Cync grew from that question into a daily planning tool for anyone who wants practical guidance for a changing cycle.
Drag through a cycle and watch the plan move with it. Phase sets the context. Your daily check-in shapes the details.
Based on your recent cycles, day 22 has often felt more difficult. Consider an earlier bedtime tonight and lower-impact movement tomorrow.
psst, try day 22
Phase gives context. Your check-in shapes the plan.
This is an example. Your real recommendations are personalized to your own inputs and may differ from general phase guidance.
Period trackers tell you where you are. Wearables show how your body is responding. Cync brings cycle context and today's check-in together to help you decide what to do next.

I spent a year building the thing I wish I'd had. After my cycle-syncing content reached tens of millions of views, thousands of women shared the same frustration: they could track their cycles, but no one helped them decide what to do with that information. Cync is the answer we couldn't find.

Connect lab results through Apple Health, or add a photo or PDF, to view markers like thyroid, iron, vitamin D, estrogen, and progesterone next to where you are in your cycle. Cync keeps your records in one place, so your conversations with your provider are better informed. It doesn't diagnose or interpret your results.
Explore the core experience at no cost. Premium unlocks deeper trends, more personalized content, expanded Ask Cync access, and daily workouts.

For years, women of childbearing potential were routinely excluded from early clinical research. As a result, many health and wellness baselines were built with less information about cycling bodies.
Cync does not assume every woman feels the same in every phase. It combines cycle context with your own check-ins, symptoms, goals, and connected data to make everyday guidance more personal.
Your cycle is context. Your experience is the signal.
No. Life after birth control is where Cync began, but the app is designed for women who want to understand their cycles, symptoms, energy, and wellness patterns more clearly.
No. Cycles vary, and Cync does not assume every cycle lasts 28 days. You can log your own dates and daily experience. Phase estimates may be less precise while a cycle is irregular or changing.
Yes. You can still log symptoms, complete check-ins, and use Cync's wellness tools. Some phase-based guidance may be less relevant depending on your method and whether you experience a natural cycle.
No. A wearable is optional. Cync can use the information you enter during check-ins, and Apple Health can add more context when you choose to connect it.
