Tired of using spreadsheets for tracking your bills? Or maybe you have all of your bills in a to-do app that's not designed for bill tracking... Do you sometimes forget that a bill is due until it's already overdue? That's where What's Due comes in! Never forget about your upcoming bills again with this easy-to-use app. Some of the top features: - Projected Occurrences: Show the next occurrence only... Or turn on the 'Include Projections' filter to include projections up to a year out. - Income & Bills: Add all your income and bills to track everything in one place. - Pay Periods: Group upcoming bills by pay period instead of by month, so you can see what each paycheck needs to cover. - Calendar: See your month at a glance — a month grid marking the days income and bills are due, with each day's list one tap away. - Charts (premium): Visualize your bills and income with category, account, and trend charts — including your on-time payment rate and year-over-year comparisons. - Search: Quickly find any income or bill with the dedicated Search tab. - Widgets (premium): Add widgets to your Home Screen to see and update your bills without opening the app. - Unlimited Bills (premium): Track all your bills (premium feature) or up to 5 upcoming bills at a time without upgrading. - Bill Reminders: Never forget to pay a bill with bill reminder notifications. - iCloud Sync: Automatically syncs with your iCloud, so you can start on your iPhone and continue on your iPad, Mac, or Apple Vision Pro. - Quick Actions: Swipe right to mark as paid or scheduled (paid, but hasn't cleared your bank yet) and left to delete an income/bill. Long pressing a bill with a 'Bill Pay URL' added will allow you to quickly pay online. - Import/Export CSV (premium): Import your bills from a CSV file. Or export them to save outside the app. - Biometrics: Hide your bills from prying eyes by locking them behind biometrics. - Alternate App Icons: Personalize your app with alternate icon options. - Accent Colors (premium): Set your favorite accent color to be used throughout the app. - Multilingual: Use What's Due in English, Spanish (español), French (français), Italian (italiano), Portuguese (português), or German (Deutsch).
