CloudMagic is the free iOS app for the CloudMagic personal search service from Webyog. CloudMagic indexes your Gmail, Google Apps documents, contacts, calendar entries, and Twitter posts. Once you create an account at the CloudMagic Website via the app, you can add the various services you want to be indexed (and searchable) by CloudMagic. You don't actually give CloudMagic your login ID; instead, CloudMagic uses the Oauth service to allow access to some of your data. You can revoke access at will via the app's Settings.
Your index is stored in the cloud, on CloudMagic's servers (hence the need to create a free CloudMagic account). After indexing, which for my very large archive of email and a number Google docs took mere minutes, you can search for partial words as well as phrases. There's a service selection form accessed via an icon on the app's search field that allows you to select a specific service or media to search, or you can elect to search "Everything." The response time for searches is startlingly fast. (more...)
