To add a Summon Search Box to your web page, you can use the HTML snippet: 
Chalmers Library decided to put coding efforts into other projects then making our own native smartphone app. Instead we decided to go with a "app-service-provider", Widgetbox. We are on the Gold-price-plan, one year subscription 22$/month. Widgetbox allows you to make and distribute a mobile web app with very little effort. You add your own content, HTML and CSS and it gets pushed out into the smartphone app.
We introduced the app in November 2010 and seen good usage since then. We added Summon to the app in January and it being used. The splash screen offers searching in Summon, a link to the ILS (Millennium OPAC for re-newals, etc.) and Today's opening hours. Other screens in the app include our Twitter-feed, RSS feeds for our blogs and New books, Our Facebook account, Map of campus, Contact information and some links to other services that might be of interest. So far the app via Widgetbox has been able to provide us with what we need.
To download the app point your smartphone to http://www.widgetbox.com/mobile/app/chalmerslibrary
Adding Summon to Widgetbox is very straightforward using the HTML snippets available. Here is the HTML for our setup including a link to our Millennium OPAC.
<div style="margin: 15px; padding: 10px 0px; background-color: #ccc; color: #5e5d5d; text-align:center; font-size: medium"; class="content-view grouped"> <div style="color:#00697f; font: normal 1.8em Arial; margin-bottom: 5px;"> Search Summon</div> <form action="http://chalmers.summon.serialssolutions.com/search/results" method="get"> <input name="spellcheck" value="true" type="hidden" /> articles, books & more<br /> <p><input name="q" size="25" type="text" /> <br /><br /> <input class="summon-search-button" value="Discover!" type="submit" /> </form> <br /> <a href="http://chans.lib.chalmers.se/patroninfo/"><img src="http://chans.lib.chalmers.se:2082/screens/app_chans3.png" /></a> </div>
This it what it looks like:
