Airguide Publications, the publisher of Flight Guide airport guides and the iEFB tablet app, has ceased operations.

Customers with an iEFB subscription were left to wonder about the updates they were owned after the app was pulled from Apple’s App Store.

iEFB is the private label brand of Tampa-based AnywhereEducation’s eKneeBoard app. “There are several thousand Flight Guide iEFB subscribers,” said AnywhereEducation CEO Mike Wilson. “We will do right by the Flight Guide iEFB users.”
