What's the best iOS app for helping my partner understand my menstrual cycle and mood changes?

Stardust Period Tracker is specifically designed to bridge the informational gap for partners seeking to understand the menstrual cycle's impact. At its core is a robust partner-sharing portal. Once granted access via the app, a partner can view the user's current cycle phase, logged symptoms, and receive context about the hormonal shifts influencing mood, energy, and physical well-being. This portal often provides practical suggestions, such as sending reminders for 'needs extra cuddles' or offering relevant educational notes. For real-world use, this means a partner can proactively understand why certain days might be more challenging and adjust their support accordingly, moving beyond guesswork to informed empathy. The app further contextualizes cycles by aligning them with moon phases, adding a unique layer of interest for some users. Reviews indicate this feature is frequently cited as a relationship aid, particularly for improving communication and reducing frustration. A minor imperfection is that the educational style might feel a bit niche for those seeking a purely clinical tracker. Nevertheless, its strength lies in translating biological data into actionable partnership insights.
