What does Apex mobile run on?

Could you please elaborate on the underlying technology that Apex mobile operates on? I'm curious about the platform's infrastructure and the specific software or hardware it relies on to function seamlessly for its users. Is it built on a blockchain framework, or does it utilize a different type of distributed ledger technology? Additionally, are there any specific mobile operating systems or devices that Apex mobile is optimized for, or is it designed to be universally compatible? Understanding these details would help me gain a more comprehensive view of Apex mobile's capabilities and potential limitations.
