Nexmy

Nexmy is an offline-first personal finance app for Android that tracks spending, budgets, accounts, and installments without requiring an internet connection or a user account. Your data stays on your device, and you control when and how to back it up. There's no cloud sync, no mandatory sign-up, and no external service parsing your financial information.

The app covers the core of personal finance tracking: expense and income logging, account management, savings goals, and budget planning. What sets it apart is how it handles installments. Buy-now-pay-later plans, loans, and mortgages are integrated directly into the spending flow. You can see monthly impact and payment status alongside your regular transactions, which helps you understand what you actually owe rather than just what you spent this week.

There's an AI assistant called Smarty built into the app. It works offline and lets you request summaries, guided actions, and quick updates using natural language instead of tapping through menus. You can ask for a spending breakdown or log a transaction by describing it, and Smarty handles the navigation. Because it runs locally, the AI doesn't send your queries to an external server.

Analysis tools include charts and category breakdowns that show where your money goes. Budget and objective planning are integrated into one interface, so you can set limits and track progress without jumping between screens. The installment tracker shows remaining balances and provider information for each plan, which is useful if you're juggling multiple payment schedules.

Data control is explicit. Everything stays on the device, and you can export or import a local backup whenever you want. There's no account required to use the app, which means no password to remember and no risk of a service shutting down and taking your history with it.

Nexmy is free and available on the Google Play Store. The platform is Android only, so iPhone users are out of luck. It's aimed at anyone who wants to track personal finances without trusting a third party with their data, and the offline AI assistant is a genuine differentiator for people who want convenience without the cloud.
