Good said the sharpness of the camera in the new iPhone 4S meant the app could digitise photos at the same quality as a professional scanning service. Users also have the opportunity to add captions and other information to a photo when it is uploaded.
Good said the public was already using smartphones to archive physical photos, but claimed Shoebox streamlined the whole process.
"Trying to line up four sides of the screen with four edges of the photo can be pretty tough and we realised we could do this for them, and could algorithmically spot [the edges of the photo], and frame it," he said. "We figured if people are doing it already and it isn't perfect and we could build an even better version then that would be super popular."
1000Memories.com went live last year and allows the family and friends of someone who has died to share stories, photos and videos of their loved one online.
In February, 1000Memories attracted angel investors, raising US$3 million ($3.7 million) from Silicon Valley's long-established Greylock Partners and the financial backers of Twitter and Google. Since then, Good said the website had expanded to be a more general "memory-sharing" platform.
"People don't just want to get up the ones of people who have passed away, they want to save all their amazing photos, whether it's of childhood memories or elderly relatives," he said.
Both the Shoebox app and access to the website remain free with no advertising and Good said the project was not making money at this point. There are plans to charge fees for new premium services, but for now he is focused on "building something really awesome that people really like".
"The cool part of being in Silicon Valley is we have amazing investors who believe in what we're doing. They believe in the overall economics ... they believe it can be free and still worthwhile."
