DueKeeper: Budget Tracker

"When is that payment due again?"

DueKeeper takes the guesswork out of managing your money. It's a household budget app that organizes your income and expenses so you can see exactly when, where, and how much you need to pay — all at a glance. Designed to be intuitive enough for first-time budgeters.

Payment Schedule

• View all your upcoming payments in a clear date-by-account matrix. See which account is being charged, when, and how much. Payment dates that fall on weekends or holidays are automatically adjusted.

Payment Reminders Get notified 1 to 7 days before a payment is due. Never miss a credit card charge or forget a transfer deadline again.

3 Expense Types for Detailed Tracking

• Fixed: Rent, insurance, subscriptions — recurring expenses with a set amount
• Variable: Utilities, credit cards — recurring expenses where the amount changes
• One-time: Travel, appliance purchases — expenses that occur only once

Set payment dates, accounts, and billing cycles for each to get a complete picture of your finances.

Monthly Summary & Charts

• Review your income, expenses, and balance month by month. Category breakdowns and a 6-month trend chart help you spot spending patterns.

Widget Support

• View your income/expense summary and payment schedule right on your home screen.

Multiple Budgets (Premium)
