Moondane is a simple, private expense tracker. Log what you spend in seconds and see where your money goes. No bank login. No account. Your expenses stay on your device and in your own iCloud. YOUR OVERVIEW One screen shows your latest transactions, what you spent this month, what is left, your budgets and the renewals coming up. QUICK TO LOG Amount, date, category, done. No setup and no ads. SIRI AND SHORTCUTS Say "Log an expense in Moondane" and Siri saves it without opening the app. Siri asks for the amount and the category, then shows you the expense. You can undo it. Every Siri action is also a Shortcuts action. Put Log Expense on your Lock Screen, on the Action button or in a shortcut of your own. Quick Log reads one sentence, so "12 on groceries yesterday" is a whole expense. With Apple Intelligence, your device reads the sentence itself. KNOW YOUR PACE Spent this month shows where the month is heading. Your typical month, based on your own history, shows what normal looks like for you. Charts show your cash flow, your monthly totals and how each category compares with a typical month. BUDGETS Set a budget for any category, for a month, a quarter or a year. Moondane tells you when you are heading over. SUBSCRIPTIONS See your recurring payments and the renewals coming up. With Premium, see what you pay each month, a calendar of renewals and the cost by category, and spot the services you stopped using. TAGS Tag expenses across categories to answer questions like "How much did that trip really cost?" WIDGETS Keep what is left this month, your month pace, the week, upcoming renewals and a budget on your Home Screen and Lock Screen. Add an expense from Control Center. iPHONE DUO AND iPAD On iPhone Duo, your cards spread out across the large display. On iPad, they fill the window at any size. PRIVATE BY DESIGN Your data stays on your device and syncs through your own iCloud account. It does not count against your iCloud storage. No servers, no logins, no tracking, nothing to sell. Moondane works fully offline. YOUR DATA STAYS YOURS Import from CSV and export at any time, in a format you can open anywhere. Moondane is free to use.
