What database viewer to use for CouchDB?
There is built-in web application that allows you to manage CouchDB instance -- http://guide.couchdb.org/draft/tour.html#welcome
And your question is very ambiguous. You ask for the web application as option but without "a classic browser" you cannot use it.
In case you don't find Futon very intuitive, please checkout CouchDB Query Explorer. The tool is aimed at providing an intuitive approach to configure & use. Define your own fields & filters. Querying is as simple as selecting one or more filters. For more information please visit here
