## What is DayByDay?

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.

PLANS
• Free, forever: every log, Apple Health sync, your full history and spreadsheet export
• Core: trends and goal dates, Dayo, Sleep Score, the Energy Schedule, the estimated level chart, milestones, the Sky look, Home Screen and Lock Screen widgets, and PDF reports for your care team
• Plus: everything in Core, plus food search, barcode, label and plate-photo logging
• New accounts get 14 days of full Plus, free, with no card. After that you stay on Free unless you choose a plan.

Core and Plus are auto-renewing subscriptions, billed monthly or yearly to your Apple Account. They renew unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.

Estimates are not measurements and not a guide for dosing, eating or treatment. DayByDay doesn't monitor your readings or alert anyone. In an emergency, call 911 or your local emergency number.

### 3.0 — 2026-07-10

Welcome to DayByDay 3.0 — the biggest version we've ever built.

We rebuilt DayByDay around one idea: your journey is so much more than a number on a scale. Here's what's new.

MEET DAYO, YOUR AI COACH
Every morning, Dayo reads your real data and writes you a short, honest note about what's working — the stalls, the wins, and what's quietly changing. No generic advice. Every insight is backed by evidence you can tap.

FOOD LOGGING THAT DOESN'T FEEL LIKE A CHORE
Snap a photo of your plate and let AI turn it into calories and macros in seconds, or search millions of foods from FatSecret's trusted database. Track protein, fiber, and water with a single tap — no tedious food diary, no shame.

A BRAND-NEW HOME
Five simple tabs: Today, Track, Nutrition, Insights, and You. Everything you log now lives one tap away, and you can show, hide, and reorder the cards on your Today screen to make it truly yours.

KNOW YOUR ENERGY
A whole new Energy Schedule predicts your morning peak and afternoon dip, tuned to your own sleep and rhythm — so you can plan your hardest work for when you'll actually have the fuel for it.

MOMENTUM THAT REWARDS SHOWING UP
Your new Momentum Score climbs as you stay consistent, with gentle reminders so a good streak never slips away by accident.

SHARE YOUR WINS
Turn your progress into a gorgeous share card — pick from confetti, a calm ocean, a beach day, or a mountain view — and post it to Instagram, Stories, or anywhere you like.

DEEPER GLP-1 CARE
A pharmacy and refill hub, an injection-site rotation advisor, richer side-effect tracking, and one clean sheet to log every dose. Plus a doctor-ready summary PDF for your next visit.

SLEEP AND RECOVERY, EXPLAINED
Tap your Sleep Score to see exactly how it's built, get a Resilience Score, and see your overnight oxygen, heart rate, and breathing — each with plain-English tips on what to improve first.

WIDGETS
Put your weight, medication level, and next-shot countdown right on your Home Screen and Lock Screen.

A WARMER, CALMER APP
Journey Mode, our sunset theme, got a head-to-toe polish, and the whole app now feels smoother, lighter on your battery, and more like a place you actually want to come back to.

...plus hundreds of small fixes and refinements, and insights that always stay honest to your real history.

Thank you for being here. One day at a time.

### 2.2 — 2026-05-19

v2.2 — The biggest update yet.
This release is for everyone walking the full road: losing weight, holding the line in maintenance, or coming back from a regain. 

Here's what's new:

MEET DAYO — YOUR AI COACH
Every morning, Dayo reads your last 30 days of weight, sleep, exercise, GLP-1 doses, blood glucose, and mood — and writes 1–3 plain-language insights about what's actually happening. Every claim is grounded in a real number. Tap "Show all evidence" and you'll see exactly which data shaped each insight. Nothing made up. Nothing generic.
• Daily affirmations that actually vary day-to-day
• Knows your medication, current dose, and schedule
• Surfaces titration stalls and lean-mass-loss warnings
• Pick what time of day your Coach Note arrives
• Per-source opt-out — exclude any data category from what's sent

HOME SCREEN + LOCK SCREEN WIDGETS
Five native widgets that put your journey one glance away:
• Today widget — current weight, trend, medicine level, next-shot countdown
• Water widget with one-tap quick-add (works offline)
• Lock screen streak inline
• Lock screen med-level ring
• Lock screen next-shot rectangular complication

PHARMACY & REFILL HUB
Because the hardest part of GLP-1 isn't the shot — it's the pharmacy.
• Refill cadence tracking with pickup history
• Prior-authorization renewal reminders (1–8 weeks ahead)
• Pen storage countdown so a $1,000 pen never gets thrown out
• Missed-dose protocol per FDA label — when to take, when to skip
• Optional pharmacy contact info, tap to call

MAINTENANCE & REGAIN MODES
Most weight-loss apps drop you off at "goal reached." DayByDay travels the whole road.
• New Maintenance Range card — drift from goal, in-range streaks, days at goal
• Maintenance milestones at 30, 90, 180, 365, and 730 days
• Gentle, shame-free regain detection with comeback guidance
• The app's tone and projections adjust to where you actually are

DEEPER BODY COMPOSITION
• DEXA scan integration — body fat %, lean mass, bone density, T-score, visceral fat
• Lean-mass loss warning flags >10% drops with protein and resistance-training guidance
• Body-fat % goal with projected estimates
• Progress photos timeline with weight + dose stamped on each (private, encrypted)

EXPANDED GLP-1 SUPPORT
• Compounded semaglutide & tirzepatide with concentration field
• Rybelsus (oral semaglutide) support with empty-stomach reminders
• Side-effect severity (0–10) with peak-day heatmap
• Travel-aware dose timing anchored to home timezone
• Pause / vacation mode
• Medication switcher with full event log
• Pre-dose checklist
• Dose-cycle patterns and loss-by-dose comparison

DAILY LOGGING UPGRADES
• Daily protein tracker with research-grounded targets
• Blood glucose with meal-time tags
• GI tracker with Bristol stool scale
• Mood / State of Mind entries

SLEEP SCORE + RESILIENCE SCORE
Powered by Open Wearables — the same scoring engine across every device you connect.

DOCTOR-READY PDF EXPORTS
A one-page visit summary with dose history, side effects, weight delta per dose level, and A1c trend.
Plus dozens of polish improvements, a refreshed onboarding flow, and a beautiful new Journey Mode dark theme with a time-of-day sunset gradient.

Thank you for being part of the journey.
