I want to password lock some 'specific apps on my phone . In particular wechat and what'sapp . So that if I lend my phone to someone else they can make calls use other apps etc but cannot open and view my we chat . I did a search and came up with visiDon apps lock plus but from the reviews it seems like the best of a bad bunch .
I know a lot of techs on this site so any recommendation appreciated for a suitable app or other solution .
Thanks
