How we grade them
| 2.8GPACOL ReminderGood | 2.6GPADueGood | |
|---|---|---|
| Value for money | BA donation unlocks four extras, and adding reminders from a browser needs a subscription. The site publishes no prices for either. Google Play only shows a range of $0.99 to $19.99 per item. Hard to judge what you can't see, so a B. | A$7.99 once covers iPhone, iPad and Apple Watch, and the Mac app is another $14.99. Both together cost about what six months of a typical to-do subscription does. Features released after your first year need an optional Upgrade Pass, $4.99 a year on iOS, and anything unlocked stays if you stop. |
| Free plan and trial | AThe app is free to use, with text, phone call, parking and birthday reminders and Google Drive backup. Most people could stay there. Location reminders, the widget, the full repeat options and priorities wait behind a donation. | FNothing is free. Due is a paid download with no free version and no trial, so the $7.99 comes before you've set a single reminder. |
| Features | BIt only does reminders, and it does them properly: one-tap call reminders, a parking countdown, birthdays warned days ahead, and place-based alerts with a range you pick. There are no lists, projects or subtasks, which is on purpose. | BIt does one job, reminders, and does it fully. Auto Snooze re-notifies you every 1 to 60 minutes, 5 times by default and up to 10. Preset buttons postpone in a tap, repeats get as fussy as the third Wednesday of each month, and timers are reusable. But it's reminders and timers, not lists or projects. |
| Ease of use | BThere's no App Store rating to go on, since it isn't on iPhone. It's an app you install and use: pick a reminder type, set the time, done. Backups to Google Drive can run by themselves. | A4.7 from about 2,800 App Store ratings. Type or dictate "at 9am tomorrow" and it offers that as the due date. There's no Due account to set up, and reminders fire without an internet connection. |
| Platforms and integrations | DAndroid only, with a Wear OS companion for your watch. The browser page isn't a separate app. It just sends reminders to the phone, and it needs both the app and a subscription. | CiPhone, iPad, Apple Watch and Mac, synced through your own iCloud or Dropbox, plus Siri. All Apple. The Watch app is a companion that needs the paired iPhone, and the Mac app is a separate purchase. |
