I have an iPhone 5 S with 32 gb, it works fine and has storage but should I get the iPhone X?

I just have pictures and around 50 apps. Should I keep up with the times?

That's really up to you. If you are fine with your 5s (& it should be updated for at least 1 more year) then by all means.

Why waste $1,000 now when you could get that same phone in a year for half the price?
