Steady

A tiny, private habit tracker for iPhone.
Install, add habits, done.

Why

I couldn't find a tiny, simple habit tracker on the App Store. The ones I tried weighed hundreds of megabytes, locked widgets behind subscriptions, or showed ads. I also wanted to see how far Claude Code could go in building a native iOS app, so Steady was built with it end to end.

Features

• Start or stop habits. Build a habit, or quit one. Stop habits can count every day as clean automatically, so you only log slips.
• Strict or forgiving. Strict shows your current streak. Forgiving counts every success day, so one bad day never resets your progress.
• Backdating. Start a habit in the past, with an optional "I did it every day since then".
• Widgets. Small, medium and large Home Screen widgets, all free.
• Notes and history. Add a note to any day and browse past months in a calendar.
• Smart reminders. A daily reminder per habit that stays quiet once you've logged the day.
• Your data, your files. Export a JSON backup or a CSV spreadsheet, and import backups.
• Black and white by design. Color comes only from your habits. True black in dark mode.
• In English, French, Spanish and German.

Tech

Swift 6 · SwiftUI · SwiftData · WidgetKit · App Intents · UserNotifications · StoreKit 2 · iOS 17+

• Days are stored as integer keys (20261102), not Dates, so streaks survive time zones and daylight saving changes.
• All counting logic is pure and unit tested (Shared/DayResolver.swift, Shared/HabitStats.swift).
• Widgets read a small JSON snapshot written by the app, never the database.

Build

Requires Xcode and XcodeGen.

brew install xcodegen
xcodegen generate
open Steady.xcodeproj

Run tests:

xcodebuild test -scheme Steady -destination 'platform=iOS Simulator,name=iPhone 17'

The Supporter Pack can be tested for free in the simulator through the bundled Steady.storekit configuration (run from Xcode). iCloud sync is implemented but switched off (FeatureFlags.iCloudSync) until the iCloud container is set up.
