Turn to the one you need and tap Start. In Rotate view, the cards move with gravity. If you’d rather not turn your phone, switch Timer View to List and pick from all four timers on one screen. ◆ Timer sets for every routine Save up to 10 sets for studying, cooking, workouts, and more. Each set holds four timers. Swipe left or right to jump to the set you need. ◆ All four at a glance on big screens On wider screens, such as iPad, all four timers appear on one screen. No turning needed. Just tap Start on the timer you want. ◆ Start right from your Home Screen Tap a timer in the widget to open the app and start the countdown. Each widget can show its own timer set. ◆ Check and control it from the Lock Screen See the time left on the Lock Screen, and pause, resume, or stop without opening the app. On iPhone models with the Dynamic Island, you can check and control the timer there too. ◆ Make every timer your own Name each timer, set its length, and change the screen and border colors.

Verdict
The clearest difference is in-app purchases: 壁纸美图 at none against Timer4's 1. 壁纸美图 also leads on iOS requirement (15.0 vs 26.1). Timer4's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price and device support there is nothing between them.
