HerWeigh is a cycle-aware weight tracking app designed specifically for women on iPhone and iPad. Instead of treating every daily scale number the same, HerWeigh overlays your weigh-ins directly with your menstrual cycle phases, giving you hormonal context for what you see on the scale. WHY HERWEIGH? Real body tissue (fat or muscle) changes slowly—typically at a maximum rate of roughly 0.1–0.3 lbs per day. When your scale jumps or drops by 2–5 lbs across 3–4 days, it is almost entirely hormonal fluid and glycogen shifts triggered by progesterone, estrogen, and aldosterone. HerWeigh helps you separate temporary water swings from real body composition progress so you never panic, restrict, or stress over the scale again. KEY FEATURES: • Interactive Cycle-Aware Tracking: View and scrub through your daily weigh-ins mapped alongside your Menstrual, Follicular, Ovulation, and Luteal phases. • Water Retention & Water Drop Insights: Automatically detect rapid fluid swings (like late-luteal retention or period water drops) and tap multi-day streaks to highlight them directly on your chart. • Personalized Hormonal Baselines: View your typical weight range and cycle average projected from previous cycles to know what is normal for your unique body. • Cycle-to-Cycle Trends: Filter out monthly water noise with cycle comparison and cycle-to-cycle change charts to track true long-term fat loss or muscle gains. • Sleep, Energy, Mood & Daily Journal: Log daily notes plus sleep, energy, and mood to see how your wellness patterns shift across each phase of your cycle. • Apple Health Sync & Widgets: Sync weigh-ins with Apple Health both ways and import your cycle history — restore up to 3 years of extended history, and log quickly from Home Screen widgets. • Private by Design: Your health and cycle data stays exclusively on your device and in Apple Health, and is never sold. The free version is supported by ads; Pro removes them. Stop guessing. Stop panicking over normal fluctuations. Start understanding your body’s natural rhythm.
