How to use Gemini in mobile?

Hello there, could you please elaborate on how exactly one can utilize the Gemini platform on their mobile devices? I'm quite interested in the steps involved, as well as any specific features or benefits that the mobile version of Gemini might offer. Is there a dedicated app that needs to be downloaded, or can it be accessed through a web browser? Also, how secure is the mobile version in terms of safeguarding user data and transactions? I'd appreciate any insights you can provide on this topic.
