Pennystack: Expense Tracker

Log an expense in 3 seconds and see how much you can still spend today. Pennystack is a simple expense tracker and budget planner that works without a bank login, without an account, and fully offline.

TAP, TYPE, DONE
Open the app, tap +, type the amount on the built-in number pad, pick a category. Your frequent items ("Coffee 4,500") become one-tap chips on the home screen and in the widget, so daily spending takes seconds, not minutes.

BUDGET THAT STARTS ON PAYDAY
Set your month to start on the 25th, the 10th, or whenever you get paid. The big number on the home screen shows what is left of your monthly budget, and "Today: up to …" tells you how much you can spend today without going over. Get a heads-up at 50%, 80% and 100%.

MONEY MANAGER AT A GLANCE
• Calendar: daily spending under each date, no-spend days counted
• Stats: category donut, 6-month flow, and plain-language insights ("At this pace you'll end the month with … left")
• Accounts: cash, bank and card balances that update with every entry
• Subscriptions and fixed costs logged automatically on their billing day

HOME SCREEN WIDGET
Budget left plus your quick-add chips right on the home screen. Log an expense without opening the app.

REMINDERS THAT DON'T NAG
A short morning summary and an evening nudge only if you haven't logged anything. Quiet hours, sound and vibration are up to you.

PRIVATE BY DESIGN
No sign-up, no login, no bank connection. Every record stays on your phone. Export to CSV anytime, share a monthly summary card with friends, switch between light and dark theme.

Pennystack is the spending tracker for people who tried a complicated budget app and quit. Keep it simple, keep it daily, and watch the pennies stack up.
