You pay for Netflix, rent, insurance, gym, cloud storage — more than you think, on repeat. Each one feels small. The total rarely does. Duly puts every recurring payment in one place and nudges you before each one hits. Add an expense, pick how often it repeats (weekly, monthly, yearly, or any custom interval), and get a reminder before it's due. Mark it as paid right from the notification — no need to even open the app. The home screen shows what's coming up and how much you're spending this month. Widgets bring the same view to your home and lock screen. Built-in analytics break down your recurring payments by category and project totals months ahead. Works with any currency — amounts auto-convert to your base currency. Organize with custom categories. Add expenses through Siri. Syncs across your Apple devices via iCloud. Available in 21 languages. That's it. No budget planning, no bank linking, no account sign-ups. Just your recurring payments, where you can actually see them. Free for up to 6 expenses. A single purchase removes the limit. No subscription required to track your subscriptions. Your data stays on your device and in your iCloud. Nothing leaves your hands.
