Know what is due before pay day
Most money stress is about timing, not totals. Your pay might cover the month, but if rent, the phone bill and the credit card all land before your next pay day, the account can still dip below zero. This calendar puts every bill and every pay day on the day it happens, so you can see the gaps coming.
How to use it
- Press + Add (or Try it with sample data to see how it works first).
- Choose Bill or expense or Income, then give it a name, an amount, a category and the first date.
- Pick how it repeats: every week, every 2 weeks (handy for pay days), every month, every 3 months or every year. Add an Until date for things that end, such as a loan or a phone contract.
- Click any bill on the calendar to mark it paid, skip just that date (for a month you don’t pay it), edit it or delete it.
- Open Balance, currency and your data and type the money in your account today. Each day then shows what you will have left after that day’s bills and pay. Days below zero turn red.
- Download the month as an image, PDF or Word file to print and stick on the fridge.
What each part shows
- The summary at the top: bills this month, how much you have paid, how much is still to pay, income, and the lowest your balance gets.
- Calendar or List: the calendar shows the month at a glance. On a phone, bills become coloured dots so the month still fits. The list view shows every bill and pay day in date order, with a tick box for paid.
- Coming up: the next 14 days, so you know what to keep money aside for.
- Where the money goes: this month’s bills by category, from rent and housing to “Family back home” for money you send to relatives.
A bill on the 31st falls on the last day of shorter months, so it never vanishes in February.
Worked example
Say you have $1,800 in your account on the 1st. You are paid $2,100 every two weeks, starting on the 1st. Rent is $1,450 on the 1st, the transit pass $156 on the 1st, groceries about $95 every week, the phone $55 on the 8th and the credit card $200 on the 25th. On the 1st your balance goes from $1,800 to $2,294 after pay, rent and the pass. The calendar then counts down day by day, jumps back up on the next pay day on the 15th, and shows you whether the credit card on the 25th is safe. If a day turns red, you know to move a payment or keep some money back.

Questions
Does it connect to my bank? No, and it never will. You type in your own bills, so nothing about your accounts leaves your device.
I used the expense calendar on nihalsulaiman.com. Can I bring my bills over? Yes. In the old calendar press Download backup, then here open Balance, currency and your data and press Restore backup. Your bills, repeats, paid ticks and skipped dates come across. If you locked the old calendar with a passcode, unlock it there before you download the backup.
Can I use rupees, dirhams or pounds? Yes. Pick your currency in the settings. It only changes how amounts are shown.
What is the difference from the budget planner? The budget planner works out monthly totals and savings. The bill calendar shows when each payment happens, so you can plan around pay days.
