Train, eat and track. Offline first.

One app, five tabs

• Home

  Today at a glance

  Calories and macros against your targets, today's protocols and Apple Health activity in one place.

• Nutrition

  Log food fast

  Search, scan a barcode, quick-add, reuse saved meals, or photograph a plate for an AI estimate you confirm before it is saved. Missing nutrients stay missing, never zero.

• Workout

  A compact set table

  Templates, weekly or rotating programs, automatic rest timers with a Live Activity and Dynamic Island countdown, and a recap when you finish.

• Body

  Trends, not noise

  Bodyweight with a seven-day trend, a 30-day chart and raw history. Sleep and movement are read from Apple Health and stay on the device.

• Protocols

  Daily check-offs

  Supplements, movement or anything else, grouped by time of day, with streaks that count only scheduled days. A protocol is a habit log, never nutrition intake.

How it's built

A solo project built end to end: native client, backend, infrastructure and release.

SwiftUI app

Swift 6, iOS 17+. Local SQLite via GRDB, so logging works offline and without an account. Views go through a store and repository layer, never straight to files or the network.

Sync

Changes are written to a local outbox in the same transaction as the data, then sent with idempotent requests, revision checks and explicit conflict resolution.

Go API

A Go service handles sync, food search and AI estimation, with integration tests against a real database.

PostgreSQL

Account data lives in Postgres on private managed infrastructure. Migrations are versioned and checked against the deployed binary.

AI food estimation

An optional photo-to-nutrition flow. The estimate is a draft the user reviews; the photo is not kept.

Sign in with Apple

Server-verified nonce and JWT, session in the Keychain. Signing out keeps local logs.

Hosting

The API runs on AWS Lightsail behind Caddy. Apple Health data never leaves the phone.

Testing

Simulator UI journeys per tab as the main quality gate, plus unit tests focused on sync, data safety, imports and migrations.
