Some notifications on my Apple Watch (e.g. Viber) use a haptic tap when they appear on my Apple Watch. Others (e.g. Facebook) do not. What determines whether a haptic tap is used or not? Is this something I can change?
There are variations. The 3rd party app developers have some control over what you get, but they won't have been able to check it before launch - they'll have been using a simulator.
This can currently not be changed by the user.
To turn haptic feedback of:
Open the Settings app.
Scroll down and tap Sounds & Haptics.
Turn Haptic Alerts on or off.
What determines whether a haptic tap is used or not? Is this something I can change?
There are two types of haptic feedback:
- System provided
- Application provided
This means that in addition to the ones provided iOS, app developers can implement haptic feedback as they see fit.
Looking at Apple Developer's Human Interface Guidelines, it states:
Some system-provided interface elements, such as pickers, switches, and sliders, automatically provide haptic feedback as users interact with them. Your app can also ask the system to generate different types of haptic feedback. iOS manages the strength and behavior of this feedback.
Can you (the end user) enable this manually? Not unless the haptic feedback was implemented by the developer and gives you the option to selectively disable. From a system-wide perspective, you can only enable or disable all of them.
Not all devices support the full range of haptic feedback, and people can disable the feature entirely in Settings if they choose.
