Just Spent
A native iOS and Android prototype for logging everyday expenses as quickly as speaking a sentence.
Just Spent started with one simple idea: tell Siri or Gemini something like "I just spent 20 dollars for groceries," and let the app log the expense for you.
The product bet is that expense tracking becomes more useful when capture happens at the moment of spending, without opening a heavy form or finance dashboard.
What this demonstrates: cross-platform product architecture, AI-assisted implementation discipline, test-heavy development, local-first storage, and honest tracking of what is still blocked.
Product Highlights
Voice Expense Capture
The intended flow is to tell Siri or Gemini what was spent and have the app create the expense automatically.
Multi-Currency Tracking
Expenses can be grouped by currency, with the default currency coming from the device locale and new currency views created as needed.
Fast Categorization
Common words like coffee, fuel, taxi, grocery, rent, medicine, books, and shopping map to useful spending categories.
Local App Storage
The basic expense history is designed to work without a server, using Core Data on iOS and Room on Android.
Assistant Entry Points
Siri, Shortcuts, Android voice, shortcuts, and App Functions are the planned surfaces for assistant-driven logging.
Test-Heavy Development
Unit, UI, integration, and local CI checks are part of the core experiment, not an afterthought.
Technology Stack
iOS App
- SwiftUI screens for onboarding, single-currency, and multi-currency expense views.
- Core Data repository layer for creating, listing, deleting, and paginating expenses.
- Status docs show 105/105 unit tests and 80/81 UI tests passing.
Android App
- Compose screens for expense lists, filters, onboarding, settings, and voice entry.
- Room database, DAO, repository, preference, permission, and lifecycle layers.
- Status docs show 145/145 unit tests passing, with two remaining phone UI test failures in the edit flow.
Shared System
- Shared currency and test data support cross-platform consistency.
- Local CI scripts are documented for fast and full checks.
- Deployment is still planned, so this page does not imply a finished store release.
Current Blockers
iOS Assistant Flow
The goal is natural voice logging through Siri, not just opening the app. That path is waiting for newer Siri and App Intents improvements to be reliable enough.
Android Assistant Testing
The Android idea moved toward Gemini and app actions, but Play Console testing and setup became a blocker before the flow could be validated end to end.
Multi-Currency UI Test
One UI test still fails around expected currency tabs, so the next check is UI state, accessibility identifiers, and tab generation timing.
Edit Dialog Tests
Two phone UI tests still fail around the edit dialog: one around the Cancel button timing and one around category dropdown visibility.
Phone-Only Testing
The app is phone-only. CI should consistently use a phone AVD such as a Pixel profile so tablet emulators do not create false failures.
Release Readiness
Deployment guides and Fastlane lanes exist, but store submission, beta testing, and post-launch monitoring remain planned work.
Repository Entry Points
The repository is structured as a studyable system with architecture notes, testing guidance, status docs, and platform-specific implementation specs.
