Slider fields are a good, mobile-friendly way to ask for numbers without requiring the user to type in.
Slider fields are also an excellent choice for NPS surveys. You can ask users to rate a topic on a scale. You can pick any scale (eg. 0 to 10, or 23 to 789).
Slider fields also allows a range setting which allows your users to select a range instead of a specific number.
You can set the min and max points on the slider scale, set prefix and suffix, the step count, and choose the range option.
