Apple is punishing its rival for breaking its developers' policy, and comes a day after it took the same action against Facebook.
The move came after both firms used special access for market research.
“We’re working with Apple to fix a temporary disruption to some of our corporate iOS app,” Google said.
After more than 24 hours of disruption, Facebook had its access restored on Thursday.
"We are in the process of getting our internal apps up and running" a spokeswoman told the BBC. "To be clear, this didn't have an impact on our consumer-facing services."
