CalculatorAI
Bill Tracker
A monthly checklist: overdue first, then this week, then later — ticked off with the real amount and date
Overdue bills stay red with the late fee at stake until they are paid; nothing is rolled forward behind your back
Bills by paycheck: each bill under the paycheck that has to cover it, and what is left over
Autopay bills tick themselves off; bills that vary expect the average of the last three payments
What a bill tracker has to get right
A monthly checklist
Every bill due this month in one list — overdue first, then this week, then later — and one tap marks it paid with the real amount and date.
Overdue never disappears
A missed due date is not quietly rolled forward to next month. It stays red, with the late fee you set, until a payment is recorded.
Bills by paycheck
Say how often you are paid and every bill lands under the paycheck that has to cover it, with what is left over — the paycheck budget sheet, always current.
Autopay and bills that vary
Autopay bills mark themselves paid on the due date. Electricity, water and card payments expect the average of their last three payments.
Calendar and reminders
Due dates on a month grid and on your workspace calendar, with a reminder a few days before — at the hour you choose, not at 3 a.m.
A shared household book
Keep the rent and utilities with a partner or flatmates: everyone sees what is paid and who paid it, and each person's own bills stay private.
AI Assistant
Ask what is still owed
The site assistant reads the same figures the tracker shows — this month's checklist, what is overdue, the next due dates, the paycheck plan — and answers with your numbers.
What it helps with
Answer 'what is due this week?' and 'what is overdue?' from your own list.
Explain which paycheck covers which bill and what is left after it.
Point out a bill that keeps getting paid late, or a variable bill creeping up.

Considerations & Limitations
- No bank or card connection — a bill is paid when you mark it, not when a statement shows it
