Flipper is an iPhone MySQL client. While not intended as a full desktop SQL development environment, it does enable the user to write complex queries and submit them over the network to MySQL databases.

In addition to the basic ability to write and submit queries Flipper also has the ability to query a database and pull back the entire schema, loading the results into iPhone resident flash memory. This allows you to reference the databases schema without the need to make additional connections or hold open a connection while writing new queries.
