iPhone app developers questioned by US investigators as a part of Apple antitrust probe

The US Justice Department has reached out to app developers as part of its investigation into Apple Inc, one of the four big tech companies being probed for alleged anti-competitive behavior, according one of the developers and another person familiar with the investigation.The chief executive of developer Mobicip, Suren Ramasubbu, told Reuters he was interviewed in November by a US investigator who asked about the company's interactions with Apple. The app, which has nearly a million users worldwide, allows parents to control what their children see on their iPhones.Ramasubbu said the Mobicip app was temporarily removed from the iPhone app store last year for a failure to meet requirements imposed by Apple.[caption id="attachment_7889121" align="alignnone" width="1024"]

Apple was accused in lawsuits last year of abusing its clout in the app market.

The company was accused in lawsuits last year of abusing its clout in the app market. In one case, the US Supreme Court gave the go-ahead last May to an antitrust lawsuit that accused Apple of forcing consumers to overpay for iPhone software applications.

Screen time control

Apple introduced its Screen Time app, which includes parental controls, in June 2018. At the start of 2019, Ramasubbu told Reuters, his company was contacted by Apple and warned that Mobicip's app violated the iPhone-maker's rules relating to technical elements that had previously been acceptable.The app was removed from the app store for about six months, during which time it was updated to be compliant with Apple rules, Ramasubbu said. It was reinstated in October 2019, but he estimates his company's business has shrunk by half.Six executives of parental control app companies interviewed by Reuters said they had a comfortable relationship with Apple until mid-2018. That is when Apple introduced its own, similar software giving parents oversight of their children's phone screen time and searches.Apple has said that it had been concerned about parental control apps using technology which gave developers access to sensitive data, and that they declined to approve apps that used the technology if they did not also commit to not sharing data on children.As the arbiter of who is allowed to sell in the app store, Apple says it has the power to ensure that only the highest quality apps are sold there.But some developers say it also allows Apple to push out apps that compete with its own products, thus strengthening its profits at a time with its device sales have stagnated and it is seeking new sources of revenue.
