A robust, offline-first mobile application built to track personal expenses and manage peer-to-peer settlements. Designed with a clean, themeable UI and engineered for performance, Hisab ensures your financial data is always accessible, even without an internet connection.
- ** Offline-First Architecture:** Add, edit, and delete transactions locally. The app automatically queues your changes and syncs them to the cloud in the background once you're back online.
- ** Peer-to-Peer Settlements:** Track exactly who owes you and who you owe. Easily mark debts as "Paid" and instantly see your net pending settlements.
- ** Interactive Analytics:** Visualize your spending habits with dynamic pie charts broken down by category and by person.
- ** Dynamic Theming:** Choose from 6 beautifully crafted professional themes (Light, Dark, Coffee, Ocean, Forest, Purple) that adapt the entire UI instantly.
- ** Enterprise-Grade Security:** Secure authentication powered by Clerk, supporting Google SSO and secure email verification.
