Xpenses can tell you when a bill is due and when money is about to run short, so you do not have to open it every day. Everything is in Settings > Preferences.
Payment reminders
With Payment reminders on, each morning Xpenses sends you the bills still unpaid that are due that day, in the wallet you have open. Only bills with a due day can be reminded: give your bills their day.
With Pro, the same switch also sends the low-balance warning: when an account is forecast to go below zero in the next 7 days, you hear about it once, a few days before.
Monthly report (Pro)
With Monthly report on, you get next month's forecast by e-mail a few days before it starts: what will come in, what will go out and what will be left. Each e-mail has a link to stop it.
Notification or e-mail
If you use the phone app and allowed its notifications, reminders arrive as notifications on the phone. Otherwise they come by e-mail. Never both. The monthly report is always an e-mail.
Change the language or currency
On the same screen, Language sets the language of the app, the reminders and the e-mails, and Currency the currency amounts are shown in. Changing the currency does not convert amounts: it only changes the symbol.
