I'm a solo developer and I built BiteDeck because every calorie tracker I tried wanted an account, served ads, and kept my food diary on their servers.
BiteDeck has no backend. Your data lives on the device (local SwiftData), there's no account, and the weight-forecast math runs on-device. The only outbound calls are a thin stateless proxy for the optional photo-scan, which sends one image to Gemini Vision to identify the food and doesn't retain it. You can avoid that entirely โ barcode, nutrition-label OCR, search, and manual entry are all on-device.
Some technical bits this crowd might find interesting: - 151,700-food database shipped as SQLite + FTS5, primed at launch so search is instant and works offline - Every chart is custom Canvas (no chart library); the UI is a skeuomorphic instrument panel done in SwiftUI - Apple Health is a fire-and-forget mirror; SwiftData is the source of truth - WidgetKit widgets + an Apple Watch companion sharing an App Group store
It's free, with a paid tier ($14.99/mo or $69.99/yr) for the heavier features. iPhone, iOS 17+. For anyone without an iPhone, there's a plain overview at https://bitedeck.app
Feedback and hard questions welcome โ especially on the data model and the on-device forecasting.

Swift and SwiftUI (iOS 17+), SwiftData for local on-device storage, Swift Concurrency, HealthKit, and WidgetKit. The camera and scanning use AVFoundation and Apple's Vision framework; food search runs on a bundled SQLite database with FTS5 full-text search; and all the charts are custom Canvas drawings (no third-party chart library). The AI photo scan goes through a lightweight serverless proxy (TypeScript on Vercel) to Google Gemini. There's also a watchOS companion app.
BiteDeck is a calorie tracker that runs entirely on your iPhone โ no account, no ads, and no server holding your data. You can log a meal just by taking a photo, search a 151,700-food database with 282 restaurant chains fully offline, sync with Apple Health, and it forecasts your weight right on the device. It also looks like nothing else in the category: a skeuomorphic "instrument panel" interface with VU meters and segment displays that makes tracking feel like using a well-made piece of hardware instead of a chore.
Most trackers make you create an account, show you ads, and keep your food diary on their servers. BiteDeck does none of that โ your data stays on your phone, there are no ads in any tier, and there's no account to create. The everyday essentials are free; the only paid features are the AI ones (the photo scan and the AI coach), because those genuinely cost money to run. So you're never paying just to remove ads or to unlock basic logging the way you are with MyFitnessPal or Cronometer โ you only pay for the features that cost real money to operate.
People who track calories or macros and are tired of the ads, paywalls, and account requirements of mainstream apps. That includes anyone losing weight or managing their nutrition, intermittent fasters, the privacy-conscious who don't want their health data sitting on a company's servers, and the quantified-self crowd who want to own and export their own data. iPhone users on iOS 17 or later.
BiteDeck was built by a solo developer who used MyFitnessPal for years and watched it get worse โ ads between every meal, basic features sliding behind a paywall, and an account required just to count calories, with all that food and health data sitting on someone else's servers. The breaking point led to building the opposite: a calorie tracker that keeps everything on your phone, never asks for an account, and never shows an ad. The distinctive instrument-panel design came from a simple idea โ that tracking your food should feel good, like using a great piece of hardware, instead of feeling like a chore.
