My iPhone 5 is up to date. So I can't install any apps. So what can I do? Please help me.

Many apps these days require iOS much more recent than 10.3.4. If the apps you want require iOS 15 or newer then your only option is to buy a newer iPhone.

An iPhone 5 cannot be updated beyond 10.3.4, which is a 32 bit operating system. Most, if not all apps nowadays are 64 bit apps and require a 64 bit iOS version. However, your iPhone 5 is too old to run such, as it is purely 64 bit hardware.

An iPhone 5 isn't capable of 11 or above. Try downloading them to a newer unit on the same Apple ID first.
