AI calorie counter and food scanner for iPhone and Apple Watch. Snap a meal, get instant macros, log water, plan workouts, and follow a diet that fits your day - all fully on-device, no account needed, synced via iCloud.
FitBytes turns your iPhone and Apple Watch into an intelligent coach for food, water, and workouts. Built natively in SwiftUI for iOS 26, with on-device AI, iCloud sync, and a Liquid Glass design.
A WALKTHROUGH
1) TODAY — your daily dashboard
A motivational quote that shifts with the time of day and what you've already done greets you on every open. A calorie ring shows consumed vs. target with live macro breakdown (protein, carbs, fat, calories burned, net). Below it: meal suggestions that fit your remaining budget, a diet-plan progress bar, water quick-add chips (+250 / +500 / +750 ml), and the day's planned workouts with a tick-off circle that auto-creates the entry.
A floating Liquid-Glass + button is your one-tap launchpad: scan food, search food, log a workout, or log measurements.
2) SCAN A MEAL
Point your camera at a plate. On-device Core ML and Vision identify the food and estimate the portion. Label, grams, and macros pre-fill — confirm and save. No upload, no internet.
3) SMART FOOD REPLACEMENTS
Out of paneer? FitBytes shows the equivalents from a coach-approved replacement sheet:
• 50 g paneer = 2 whole eggs = 100 g chicken
• 50 g rice = 75 g bread = 200 g potato
• Almonds ↔ walnuts ↔ cashews ↔ peanuts
Tap a swap and the entry updates with the right macros.
4) FOOD TAB — one recipe at a time + eat-out
We show ONE meal-fit recipe with swappable ingredients, a single-tap log button per item, and a one-tap "Log all". Going out? An "Eat out" section finds restaurants near you and proposes a plate that fits your remaining macros — no leaving the app.
5) WORKOUT TAB
Log strength, cardio, HIIT, yoga, walks, runs. Apple Health auto-imports steps, active calories, and sleep. Generate goal-based weekly splits (fat loss, muscle gain, mobility, hybrid), repeat them for as many weeks as you like, and tick sessions off from Today.
6) PROGRESS — body, goals, every metric
Log weight, chest, waist, hips, abdomen, body-fat in one tap. Trend charts for 1d / 1w / 1m / 1y of every metric. Above: a Goal Tracker with weekly snapshots and monthly progress photos.
7) APPLE WATCH APP
Swipe-to-page Watch app for fast logging on the wrist:
• Home — calorie ring + protein / water / workout summary
• Water — three big +250 / +500 / +750 ml buttons
• Quick log food — meal slot picker plus 10 curated presets
• Workout — pick a type, dial in minutes with the Crown, tap Log
Entries flow back to the phone instantly when reachable, queued when not.
8) DIET PLANS
Build a plan meal-by-meal or paste in JSON / free-form text from another app and FitBytes parses it into a structured plan with totals plus daily adherence scoring.
9) PROFILE & THEMES
Edit your goal, targets, and units. Pick a theme — or let the app auto-tint to your goal so the whole UI shifts color as your priorities change.
10) SHARE — coach or partner view
Tap "Create share link" for a private CKShare URL. Send via Messages, Mail, or AirDrop. The recipient accepts in iCloud and follows your tracker live. Revoke anytime.
ICLOUD SYNC
Stored in your private iCloud database (SwiftData + CloudKit). Syncs across iPhone, iPad, Mac, and Apple Watch. End-to-end encrypted by Apple.
