I built an offline-first Expense Tracker & Secure Notepad using Firebase

Hi DEV community! 👋
​As an indie developer, I love building things that solve my own daily problems. I was frustrated with the current market of expense trackers and to-do list apps. Most of them are filled with ads, have cluttered UIs, or lack basic privacy features.
​So, I decided to code my own solution: Easy Note & Expense Tracker.
​🛠️ The Tech Stack & Features
​I wanted the app to be blazing fast and secure. Here is what I focused on:
​Firebase Realtime Database: For instant cloud syncing across devices.
​Visual Analytics: I used HTML/JS libraries to generate dynamic doughnut charts for expense categorization.
​Item-Level Security: Instead of locking the whole app, users can lock specific private ledgers or text notes with custom passwords.
​💡 The Challenge
​The biggest challenge was making sure the UI remains absolutely minimal while holding 4 different modules (Finance, Notepad, Tasks, and Ledger). I stripped away all unnecessary menus to keep the focus purely on productivity.
​🚀 Try It Out
​I just launched the web page for the ecosystem. I would absolutely love to get some feedback from fellow developers on the UI/UX and the overall concept.
