About

Zentaps is a tiny JavaScript module which automatically removes the 300 miliseconds tap delay on iOS devices.

Features:

• Taps take less than 15ms instead of 300ms.
• Supports iOS Safari and browsers in iOS apps.
• Support for old Android browsers (2.3+) is coming later.
• Support for Windows Phone is coming later (if needed).
• Support isn’t needed for Chrome which already fixed the 300ms tap delay. (I wish Apple would do the same. The double-tap zoom & double-tap scroll are relics of the past.)
• Support isn’t needed for browsers that don’t support touch events (e.g., desktop browsers without touch screens).
• 442 bytes minimized & gzipped.

Zentaps observes touch events in the background. If there is no click event in a timely manner (that is, within 10ms) then Zentaps fires a click event and kills the ghost click that comes after 300ms. Of course, if the browser fires the click within 10ms (e.g., when you tapped a little bit longer on iOS) then Zentaps doesn’t have to do anything.

Install

Download Zentaps and include it into your page. A good place is at the very bottom, just before the closing </body> tag. For example:

    ...
    <script src="zentaps-min.js"></script>
</body>

There is nothing else to do. Zentaps automatically detects touch-capable browsers that need a speed-up.

You can also use npm to install Zenscroll:

npm install zentaps
