How to install aakash app?

Excuse me, could you possibly guide me through the steps required to install the Aakash app? I'm rather new to the cryptocurrency scene and find it challenging to navigate the installation process. Is it available on both Android and iOS? If so, could you elaborate on the specific steps for each platform? Additionally, are there any pre-installation requirements that I should be aware of? Such as minimum operating system versions or necessary permissions? Your assistance in this matter would be greatly appreciated.
