Can you suggest a nice app to block others from getting access to my mails, messages , to do lists etc
Yup passcode lock your phone and don't let anyone have access to it. Other than that not to sure.
If I hand over my phone to my friend to have a look at my phone to make a call. I have used ZD box in android. I am looking at similar one for iOS
Delete your messages. Why keep those? Before you hand over your phone, go to your email accounts in settings and turn them off for the mail app. Other stuff you can require log in credentials.If I hand over my phone to my friend to have a look at my phone to make a call.

No the idea is not specific to friends. I am a machinist. Most of the time I will be in the shop working. My phone will be in my office with my instructions to attend the call on my behalf. Get the picture??
There's no app for that because Apple doesn't allow one app to control another. So it would have to be done on the OS level. I'm guessing Apple hasn't seen enough interest in that feature. Perhaps go to their website and make a suggestion. Can't hurt, anyway.
