ChatGPT's mobile app growth may have peaked, according to a recent analysis of download trends and daily active users by Apptopia. The analysis reveals that new user growth, measured by percentage changes in global downloads, slowed after April. While ChatGPT's mobile app still boasts millions of daily downloads, the stagnation in growth suggests a potential slowdown in its overall expansion. This could be attributed to increased competition and changes in the AI model's characteristics. Furthermore, the average time spent per user in the U.S. has decreased by 22.5% since July, and the average sessions per user are down by 20.7%. This indicates that U.S. users are spending less time in the app and opening it fewer times per day. However, Apptopia notes that these trends were already present before the rise of Google's Gemini, which has since topped the app charts. The analysis suggests that the experimentation phase with ChatGPT may be over, and users are now incorporating it into their daily routines. For OpenAI, this means the company needs to invest in app marketing or introduce new features to boost user engagement, as novelty alone can no longer drive growth.
