Facebook Home may have been downloaded more than 500,000 times in its first week but new research from BTIG suggests that it could take significantly longer to get its next 500,000 downloads. Using data from AppAnnie, BTIG found that Facebook Home’s ranking in the Google Play charts peaked at No. 50 on April 19th before quickly declining to No. 130 less than a week later. While Facebook debuted its Home application to great fanfare earlier this month, the app has been poorly received by many Android users who have been bombarding it with one-star reviews that account for more than half of all its total reviews on Google Play. BTIG says that because Facebook plans monthly updates to Home, it stands a chance to reboundÂ if it can improve the user experience.
