Period Tracker - CycleBond

CycleBond is free for women and includes private cycle tracking, period days, fertile days, and personal insights.
Partner features for men require a one-time in-app purchase, CycleBond PRO.

Track your cycle with clarity, privacy, and ease. See your period, fertile days, ovulation, and cycle phases in one simple view. Get gentle daily insights, plan ahead with more confidence, and stay in sync with your body.

And when you want, you can share your cycle with your partner — so he can better understand what phase you are in, how you may be feeling, and how to respond with more care, patience, and empathy.

Privacy and security come first

Your cycle is personal — and it should stay that way.

CycleBond is designed with privacy in mind:
• No unnecessary personal data
• No account required for core use
• No name, no email address, no password needed
• Your cycle settings stay simple and private
• A safe and thoughtful space for your most personal information

We believe cycle tracking should feel calm, secure, and respectful — never intrusive.

Designed for women

CycleBond helps you understand your rhythm without making things complicated.

Use the app to:
• Track your cycle length
• Set your period days
• See fertile days and ovulation
• Choose your period start date
• View your current cycle phase
• See weekly and monthly cycle previews
• Get gentle daily insights based on your phase
• Plan your month with more clarity

Whether you want to understand your mood, energy, timing, or body better, CycleBond helps you feel more connected to yourself.

Built for couples too

CycleBond is more than a cycle tracker — it can also help create better understanding in a relationship.

With partner sharing, your partner can follow your cycle in a respectful and supportive way. This can help him:
• understand your current phase better
• know when you may need more comfort or more space
• respond with more empathy
• better understand emotional and physical changes
• avoid unnecessary misunderstandings
• feel more connected to what you are experiencing

Instead of guessing, he gets a clearer view of your rhythm — so support feels more natural, and connection feels easier.

Helpful daily guidance

CycleBond offers more than dates on a calendar.

Depending on the phase, the app can help surface gentle insights about:
• how you may feel
• what may support you most
• what to be mindful of
• how energy and emotions may shift through the cycle

For partners, the app can also provide supportive guidance such as:
• how she may feel
• what helps most
• what to avoid

This makes the experience more practical, more human, and more useful in everyday life.

A calm and beautiful experience

CycleBond is designed to feel soft, modern, and easy to use:
• clean cycle ring
• weekly and monthly calendar views
• elegant daily cards
• simple setup
• beautiful, feminine design
• support for multiple languages

Everything is built to make cycle tracking feel less overwhelming and more natural.

Why CycleBond?

Because understanding the cycle can change more than just planning.

It can help women feel more in tune with their body.
It can help men become more supportive and aware.
And it can help couples communicate with more empathy and less confusion.

CycleBond helps turn cycle tracking into self-understanding — and shared understanding.
