The Beginning: A Personal Problem
Every month-end felt like a mystery. Where did my money go? Sure, I was using spreadsheets and notes apps, but they were cumbersome and easy to forget. My friend had the same problem – we’d often discuss how we needed something simpler, something that would take seconds to record an expense.
That’s when it hit me: why not build something ourselves?
The Vision
I wanted to create something that would be:
- Lightning fast to use (under 5 seconds to add an expense)
- Mobile-first (because who carries a laptop to record coffee expenses?)
- Simple enough that we’d actually use it daily
- Smart enough to give insights about our spending
The Tech Stack
As a self-taught developer working at a tech startup, I chose technologies I was comfortable with:
- Frontend : Vue.js with Tailwind CSS for a clean, mobile-friendly interface
- Backend : Laravel for robust API development
- PWA Features : Service workers for offline capability
- Database : MySQL for reliable data storage
Key Features
- Quick Add : Add expenses in seconds with smart categorization
- Insights Dashboard : Visual breakdown of where your money goes
- PWA Installation : Install on your phone like a native app
- Offline Support : Add expenses even without internet
- Multi-currency : Support for different currencies
Challenges Faced
Challenge #1: Making It Lightning Fast
The biggest challenge was speed. If it took more than 5 seconds to add an expense, we knew we wouldn’t use it. The solution? A minimalist interface focused on quick input with smart defaults.
Challenge #2: PWA Implementation
Getting the PWA to work smoothly across different devices was tricky. Service workers, caching strategies, and offline support took several iterations to get right.
Challenge #3: User Experience
Making something simple is hard. I went through multiple iterations of the UI, constantly asking:
- Can this be simpler?
- Can we remove this step?
- Is this really necessary?
Real-World Testing
The best part about building this was having immediate feedback. My friend and I used it daily, which led to quick iterations based on real usage:
- Found that category selection needed to be faster
- Added quick shortcuts for common expenses
- Improved the dashboard based on actual needs
Current State and Future Plans
The app (dailyexpensetracker.in) is now live and being used daily. Future plans include:
- AI-powered insights for better financial decisions
- Bank API integration for automatic tracking
- Smart receipt scanning
- Cloud backup for data security
Lessons Learned
- Start Small : Having just two users (my friend and me) was perfect for initial development
- Real Problems > Perfect Code : Solving a real problem is more important than having perfect code
- User Feedback is Gold : Daily usage by real users provides invaluable insights
- Simple > Feature-rich : People prefer simple solutions that work well over complex ones with many features
For New Developers
If you’re just starting out, here’s my advice:
- Build something you’ll actually use
- Start with a small, specific problem
- Launch early, iterate often
- Don’t worry about scaling until you need to
- Focus on speed and simplicity
Try It Out
The app is free to use at dailyexpensetracker.in. I’m actively developing it and would love feedback from the community. Whether you’re a developer interested in the technical aspects or someone looking for a simple expense tracker, feel free to check it out.
Remember, every big journey starts with a small step. This is my first step into building products that solve real problems, and I’m excited to keep improving and building more.
