How can I display the date on actual photos taken with iPhone? I need some photos that I have taken to be dated. The date must be displayed on the actual photo (in a similar fashion to how one would think of film photos), but I have no idea how to do this? My understanding is there is an app that does this, but I haven't been able to find it.

Is there an app, or any other way, that would facilitate this?
DateCam S is a free app that will add the date to photos that you take automatically.


  This app simply adds date on your photos.
  
  So now, you can see when the photos were taken!


There are also apps that let you manually add any text (e.g. a date) to your photos. I have used and recommend Camera+ due to its stylistic formatting of the text.
