Yes. Settings include CSV and PDF export via the Android share sheet for backups and summaries.
InsightlySpend is an ad-free, local-first Android personal finance app for tracking spending, budgets, insights, and receipt photos with Room storage and optional biometric lock.
Ad-free: Completely ad-free — no ads, no trackers, no sponsored clutter.
A local-first personal finance app for Android. Data is stored in Room; lists and summaries use observed queries so changes propagate across tabs when you add, remove, or duplicate transactions.
The bottom navigation has six sections: Home, Ledger, Insights, Budget, Vault (receipts), and Settings.
*GIF cycles through main tabs; regenerate after UI changes with python3 scripts/generate_readme_gif.py (requires Pillow).*

Architecture
The codebase follows a layered structure under app/src/main/java/com/michael/insightlyspend/:
| Layer | Role |
|---|---|
| Presentation (presentation/) | Jetpack Compose screens, ViewModels (StateFlow / coroutines), navigation (Navigation Compose). |
| Domain (domain/) | Use cases, repository interfaces, and domain models shared by UI and data. |
| Data (data/) | Room (DAOs, entities, DB), repository implementations, mappers, DataStore preferences, WorkManager workers, ML/adapters for Insights. |
Dependency injection uses Hilt (@AndroidEntryPoint, @HiltViewModel, modules under di/). Background work (e.g. recurring posting) uses WorkManager with Hilt worker integration.
Navigation: single-activity, `MainShell` hosts a bottom `NavHost` with typed routes (AppRoutes) and optional deep links (insightlyspend://nav/...) for tooling (e.g. Play Store screenshots).
Startup: MainActivity applies locale/theme; optional BiometricGate wraps the main shell when lock is enabled.

Home (Dashboard)
Purpose: High-level snapshot of your finances and a shortcut to add a transaction.
| UI element | What it does |
|---|---|
| Overview card | Total balance — sum of all wallet (account) balances. Income / Spend — this month’s total income vs total expenses. |
| Budget progress (if you have category budgets) | Linear bar — spend vs total monthly budget cap. “Spent X of Y” — numeric comparison. |
| Daily spending (7 days) | Line chart of expense totals per day for the last seven calendar days. |
| Recent transactions | Up to five latest rows (category, note, amount). Tapping the FAB is the main way to add more; the list updates when the database changes. |
| Floating action button (+) | Opens Quick add (see below). |
---
Quick add (bottom sheet)
Opened from the Home FAB. Creates a new transaction in Room and updates account balance.
| Field / control | What it does |
|---|---|
| Amount | Transaction amount (decimal). |
| Category | Picker of all categories; label follows your app language (English/Arabic names when set). |
| Wallet | Account to book the transaction against (affects total balance). |
| Income | If on, the line is treated as income; if off, as spending. |
| Cash payment | If on, payment method is cash; if off, card. |
| Recurring template | Marks the row for recurring/repeat logic where supported. |
| Debt / lending | Standard / I owe / Owed to me — how the amount relates to debt tracking. |
| Note | Optional text (searchable from the ledger). |
| Choose from gallery / Take photo | Gallery opens the system photo picker (images only). Take photo launches the device camera and saves into app cache via FileProvider; the URI is stored on the transaction so it appears under Vault. Remove image clears the selection before save. |
| Save | Inserts the transaction (with optional receipt URI) and closes the sheet. |
---
Ledger
Purpose: Full searchable list of transactions with filters and swipe actions.
| UI element | What it does |
|---|---|
| Search notes | Filters rows whose note contains the text (case-insensitive). |
| Cash only | When selected, only cash payment-method transactions. |
| This month | Restricts to start of current month → end of current month (and can stack with cash filter). |
| Clear filters | Removes date range and payment filters (search is separate). |
| Day group headers | “Today”, “Yesterday”, or a calendar date; rows are grouped by day. |
| Each card | Category icon, category name (localized), note, time, and signed amount (green + income, red − spend). |
| Swipe end → start | Delete that transaction (updates balance). |
| Swipe start → end | Duplicate — creates a new row with the same details and current time; original row stays. |
The ledger is driven by a Room `Flow`, so it stays in sync with the database.
---
Insights (Analytics)
Purpose: On-device analytics: forecast, month comparison, category mix, and simple anomaly hints.
| Section | What it does |
|---|---|
| Title | Screen heading. |
| Predictive forecast | Estimated month-end spend, optional confidence range; method name may reflect linear regression and/or a bundled ML model. |
| Month comparison | This month vs last month spend, and percent change when available. |
| Category breakdown | Pie and bar charts of share of spending by category (for the reporting window the engine uses). |
| Anomaly hints | Short bullet lines with a z-score-style stat for unusual days/categories, when the report includes any. |
This screen is built from a computed report; pull-to-refresh or reopening the tab refreshes it (it is not the same live Flow pipeline as Home, unless you extend it).
---
Budget
Purpose: See per-category monthly budgets that you have set, with spend vs limit; add or manage those categories from here.
| UI element | What it does |
|---|---|
| Title + hint | Explains that alerts can fire around high usage. |
| Loading / error | States while data loads or if something fails. |
| Each category card | Name (localized), Remaining, Spent X of Y, progress bar. Can highlight when past a threshold. |
| Edit (pencil) | Opens a sheet: English/Arabic names (per language rules), monthly budget for that category; Save updates Room. |
| Delete (bin) | Only if more than one category exists in the app. Confirms that transactions move to another category and recurring rules for that category are removed. |
| FAB (+) | New budget category — bilingual names, monthly budget amount, creates the category with a limit so it appears here. |
Only categories that have a monthly budget limit appear as rows on this tab.
---
Vault (Receipts)
Purpose: Grid of transactions that have an attachment image (receipt photo). Attach images when creating a transaction via Home → Quick add → Choose from gallery or Take photo; those rows show up here automatically.
| UI element | What it does |
|---|---|
| Title + hint | Describes storing image URIs on transactions in the database. |
| Each tile | Thumbnail of the image (or Attachment placeholder if the URI cannot be loaded), category, optional note. |
---
Settings
Purpose: Categories and recurring rules, app preferences, security, and exports.
Categories
| UI element | What it does |
|---|---|
| Section title | “Categories” — manage all categories. |
| Add category | Opens sheet with English and Arabic names (required/optional rules follow interface language). |
| Each row | Category label; edit opens the same bilingual editor; delete (if not the last category) merges transactions and clears recurring rules for that category (with confirmation). |
Recurring transactions
| UI element | What it does |
|---|---|
| Add rule | Opens editor for a monthly recurring rule. |
| Each rule card | Shows category, amount, day of month, wallet, optional note; edit / delete. |
| Rule editor fields | Amount, category, wallet, day (1–28), income, cash vs card, debt mode, note, Save. Saving enqueues a one-time background job so a charge can post soon if today’s calendar day matches the rule’s day (once per month). Daily periodic work also runs as a backup. Posted rows appear on Home and Ledger like any other transaction (Room flows). |
Rest of Settings
| UI element | What it does |
|---|---|
| Currency | Chips (USD, EUR, GBP, AED, SAR, EGP, JPY, INR, …) — display/formatting for amounts. |
| Language | System, English, or Arabic — UI strings and category/name picking behavior. |
| Theme | System, Light, or Dark. |
| Biometric lock | When enabled, unlocking uses device biometrics before showing the app (see startup gate). |
| Export CSV / Export PDF | Generates files and opens the Android share sheet so you can save or send backups/summaries. |
---
Startup & theme
- MainActivity applies language (via
AppCompatDelegate) and Compose theme from saved preferences. - If biometric lock is on, BiometricGate asks you to authenticate before MainShell (tabs) is shown.
---
Data flow (single source of truth)
- Transactions, accounts, categories, recurring rules live in Room.
- Home summary reacts to database changes via observed flows (transactions, accounts, categories); collectors use eager sharing so updates still arrive when other tabs were foreground (e.g. recurring worker inserts a row).
- Ledger observes filtered transactions as a Flow (same eager behavior).
- Budget and Categories sections observe categories / budget calculations as appropriate after writes.
