When managing daily finances, I wanted a tool that met a few specific personal requirements:

Multi-device access without heavy infrastructure: Pure mobile apps are great for quick logging, but they keep your data trapped on a single phone. I wanted to manage budgets from both my desktop and mobile, without having to spin up a 1GB–2GB Docker stack (like Firefly III).

Instant logging on the go: Even though it is a web-first application, logging an expense should not depend on a server roundtrip when mobile reception is poor.

Integrated rental tracking: I needed to track monthly apartment rent, tenant advances, and utility splits alongside my personal day-to-day expenses.

To solve this, I built Hishab —a Vue 3 and Laravel 13 web app (packaged as a PWA and Android WebView) running on a 256MB free host.

How it is structured:

Local-First with IndexedDB: All writes go to browser storage first (0ms feedback) and sync to the server in the background using the Web Locks API for concurrency safety.
