old iphone useless without ios11 - is there any so

I had my phone stolen a few days ago and have been given a second-hand iphone 5c.

I then discover that basically every app requires ios11 or later - and that ios 11 is not available for the 5c. Am I really limited to only the apps that come with the phone? Or is there some kind of workaround here?https://sarkariresult.onl/ Mobdro  https://192168ll.onl/
