Amphetamine is an app that prevents Macs from going into sleep mode. It’s been in the app store since 2014, and has nothing to do with drug use. The company reversed its decision, and the app will be able to stay up with its current name and logo.

Gustafson says Apple contacted him on December 29th and told him amphetamine’appears to promote inappropriate use of controlled substances’.

Free MacOS app has been downloaded more than 432,000 times, with a 4.8 rating. Apple even featured amphetamine in an Mac App Store story.

Apps that encourage minors to consume any of these substances will be rejected. Aiding the sale of marijuana, tobacco, or controlled substances (except for licensed pharmacies) is n’t allowed.

Amphetamine does n’t do anything, says Gustafson. Amphetamine’s name would have ruined brand recognition, he says. Amphetamine could make it harder for users to find future updates.

Apple typically hews pretty closely to its app store rules in most cases. The company has faced pushback from developers on several fronts.
