Powered by v-star.**\n\nStop wrestling with Excel. Stop praying your VBA doesn't crash on the big file. v-desktop puts a full actuarial toolkit in a native desktop app — present values, annuities, mortality tables, reserves, Monte Carlo simulations, risk metrics, and census processing — all running on the v-star engine.\n\n![Wails build](https://github.com/lubasinkal/v-desktop/actions/workflows/build.yml/badge.svg)\n![License](https://img.shields.io/badge/License-MIT-green)\n![Latest release](https://img.shields.io/github/v/release/lubasinkal/v-desktop)\n\n[![Windows](https://img.shields.io/badge/Windows-download-blue?logo=windows)](https://github.com/lubasinkal/v-desktop/releases/latest)\n[![macOS](https://img.shields.io/badge/macOS-download-black?logo=apple)](https://github.com/lubasinkal/v-desktop/releases/latest)\n[![Linux](https://img.shields.io/badge/Linux-download-orange?logo=linux)](https://github.com/lubasinkal/v-desktop/releases/latest)\n\nGrab the latest build from [Releases](https://github.com/lubasinkal/v-desktop/releases/latest).\n\n| Platform | File to download |\n|----------|-----------------|\n| Windows | `v-desktop-windows-installer.exe` (installer) or `v-desktop-windows.exe` (portable) |\n| macOS | `v-desktop-macos` |\n| Linux | `v-desktop-linux` |\n\n---\n\n## The Pitch\n\nEvery actuarial tool I've used is either slow (Excel), opaque (proprietary), or both. So I built v-desktop:\n\n- **9 tools** in one tabbed app: PV, annuities, mortality, reserves, Monte Carlo, risk, census, rates\n- **Dark terminal theme** — looks good, easier on the eyes during late-night runs\n- **Real actuarial math** — backed by [v-star](https://github.com/lubasinkal/v-star), which does 380M PV calculations per second\n- **Cross-platform** — Windows, macOS, Linux, one binary\n- **No cloud** — everything runs locally on your machine\n\n---\n\n## Tools\n\n| Tab | What it does |\n|-----|-------------|\n| **Dashboard** | Quick calculators: PV, life annuity, Monte Carlo |\n| **PV \u0026 Duration** | Present value (standard \u0026 v*), bulk PV, Macaulay/Modified duration, convexity |\n| **Annuities** | 10 annuity types: whole-life, term, deferred, NSP, endowment, approximations |\n| **Mortality** | Browse CSO 2017 tables, query qx/px/ex, chart curves, load custom CSVs |\n| **Reserves** | Net premium, gross premium, prospective, retrospective |\n| **Monte Carlo** | GBM \u0026 Vasicek simulations with path visualization and distribution charts |\n| **Risk** | VaR (95%/99%), CTE (95%/99%), confidence intervals, standard error |\n| **Census** | CSV census processing — sequential or parallel with configurable workers |\n| **Rates** | Rate converter (effective/nominal/force) and annuity-certain |\n\n---\n\n## Built With\n\n| Layer | Technology |\n|-------|-----------|\n| Desktop shell | [Wails v2](https://wails.io/) — Go + native WebView |\n| Actuarial engine | [v-star](https://github.com/lubasinkal/v-star) v0.7.0 |\n| Frontend | Vanilla JS, CSS3, HTML |\n| Charts | [Chart.js](https://www.chartjs.org/) v4.5.1 |\n| Bundler | [Vite](https://vitejs.dev/) v3 |\n| Mortality tables | CSO 2017 Male \u0026 Female (embedded, 0–120) |\n\n---\n\n## Quick Start\n\n```bash\n# Prerequisites: Go 1.26+, Node 20+\n# Install Wails CLI\ngo install github.com/wailsapp/wails/v2/cmd/wails@v2.12.0\n\n# Clone and run\ngit clone https://github.com/lubasinkal/v-desktop.git\ncd v-desktop\nwails dev\n```\n\nThis opens the app in a native window with hot-reload on frontend changes.\n\n### Build a Release Binary\n\n```bash\nwails build\n# Output: build/bin/v-desktop (or v-desktop.exe on Windows)\n```\n\nOr use the [GitHub Actions workflow](.github/workflows/build.yml) — tag a commit and it builds Linux, Windows (with NSIS installer), and macOS automatically.\n\n---\n\n## Screenshots\n\n*Coming soon — the app has 9 tabs. Open an issue if you want to see specific ones.*\n\n---\n\n## Who It's For\n\n| Person | Why v-desktop |\n|--------|--------------|\n| **Actuarial student** | Check your manual calculations against a real engine. Learn by doing. |\n| **Actuary** | Quick ad-hoc calculations without spinning up Excel or R. |\n| **Analyst** | Process census CSVs, run simulations, get risk metrics — all from one app. |\n| **Developer** | Example of a production Wails + v-star app. Steal the patterns. |\n\n---\n\n## Project Structure\n\n```\nv-desktop/\n  main.go              -- Entry point, Wails bootstrap, embeds mortality tables\n  app.go               -- App struct, wires 7 service backends, 29+ bound methods\n  wails.json           -- Wails project config (1280×900 window)\n  pkg/\n    models/            -- Shared request/response structs\n    services/          -- 7 services: rates, mortality, annuities, reserves, risk, stochastic, census\n  frontend/\n    src/\n      main.js          -- SPA entry, tab registration\n      app.css          -- Dark theme (500+ lines)\n      lib/             -- Tab navigation, Chart.js helpers\n      components/      -- 9 tab component modules\n  tables/              -- Embedded CSO 2017 mortality CSV files\n  .github/workflows/   -- CI: multi-platform build + GitHub Release on tag\n```\n\n---\n\n## Roadmap\n\n- [ ] In-app CSV census results export\n- [ ] Scenario comparison side-by-side\n- [ ] More mortality table sources (SOC, pension tables)\n- [ ] v-star API for custom scripting\n\n---\n\n## License\n\nMIT — do whatever you want with it.
