I’m a factory worker. I couldn't afford cloud servers, so I used AI to build a 100% offline personal finance app.
Hi everyone! 👋
A while ago, financial stress and the sheer amount of mental clutter (tracking budgets, split-payments, loans) got overwhelming. I wanted a finance app, but every single tool on the market forced me to create an account, connect a bank, or upload sensitive data to cloud servers I don't control.
To make things harder: I don't come from a traditional software engineering background, and I couldn't afford expensive cloud backend infrastructure. So, I turned that limitation into my strongest advantage. Working shifts in a factory by day, and collaborating with AI tools (like GitHub Copilot) by night, I built Nexmy.
Nexmy is a 100% offline-first personal finance app for Android.
What makes it different:
Zero Cloud / Zero Accounts: Your data never leaves your phone. Everything is locally encrypted.
BNPL & Split-Payment Tracking: Perfect for managing installment services like Klarna and PayPal.
Smarty (Beta 1.0): A lightweight, on-device AI assistant that answers your financial questions locally without internet.
Simulators & Tools: Compound interest, mortgage amortization, and clean local PDF reports.
I built this out of pure necessity to regain my own peace of mind, and we just wrapped up our Product Hunt launch. Now, I want to share it with this community.
Nexmy is completely free with no ads. I would be genuinely honored if you tried it out and gave me your raw, honest feedback or feature ideas!
