iPhone photo app similar to Instagram

This app is a photo editing app but with only one filter/edit. It simply allows users to take photo or choose existing photo. Then, there is a page where the filter is shown as on/off with a simple button. Lastly, the photo can be shared to Instagram, Facebook, Twitter, Save to camera roll, Message (SMS), or Email. The login scheme is Facebook or normal create account with email and password required. The PSD design is complete and flow map is available too. The photo filter would be a requirement. You can use a pre built photo app such as Aviary or Gimp command line or another program that would get the job done, but I need this one custom filter for it. The filter can easily be made in photoshop, but I'm not sure if you can transfer it out of photoshop. I would prefer to build this on Parse. Pages: - Landing/login page (Login with Facebook or create account with just email address and password) - Camera to take a photo (This page has an option to select photos from stored on the phone) - Select Photos page (This is when someone wants to edit an existing photo on their phone) - Edit page (This page shows the chosen image and a simple on/off button which shows the image with the filter on and off) - Share page (Sharing through Instagram, Facebook, Twitter, Save to camera roll, send text message, or email photo) - Account page (show all photos user has edited / email address and button to change/reset password)
