Nutrition Tracker · Local-First · No Account Needed
A nutrition tracker for people who actually track. Local-first. No account. Built for accuracy.
§ 02 · What's inside
Every entry path lands in the same logged meal. Every macro syncs the same way. Every chart runs on the same phone.
Feature 01 · Scan
Snap a photo. BiteDeck reads the plate, estimates portions, and hands you editable totals in seconds. Or scan a barcode. Or point at a nutrition label.
Feature 02 · Menus
235+ restaurant chains with per-item macros, sorted by section, scoped search inside the menu, multi-add. No hunting through generic calorie counters.
Feature 03 · Apple Health
Reads steps, active energy, workouts, weight, body fat. Writes calories, every macro, fiber, sugar, sodium, water, weight, body fat. Every metric has its own toggle. No all-or-nothing.
Feature 04 · Coach
Your Coach gets on-device context about today — not your whole chat history. Delete anytime. No training on your meals. No ads. Ever.
Your protein has been trending low this week. Want a meal that hits 35g with ~450 kcal?
Yes. Something fast.
Greek yogurt bowl · 1 cup 2% Fage + 1 scoop whey + berries. 36g P, 440 kcal, 4 min prep. Log it?
Feature 05 · Forecast
A five-state forecast predicts your goal date, flags reversed trends, and charts your actual deficit against the plan. All math runs locally. Nothing leaves your device.
Feature 06 · Fasting
Pick a protocol. Milestone notifications fire at 25 / 50 / 75%. Completed 20-hour-plus fasts protect their streak day automatically. Built in. Not a separate app.
§ 03 · Why BiteDeck
Your data stays with you. Forecast math runs on-device. HealthKit is the only integration — opt-in, per-metric, reversible.
Open the app and start tracking. No signup, no email, no magic link. Your iPhone is the identity.
Premium is optional. The free tier is fully functional — every scan path, the whole food database, Apple Health sync, forecasts, Coach.
§ 04 · The look
Every token below came from a vintage instrument panel — segment displays, VU meters, recessed dark glass, mechanical keycaps — translated faithfully to SwiftUI and then to this page.

§ 05 · Questions
Yes, bidirectionally. BiteDeck reads five metrics — steps, active energy, workouts, weight, body fat % — and writes nine: calories, every macro, fiber, sugar, sodium, water, weight, and body fat. Every single metric has its own toggle, on top of the iOS permission. Turn any one off without disconnecting everything.
Your logs live in SwiftData on your device. If you have iCloud device backup on at the iOS level, BiteDeck's data is included automatically — no separate cloud sync to a BiteDeck server. You can export everything as CSV or a 30-day PDF summary any time.
You snap a photo. It goes through BiteDeck's own proxy to Google Gemini Vision for recognition, then the item list comes straight back to your phone. BiteDeck doesn't retain your images or train on them. If you'd rather not scan, every meal can be logged by search, barcode, nutrition-label OCR, or freeform entry.
No subscription required. Every logging path, the whole 13,593-food database, 235+ restaurant chains, Apple Health sync, on-device forecasting, fasting, and the Coach are in the free tier today. Premium is planned — nothing in the app is gated right now.
iPhone only, iOS 17 or later, portrait orientation. No iPad layout, no watchOS app, no Android. The entire design leans on iOS-specific primitives (HealthKit, SwiftUI, SwiftData) — a port would be a different product.
Four ways: manual entry, the US Navy method (neck/waist/hip measurements with cm↔in toggle), the Deurenberg formula from BMI + age + sex, or imported from Apple Health. Every saved entry feeds both the Home Composition page and the Katch-McArdle BMR calculation that drives your calorie target.
A five-state forecast engine (locked / unlocked / goal-reached / maintaining / reversed) runs on your phone. It uses a 14-day lookback and a 7-day rolling average, adjusting for your actual deficit against maintenance TDEE. It never talks to a server — the whole thing is on-device math.
Yes. Fasts of 20 hours or longer protect their end-day as a logged day automatically — you can do a fast-only day and keep your streak. Milestone notifications fire at 25, 50, and 75% of your target. Protocols: 16:8, 18:6, 20:4, OMAD, or custom 1–72 hours.
Type a brand name — "In-N-Out," "Chick-fil-A," "Chipotle" — and a dedicated menu card surfaces with every item sorted by section (burgers, shakes, fries, sides). Scoped search inside the menu, sort by section/name/calories, filter by section, multi-add. 235+ chains in the database.
Because the whole design leans on iOS-specific primitives — HealthKit, SwiftUI, SwiftData, the on-device Gemini pipeline, Doto at fixed sizes, skeuomorphic modifiers that only exist in Apple frameworks. A port would be a different product. Not planned.
