Photo sharing app

A photo sharing app for the iphone/android phones. when you open the app it will ask you to fill your phone number, it will then text the person with an access code and it mst be entered, this will be done only once the first time they open the app. it will ask to access their contacts form the phone, it will be similar to whatsapp function. you can create albums, and within an album you can add friends from your contact list to join. once you click on an album you made, you can click the take picture button, it will be a camera to take pictures and videos, it will look just like a normal camera on the iphone with same features, but on top center it will be written the albums name, once they take a picture everyone on the contact list in the album will see the photo instantly. theres a function where it will ask for your locoation and if want to add to the photo, so for example you are in new york times square, you make a new album called new york vacation, you add few friends and family from your contact list, which gives them privilige to see the photos, then you take pictures and you decided to add location, so on the bottom right corner the location will be written, and everyone on the list will recieve the photos as its being taken on the same app. you can also give some friends from your list priviliges to take photos too, so if its someones wedding, the married couple can make an album and have all their invites in the list and allow them to take pictures too so that album will grow with many pictures from everyone, and you can see the photos by two options, chronological time, or by alphabetical names of the people on the list. i can explain in more details and have sketches to show, this is just a little summary to get an idea, thanks.
