Insync is a fitness app designed to help women align training with their menstrual cycle, recovery and changing energy levels. Rather than treating every day alike, it uses cycle and performance information to offer a personalized recommendation for what to do and how intensely to train. Members can connect a wearable or log their cycle, and the app maps hormonal phases into an individual performance calendar. Each morning, Insync provides a clear training decision based on cycle phase, recovery and recent output, with guidance intended to support both exercise and rest.

The app organizes its approach around four cycle phases: menstrual, follicular, ovulatory and luteal. Recommendations range from active recovery and mobility to strength-building, higher-intensity efforts, and moderated training with attention to sleep, fueling and technique. Insync presents its recommendations as female-first and informed by medical expertise, translating data into practical direction rather than simply displaying charts. The service is currently preparing for launch and inviting users to join its waitlist for early access.
