Any way of checking what apps were used at what time on iphone?

I gave my phone to my friends to keep on him whilst playing football. I think he went on my phone during that time. Is there a way to check what apps were opened/ used during this time.Eg on macs/pcs you can check on logs what time a program was used etc.

There isn't a way to find out what time apps were opened. But if you double tap the home button it will bring up the multi tasking bar which shows what apps are currently running in the background. Which is also in order from newest (left) to oldest (right).

No sadly there's no way you can do that, I've asked apple myself about that before and they said no due to privacy problems they have faced before. I'm sorry about that but you can double click the home button and see the last four opened apps. Hope I helped xxxx
