Monthkeep: Fixed Expense Check

Your month does not start on the 1st. It starts on payday. Monthkeep is a fixed expense checklist that runs from payday to payday. Rent, phone, insurance, installments and your salary sit in one list, and you tap the circle when each one is paid. Open it on payday and you see what you still have to pay before the next one. WHAT YOU SEE ON THE HOME SCREEN • Days until next payday • Left to pay this cycle, in one big number • Net cash flow: income minus fixed expenses • Missed items in red, the next 7 days below, then the whole cycle BUILT FOR REAL FIXED EXPENSES • Payday cycle: pick your payday (the 25th, the 15th, the last day) and every list follows it • Weekend shift: if a due date or payday lands on a weekend, move it to the Friday before or the Monday after. The original date stays visible next to it • Installments: set 3, 6 or 12 months and the item ends by itself • Amounts that change: mark utilities or a maintenance fee as "varies" and long-press to set this month's amount only • Account or card and whose it is (me or partner), with filter chips • Undo on every check CALENDAR A month view with expense and income dots, monthly total out, and the list for any day you tap. REMINDERS THAT STAY QUIET The evening before and the morning a payment is due. Set the morning time and quiet hours. Turn reminders off and everything still works. HOME SCREEN WIDGET See what is left this cycle and check off a payment without opening the app. YOUR DATA STAYS ON YOUR PHONE No account, no sign-in, no bank linking, no cloud sync. Export to CSV whenever you want a copy. Monthkeep works like a notebook for the money that leaves every month, minus the forgetting. Add your fixed expenses once, then just check them off each payday cycle.
