The native HTML spinner does not really work on a mobile device (e.g. in safari browser). I need a spinner that will work as a spinner on a mobile device.
I don't know if Bootstrap has one that would look good. At least the jQueryUI spinner look half-decent in the browser.

UPDATE. As far as what you said that spinners are bad UI. IMHO the spinner that allows you to enter a value, as well as select one by spinning, is the best. If you look at a native iOS app (and I have one for my product), the numbers are entered using a spinner. I am trying to emulate this behavior in the web app.
