Frequently Asked Questions
Why do women gain weight right before their period?
During the luteal phase (the 7β14 days before your period starts), progesterone and estrogen levels surge and drop, triggering the release of aldosterone β a hormone that causes kidneys to retain sodium and water. It is completely normal for women to temporarily gain 2 to 5 pounds of water weight during this phase, which naturally sheds within a few days of menstruation starting.
How does HerWeigh help with pre-period weight gain?
HerWeigh overlays your menstrual cycle phases directly onto your weight charts. When the scale suddenly jumps 2 lbs in your luteal phase, HerWeigh contextualizes it as normal hormonal water retention rather than fat gain, saving you from unnecessary diet stress or restriction.
How is HerWeigh different from Happy Scale or MyFitnessPal?
Standard weight trackers like Happy Scale or MyFitnessPal treat every day in isolation or apply generic moving averages that ignore hormonal biology. HerWeigh is built specifically for women, combining trend-smoothing algorithms with cycle phase tracking so you can compare current weights against corresponding phases in previous cycles.
Can I sync HerWeigh with Apple Health?
Yes! HerWeigh offers full two-way synchronization with Apple HealthKit. You can automatically import your historical weigh-ins, smart scale measurements, and menstrual flow logs, keeping all your health data unified.
Do I need to count calories or log my meals?
No. HerWeigh is entirely free from calorie counting, food logging, and diet dogma. It is designed to be a peaceful, fast companion where logging takes less than 5 seconds a day.
Is my health and cycle data kept private?
Absolutely. HerWeigh stores your data locally on your device and in your private iCloud account. We do not use third-party analytics trackers, do not run ads, and never sell or share your personal health data.
