Good afternoon, everyone, and thanks for joining us. Today, we're reporting revenue of $117.2 billion for the December quarter. We set all-time revenue records in a number of markets, including Canada, Indonesia, Mexico, Spain, Turkey, and Vietnam, along with quarterly records in Brazil and India.
As a result of a challenging environment, our revenue was down 5% year over year. But I'm proud of the way we have navigated circumstances, seen and unforeseen, over the past several years, and I remain incredibly confident in our team and our mission and in the work we do every day. Let me discuss the three factors that impacted our revenue performance during the quarter. The first was foreign exchange headwinds, which had a nearly 800 basis point impact.
On a constant currency basis, we grew year over year and would have grown in the vast majority of the markets we track. The second factor, which we described in a November 6th update with COVID-19-related challenges, which significantly impacted the supply of iPhone 14 Pro and iPhone 14 Pro Max and lasted through most of December. Because of these constraints, we had significantly less iPhone 14 Pro and iPhone 14 Pro Max supply than we planned, causing ship times to extend far beyond what we had anticipated.
Production is now back where we want it to be. The third factor was a challenging macroeconomic environment as the world continues to face unprecedented circumstances from inflation, to war in Eastern Europe, to the enduring impacts of the pandemic. And we know that Apple is not immune to it. But whatever conditions we face, our approach is always the same.
Revenue came in at $65.8 billion for the quarter, down 8% year over year. However, on a constant currency basis, iPhone revenue was roughly flat. Our customers continue to rave about the astounding camera capabilities and unprecedented battery life and the groundbreaking suite of health and safety features. The iPhone 14 lineup pushes the limits of what users can do with a smartphone.
During the quarter, Mac revenue came in at $7.7 billion, which was in line with what we had expected. We had a difficult compare because this time last year, we had the extremely successful launch of the redesigned M1 MacBook Pros. We also faced a challenging macroeconomic environment and foreign exchange headwinds. We remain confident in and focused on the long-term opportunity for Mac.
During the quarter, iPad revenue grew 30% to a total of $9.4 billion. The very strong growth was due in part to a favorable compare to the December quarter a year ago when we experienced significant supply constraints.
Revenue for Wearables, Home and Accessories was $13.5 billion, which was down 8% year over year driven by foreign exchange headwinds and a challenging macroeconomic environment. We remain excited about the long-term opportunity in the category.
We continue to hear wide praise for Apple Watch Series 8 and Apple Watch Ultra, which has set a new standard for what's possible with the wearable. From a whole host of health and safety features to incredible new capabilities for extreme athletes, there is something for everyone in these amazing products. Customers are excited about some phenomenal new features we've made available across many of our products as well. One of the highlights is emergency SOS via satellite, which launched for iPhone 14 customers in the U.S. and Canada in November and for customers in France, Germany, Ireland, and the U.K. in December. This is a feature we hope our users will never need, but it is incredibly heartening to get emails from people describing the life-saving impact our new safety features have had on them. We're always looking for new ways to empower people to create and collaborate.
Today, we are very excited to announce that we've achieved a truly incredible milestone. Thanks to our deep commitment to innovation, incredible customer loyalty and satisfaction, and a large number of switchers, we now have more than 2 billion active devices as part of our growing installed base, double what it was just seven years ago.
This is an incredible testament to our products and services and the strength of our ecosystem. We set an all-time revenue record of $20.8 billion in services, which was better than what we had expected.
We achieved double-digit revenue growth from App Store subscriptions and set all-time revenue records across a number of categories, including cloud and payment services. All told, Apple now has more than 935 million paid subscriptions.
