About this app

Duemark reminds you before a bill is due, and keeps everything on your phone.

Add each bill once: its name, amount, due date and how often it repeats. Duemark works out every next due date, reminds you on the day or 1, 3 or 7 days before, at the time you choose, and lets you mark the bill paid with one tap.

UPCOMING
• Overdue bills at the top, in red, so nothing slips
• What is due this week, then everything later
• Tap the round button to mark a bill paid and the next one appears by itself. Changed your mind? Undo.

CALENDAR
• A month grid with a dot on every day something is due
• Tap a day to see its bills

TOTALS
• This month: how much is due, how much is paid and how much is left
• Subscriptions: what they cost you per month and per year

REPEATS THAT GET THE DATES RIGHT
Once, weekly, every 2 weeks, monthly, every few months or yearly. A bill due on the 31st falls on the last day of shorter months (February 28, or 29 in a leap year) and goes back to the 31st when the month has one.

EACH BILL, YOUR WAY
• Optional amount, with your own currency symbol
• 12 categories, each with its own icon
• Notes, and a payment history for every bill

NO ADS. NO SUBSCRIPTION. NO ACCOUNT.
You pay once. There are no ads, no in-app purchases and no sign-in. Duemark never asks for your bank details and never connects to your bank.

WORKS OFFLINE, STAYS PRIVATE
Duemark has no internet permission at all, so it cannot send your bills anywhere. Reminders are scheduled on the phone itself. Moving to a new phone? Back up to a file and restore it there; you decide where the file goes.

ALSO
• Light and dark theme, or the same as your phone
• Large buttons that are easy to tap
• In 12 languages

Duemark is a reminder, not a payment service: it does not pay bills for you.
Bill due date reminders. No ads, no subscription, no account. Works offline.
