10. Bump And Run
Google got Bump, a social sharing app that allows smartphones to share files and information by literally bumping devices, when it acquired the company of the same name last September for an undisclosed sum; an AllThingsD report put the acquisition at least $30 million.
After the Google acquisition, Bump co-founder and CEO David Lieb said the company's applications, Bump and Flock, will "continue to work as they always have for now." For now was short-lived. In a Dec. 31 blog post, Lieb announced that as of Jan. 31 both Bump, which has been downloaded more than 100 million times, and Flock, a photo sharing app, "will be removed from the [Apple] App Store and Google Play. After this date, neither app will work, and all user data will be deleted."
"We've taken much care to make sure that you can retain any data you have in Bump and Flock," continued Lieb. "At any point in the next 30 days, simply open either app and ... follow the instructions for exporting your data."
