Settings, then How to use, has a picture of every page.
Each week
The line at the top is about how much you can spend on shopping each week from today. It is what the month ends with plus the shops still to come, spread over the days left. With fewer than 7 days left, it shows that amount for those days. Beside it is what is left at the end of the month once every shop and standing order is taken.
The graph is the balance through the month. It falls on a shop date, including a shop still to come, and on the day a standing order leaves. Income raises it on its date, including a date still to come. A debit-card expense lowers it on its date. A cleared shop is already taken off. The dot is today.
Each cart that counts this month has its own coloured line. The month’s shopping money is what is left at month end plus every cart. Each cart gets a share of that for the days it covers, up to the next cart or the end of the month. Green means the cart is under its share. Red means it is over. The Unders and Overs add up to what is left at month end. Tap the line to open that cart on the Shopping List, where you can add or remove items.
Income
Tap Income to add money that changes from month to month, and set the date it arrives. The graph rises on that date, including a date still to come this month. A later month stays out until the 1st. On the 1st, the list is cleared.
Standing Orders
Tap Standing Orders to add a regular payment, and set the day it leaves your account. If that day has already passed, it starts next month.
The total on the Standing Orders page is every order. The amount on the Budget page is only what counts this month. Standing Orders stay each month.
Debit Card
Tap Debit Card for card spending. Each cart is listed there with its name and shop date. Tap it to open that cart. Add any other card expense, such as fuel, and set the date it leaves. The graph falls on that date, including a date still to come this month. A later month stays out until the 1st.
The amount on the Budget page is what counts now. On the graph, a cart falls on its shop date, including a later date this month. A cart dated for a later month shows the 1st of that month and stays out until then. On the 1st, the added expenses are cleared. The carts stay.
Paid
Paid is money already taken off the balance, from shops you have cleared.
New month
New month clears Paid, and sets income amounts back to £0.00. Standing Orders stay. The shopping cart stays as it is.
