Google has launched the Gemini app on the iPhone. You can now download it on the Apple App Store for free. Some features you'll get include access to "free-flowing conversation" with Gemini Live, allowing you to talk to Gemini conversationally. You can pick from 10 distinct voices, and it supports 10 languages with a promise of more coming soon. Google says this Gemini Live experience is new for iPhone users.
The app also helps students study better with its ability to create tailored study plans and ask it to quiz you. You also get access to Imagen 3, Google's image generation model. You can check this link to see if you have access to it already.
