How do I choose?
- Keep the app you already use on iPhone — Most watch apps work together with the iPhone app. First check whether your current to-do app has a watch app.
- Check things off from your wrist — Make sure the watch screen shows today’s tasks and lets you complete them.
- Add tasks by talking — With Talk to Aria on the Aria watch app, you say one line and Aria on your paired iPhone organizes it.
What can the Aria watch app do?
The Aria watch app works together with Aria on your iPhone. Your paired iPhone needs Aria installed, and you do not sign in separately on the watch.
- Today — See today’s tasks and tap the circle to complete one.
- Events — Read today’s events in time order.
- Routines and focus — Follow a routine step by step and use the focus timer.
- Record — Leave a voice memo and your iPhone transcribes and organizes it.
- Talk to Aria — Say one line, your iPhone’s Aria handles it, and the watch shows a short reply and what was added.
- Complications — Put Today (tasks left) and Talk to Aria on your watch face.
What about the other apps?
Reminders and Calendar (Apple), TickTick, Todoist, Things 3 and Fantastical all list Apple Watch among supported devices on the US App Store. What each can do on the watch differs, so read each app’s App Store description. For iPhone-side comparisons, see Best calendar apps for iPhone.
