‘Nano Banana’ Sends Gemini to No. 1 on App Stores as India Leads the Trend

The company is introducing provenance measures to address privacy and misuse concerns.

Overview

  • Appfigures data shows Gemini hit the top overall spot on iOS from September 10 and on Google Play from September 12, with daily downloads peaking at 414,000 on September 13—a 667% jump.
  • India is the largest market for Nano Banana usage and a driver of growth, with localized trends such as retro saree portraits, 3D figurines, landmark backdrops, and photo restorations going viral.
  • The Gemini 2.5 Flash Image model enables multi‑image fusion, natural‑language edits, and strong likeness preservation, fueling the creation of hundreds of millions of shareable images.
  • Google now places a visible diamond watermark on outputs, embeds SynthID markers, and is testing a detection platform with plans for a consumer checker to identify AI‑generated images.
  • Privacy questions persist as some users report unexpected personalized details in outputs, and Google’s terms allow uploaded content to be used for AI training unless users opt out; watermarks can also be cropped from posts.
