Here is a great little application called Project 365. It allows you to take a picture every day of the year, as you normally do with your iPhone, and store it like a photo album for the year. The no-add version Project 365 Pro also lets you view it as a slideshow, and it costs just 99 cents.
Whether you want to record your child's first year, the year leading up to a wedding, the view from the same place every day or compare the yearly weather, Project 365 is for you. It allows you to crop images, add captions and view the day and year of the picture.
It's a great way to document one year of your life and get better at taking pictures at the same time. So get this app, get out your iPhone and take a new picture every day.
