DayByDay is a personal tracking tool and general information guide to use with your care team. It doesn't diagnose, treat or monitor any condition. For adults 18 and up.
Log your weight, food and water, sleep, steps and workouts, body measurements and, if you take one, your GLP-1 shot or pill, with reminders you set yourself. See your trend, not just today's number, and bring a clear report to your next visit.
YOUR TREND, NOT THE NOISE
• One smoothed trend line by real date, so one day's number doesn't define your week
• Goal dates as an honest range, plus milestones worth celebrating
FOOD THAT FITS REAL LIFE
• Calories, protein, fiber, carbs, fat and water on one calm screen
• One-tap Favorites, Copy yesterday and a running basket for a whole meal
• Search millions of foods, scan a barcode or nutrition label, or snap a photo of your plate (Plus)
• Type any food in by hand, free for everyone. Logging works offline.
YOUR GLP-1, ON THE RECORD
• Log a shot or pill in a few taps. The site you used longest ago is already picked, and you can choose any other
• Reminders on shot day and the evening before, a check-in after you log, plus refill and prior-authorization dates
• An estimated medicine-level chart, labeled as an illustrative model, not a measurement
• Side effects and notes, ready for your next appointment
SLEEP AND ENERGY
• Last night's stages, a Sleep Score and sleep debt against your own sleep need
• An estimated energy curve for your day, with a caffeine cutoff and a wind-down window
INSIGHTS IN PLAIN WORDS
• Your week in a sentence: pace, fuel, sleep and activity
• Dayo, an optional AI-generated summary of what you log (you decide whether to allow it)
• Patterns in your logs, always labeled as patterns, not causes
YOUR DAY, EVERYWHERE
• Home Screen and Lock Screen widgets, a Live Activity with calories, protein and your next shot, plus Siri and Shortcuts
• Discreet mode keeps your medicine's name and your weight off the Lock Screen
• Layouts for iPhone and iPad, including iPhone Duo
PRIVATE BY DESIGN
• Works with Apple Health (optional). Your health data is never used for advertising or marketing, and never sold.
• No ads. Delete your account and everything in it, anytime, from Settings.
