Periscope is a private, completely free weight tracker built around a simple daily weigh-in. Whether you're losing weight, building muscle or just staying accountable, Periscope shows you where you're really heading, without the noise. SEE THE REAL TREND Your weight naturally jumps around day to day. Periscope's smoothed trend line cuts through the fluctuations so you can see true progress. Browse weekly, monthly, yearly or all-time views and tap any point to see that day's weight. REPORTS THAT MOTIVATE The new Reports tab gives you a card for every week, month and year: your lowest weigh-in, how it compares with last time, your trend rate per week, and your BMI. Drag across any chart to explore day by day, and share a report with friends. APPLE HEALTH SYNC Use a smart scale? Connect Apple Health and your weight history comes in automatically. Weights you log in Periscope are saved to Health too, so your other health and fitness apps stay up to date. WIDGETS Keep your progress in sight with Home Screen and Lock Screen widgets: this month's report, your trend chart, key stats and your goal progress. PROGRESS PHOTOS Attach photos to any weigh-in and use the smooth before-and-after slider to see how far you've come. GENTLE REMINDERS Get a friendly nudge to weigh in, every 3 days by default, or as often as you like. PRIVATE BY DESIGN Your weight and photos stay on your device unless you turn on backup. Backups are stored privately in your account, never shared or sold, and you can turn backup off anytime. Face ID can lock the app so only you can see your data.
