Turns out, celebrity power wasn’t enough to keep video-calling app Airtime flying high.

According to third-party data tracker AppData, Airtime had 190,000 monthly active users on July 7. On August 5, the number had decreased by 47% to 100,000 monthly active users. The application has lost 10,000 monthly active users in the last seven days.

The news comes just  a few months after the apps rocky--but star-studded--launch.

Co-founders Sean Parker and Shawn Fanning launched Airtime this June at Milk Studios in New York City. Comedic actors Jimmy Fallon, Julia Louis-Dreyfus, and Joel McHale helped the former Napster co-founders conduct the debut demonstration, and musicians Snoop Dogg and Alicia Keys used Airtime to dial in and address the audience.

Despite the celebrity fanfare, the event was riddled with failure. The product experienced frequent glitches and crashed several times during Parker's initial product demo.

Airtime allows users to video call their Facebook friends, or to connect with an unknown Facebook user based upon shared interests. The latter use drew comparisons to Chatroulette, an Internet service that randomly paired web callers together and garnered significant popularity before fizzling.
