The problem

Google Sheets is great for personal finance tracking on a desktop. On mobile, it's painful. This app puts a fast, phone-native interface in front of your existing spreadsheet so day-to-day logging stays frictionless.

Features

• Log incoming and outgoing transactions in seconds from your phone
• Budget tracking per category, rolling all-time
• Per-subcategory spend breakdown
• Add, edit, and delete entries
• Live sync — all data lives in your Google Sheet

How it works

Google Sheets acts as the database. A Google Apps Script web app is deployed as an HTTP API over the spreadsheet — reads are unauthenticated, writes require a shared secret. The Svelte 5 frontend calls that API directly from the browser and is deployed as a static site to GitHub Pages. No traditional backend server, no infrastructure to maintain.
