I bought an Apple Watch Series 9 four weeks ago, and I was expecting double tap will brings a lot of convenience to me. But sadly in reality, double tap has lot of limitation and the UX is a mess.
- Double tap to play/pause or skip songs are only available in Apple Music app and Now Playing. However, Apple does not make API for double tap publicly, the double tap function is completely useless in YouTube Music and Spotify. The only workaround is switch to Now Playing.
- If any notification has only "Dismiss" button, the double tap is useful. However, if the notification, such as WhatsApp or Telegram notification, contains "Reply" button and it is located in the first place, it directly directs you to reply. I was attempting to have continuous double tap twice, but it won't work.
- It's hard to trigger double tap very often even you wear your watch tightly and tap your fingers firmly.
- Lack of the ability to customise the double tap. You only have two usage: playback and smart stack.
The double tap sounds like a last min attempt by Apple to add a new feature by just slightly modifying the accessibility feature.
