Track your weight, medication, sleep, and body changes — and actually understand what’s working. No food logging. No calorie counting. Just results.
Perfect alongside your favorite food tracking app — or on its own if you'd rather let your GLP-1 do the work and just track what matters.
DayByDay learns your patterns and gives you insights you won't find on a bathroom scale.
Hit 10% lost? Confetti. Reach your goal? You earned every bit of it. Milestones are celebrated, not just noted.
Based on your real trend — not wishful thinking. See when you'll reach each milestone with confidence ranges.
Personalized insights that actually make sense. "You're losing 2.3 lbs/week." "Your sleep improved this week." Real talk, not filler.
See your check-in streak, exercise consistency, and medication adherence. Discover what's actually moving the needle.
Weight, steps, sleep, workouts — it all flows in automatically. No double-entry. Just open the app and it's there.
Export a PDF report or CSV of any data — weight, meds, labs, everything. Walk into your appointment with real numbers.
Whether you're just starting or breaking through a plateau, DayByDay gives you the clarity to keep going.
Encrypted at rest. No ads. No selling your information. Delete everything anytime.
No calorie counting. No macro tracking. Just track what's actually changing — your weight, your body, your health.
