Sidetap is a simple and lightweight (2kb minified, gzipped) framework for creating mobile web apps.

The framework actually focuses on providing a flexible side-navigation similar to the one we know from Facebook's mobile app, and, once the navigation part is solved, it is pretty easy to build a simple mobile web app.

It works by telling Sidetap "the content element to be animated". It takes care of clearing the stage using whatever animation is appropriate for the situation.

There are 4 animations offered for displaying the sidebar: upfrombottom, downfromtop, infromright, infromleft. Also, a callback istriggered when the switch is complete.

jQuery UI, the widgets library of jQuery, doesn't ship with support for touch events in any of its widgets and interactions.

Touch Punch is a small hack which brings touch events to the library by using simulated events to map touch events to their mouse event analogs.

It is a plug 'n' play solution, just insert the file into your web pages and there is nothing more to setup.

The hack works in all the widgets and in most scenarios, however, considering it is a simple hack, make sure you test any complex usage.

It is formed of 3 parts: the Countly server + frontend, iOS SDK and Android SDK.

With an event-driven system, almost every action can be tracked including in-app purchases, when a user closes the app, ad-click behavior, etc.

All these details are displayed in the slick interface of Countly. And, you are not limited to racking a single app. The same interface enables adding any number of apps.

Hammer.js is a JavaScript library for adding touch gestures support to any website so that users can interact with them easier on touch devices.

It requires jQuery, only 2kb sized and supports tap, double tap, hold, drag and transform.

• every touch event performed on that element returns a callback with an array of details including:
  • event
  • position
  • touches
  • scale
  • rotation

For drag gestures, it can also return extra info like the angle, direction and distance.

Hammer.js works -almost- on all modern browsers and, to sum up, "you can touch this" : ).
