ChatGPT’s mobile app just had its biggest month yet

The launch of OpenAI’s new GPT-4o “omni” model in May has sent ChatGPT’s app revenue soaring. After a big jump following the model’s release, the mobile version of OpenAI’s chatbot has now seen its biggest month of revenue yet. The app pulled in $28 million in net revenue from the App Store and Google Play in July, according to data provided by app intelligence firm Appfigures.

Note that net revenue represents the sum OpenAI keeps after paying Apple’s and Google’s in-app purchase fees. In addition, the firm found that Apple’s App Store accounted for 83% of the app’s revenue — a figure that has grown 20% since June.

Before app store fees, ChatGPT’s app had grossed $28.9 million in May, $34 million in June, and $39.9 million in July.

With GPT-4o, ChatGPT gained the ability to handle text, speech and video. It also began offering faster response times, and the chatbot could be interrupted, making interactions with the AI feel more human-like and natural, among other things.

Demand for this new technology drove ChatGPT app revenue growth up by 40% in May, Appfigures says. And while that growth has slowed slightly since, revenue continues to climb at a healthy pace.

With the revenue the app generated in July, Appfigures estimates ChatGPT saw the addition of 2 million new paying subscribers — another new record for the mobile app.

With the arrival of ChatGPT’s new Advanced Voice Mode, which offers nearly real-time, realistic interactions, Appfigures expects growth to continue in the months to come.
