Our App today is called Retro. There is no shortage of social media out there. This one is unique, because it's purely a photo journal app. And it helps you look back on the times that you have experienced a week at a time. The app also lets you turn your photos into actual postcards that you can send to your friends and family through the Post Office. You can make picture collages and slideshows from anything that you've shared on Retro. There's also a section where you can set up private photo sharing with other people in your circle. You can put the pictures you shot at a particular event, and have others share their photos from the same event. It has chat functions for private conversations or group chats. This photo app is a lot simpler and more personal than what you'd get through Instagram. Retro - Social Photo Journal is a free app on iTunes.
