Duesday brings subscriptions, everyday spending, monthly budgets, and savings goals into one place. SEE YOUR MONTH Set a monthly budget and see what remains after subscription commitments, other spending, and savings allocations. TRACK SUBSCRIPTIONS Add common services quickly, enter details manually, or import screenshots of your Apple subscriptions. Duesday separates detected services into drafts so you can review every name, price, billing cycle, and renewal date before saving. RECORD OTHER SPENDING Add purchases and bills in seconds. Your Spending view combines subscriptions with the other entries you record for the calendar month. BUILD SAVINGS GOALS Create savings targets, record progress, and choose how much of the month's remaining budget to allocate to each active goal. UNDERSTAND THE NUMBERS See category breakdowns, upcoming full charges, recurring monthly commitments, billing mix, and goal progress. Duesday keeps different currencies separate rather than applying an undisclosed exchange rate. STAY AHEAD Use local renewal reminders and optional cancellation guidance when you need them. Track cancelled commitments and keep proof notes or screenshots on your device. PRIVATE BY DEFAULT Subscriptions, screenshot drafts, budgets, spending, goals, and proof remain on your iPhone. No bank connection is required. An account is optional and is used only for verified referral rewards and account management. Optional usage sharing helps us improve Duesday’s navigation and features. It starts only if you agree and excludes your financial records. You can change your choice in Settings. HELP WHEN YOU NEED IT Email support or send a feature request directly from Settings. FREE AND PRO The free plan includes 3 subscriptions, 10 other-spending entries per calendar month, and 1 active savings goal. Verified friend referrals can add subscription slots.
