Exoplanet Guide is probably the most complete exoplanet data reference for Android phones.

It is based on the database published by the Planetary Habitability Laboratory @ UPR Arecibo.

Planets for which sufficient data is not currently available (such as missing mass or semi-major axis) are filtered out, but may show up with future database updates. The database can be updated online.

One of the key features is the graphical representation of the habitable zone of a parent star. Exoplanet Guide comes with a fully featured star chart plotting stars down to magnitude 6.4 plus all Messier objects!

Export all exoplanets with illustrations to KMZ format for use with Google Sky (part of Google Earth for the desktop) and explore with the convenience of a larger screen.

The Kepler Field of View overlay changes automatically with Kepler's seasonal rotation (subtle changes, though).
