How do I use pon on the Apple Watch?

On the Apple Watch you have your lists right on your wrist: check off items, see the store-grouped order, and get the „Nearby“ hint — handy when your iPhone stays in your pocket. A complication on the watch face gets you into your list with a single tap.

The order and everything learned come from the iPhone; the Watch mirrors them and syncs up when your iPhone is nearby. Open the Watch app once with the iPhone in range so everything syncs freshly.
