Why I Built a 100% Ad-Free, 3-Second Daily Expense Tracker PWA (React + Firebase + GitHub Actions) published: true

Most "free" expense trackers are bloated with loan ads and slow forms. Here is how I built a lightweight, ad-free PWA with automated 11:00 PM IST email audits.

Most "free" expense tracking apps on the Play Store and App Store share the same problem: bloat and ad spam.

You open the app just to log a ₹20 cup of chai or a ₹150 auto ride, and you are hit with full-screen personal loan banners, credit card pop-ups, and multi-step forms. After three days, you stop logging altogether.

To solve this for my own daily spending, I built Daily House Expense Tracker Pro—a lightweight, 100% ad-free Progressive Web App (PWA) designed to log micro-spends in under 3 seconds and send an automated summary email every night.

What Makes It Different?

1. Zero Ads, Zero Loan Spam, 100% Free: Built purely as a utility tool at Zunaro Labs. No trackers, no banner ads, and no forced bank-account linking.
2. 3-Second Micro-Spend Logging: Open the PWA from your home screen, enter the amount and category (Chai & Snacks, Groceries, Transit, Utilities), and save immediately.
3. Automated 11:00 PM IST Nightly Email Ledger: Every night at 11:00 PM IST, an automated job reconciles your daytime inflows and outflows and emails a clean daily statement straight to your inbox.
4. Installable PWA (0MB Bloat): Works directly in Chrome or Safari and installs to your mobile home screen like a native wallet app.
5. Instant Financial Statements: Filter between variable daily habits and fixed monthly overheads, and export clean reports whenever you need them.

The Tech Stack & Architecture

I kept the stack lean so the app loads in under a second on mobile networks:

• Frontend: React + Vite + Tailwind CSS
• Authentication & Database: Firebase Auth (1-click Google Sign-In) & Cloud Firestore for real-time sync
• Hosting: Firebase Hosting
• Automated Nightly Audits: GitHub Actions cron workflows (11:00 PM IST daily cutoff reconciliation & email dispatch)

What's Next?

I am currently rolling out improvements based on early user feedback—including faster category shortcuts and monthly surplus visual breakdowns.
