About the iPhone & iPad revenue estimate
Our estimate of what people in the United States paid inside Microsoft Defender: Security through the App Store during September 2026: in-app purchases and subscriptions, before Apple's commission.
This is not the app's whole revenue. Its developer sells its own ads, often most of what the app earns, and that ad revenue is not included. Neither are payments made outside the App Store.
We expect the real figure inside the full range about 8 times in 10, and inside the darker part, $43K–$390K, about half the time.
