Sync is a free hormone health app created by Samāh. It helps women and men understand their hormones, track their cycles or daily rhythms, and make small lifestyle changes that actually support balance, not quick fixes.

No. Sync is built for everyone. Women can track their menstrual cycles and phases, and men can log energy, focus, and mood based on their 24-hour hormonal rhythm.

Most tracking apps stop at logging data. Sync explains what your hormones are doing and why you might feel a certain way. It is also completely free, has no ads, and does not promote or sell products inside the app.

It means Sync is free to download and use. We plan to keep it free for as long as we can. We believe hormone education should be accessible to everyone, not hidden behind a paywall.

You can log: Periods and cycle length, PMS symptoms, Energy levels, Mood, Sleep and cravings. The app then gives insights for each phase and helps you understand how to support your hormones through food, rest, and simple rituals.

Men can log daily energy and focus, stress and sleep quality, mood and motivation. Sync helps you align your day with your body’s natural testosterone and cortisol rhythm for better performance and recovery.

Yes, but ideally with parental guidance. The app is safe, educational, and made to create awareness, not fear. It is a great way for teens to start learning about their bodies.

You will need the internet to download updates and read articles, but most logging and tracking features work even offline.

As often as you want. Most people log once a day or a few times a week. The more you log, the more accurate your insights become.

Sync was created by Keerthi, founder of Samāh. After her own experience with hormone imbalance, she wanted to build something free, trustworthy, and science-based for everyone.

No ads, ever. All features are free right now.

Sync 2.0 is in development. It will include Pregnancy, PCOS, and Menopause Modes, and a 90-Day Sperm Health Challenge for men. You will get an in-app update once it is ready.

Yes. Sync works globally. It is designed for both Indian and international users.

Our goal is to create a global movement for hormone health and awareness. We are adding community support, expert interviews, and new modes in the coming months.

Yes, you can. Some people experience bleeding more than once a month and Sync allows you to log those as separate cycles. However, your phase predictions will change based on these entries. The app’s accuracy depends on consistent tracking since it is based on general phase-based evidence.

The first period date you enter when installing the app will remain fixed, so please make sure to add it accurately. For the following months, you can update your period dates anytime by using the Log Period button, selecting Clear, and then re-entering your new period start date.
