. Only yours.

PeriodCode is built so the most personal data never leaves your phone unless you decide otherwise.

No account required

All data stays on your device. There is no mandatory sign-up before you can use the app.

No tracking. No ads.

PeriodCode is designed to be useful without feeling invasive. No ad-driven clutter and no tracking-first experience.

Backup on your terms
