See what you actually get done. DueView reads your Apple Reminders and turns them into a clear picture of how you work: what you finish, what slips, and when you're at your best. No new list to maintain โ€” it uses the reminders you already keep. WHAT YOU GET โ€ข Completion gauge โ€” one number for how much of your due work you're actually closing. โ€ข An honest on-time rate โ€” unfinished work that has blown its deadline counts against you. Finishing two things promptly while ten sit overdue does not report as 100%. โ€ข Past due at a glance โ€” how many tasks are late, and how long the oldest has been sitting there. โ€ข Average delay โ€” when you are late, how late. โ€ข Tap any stat to see the reminders behind it. Not just "4 overdue" โ€” which four, oldest first, with a jump straight to the Reminders app. โ€ข Per-list breakdown โ€” find out which list is quietly dragging you down. โ€ข Trends โ€” every headline number is compared against the previous period, so you see direction, not just position. DUEVIEW PLUS โ€” ONE-TIME PURCHASE โ€ข Longer history: 1 month, 3 months, 1 year, or all time โ€ข Best Day โ€” the weekday you close the most โ€ข Peak Hours โ€” the time of day you actually finish things โ€ข Custom thresholds โ€” decide how late still counts as on time No subscription. Buy once, keep it. BUILT TO BE HONEST DueView tells you what it can't measure. Tasks with no due date can't be judged for timeliness, and repeating tasks only report their current occurrence โ€” so the app says so on screen, instead of quietly leaving them out of your numbers. PRIVATE BY DESIGN Your reminders are read on your device and stay there. No account, no sign-in, no server, no tracking. REQUIREMENTS DueView works with the reminders already in Apple's Reminders app. It reads them; it never changes them.
