Pictosaur ($1.99) by TwoSeventy Co. is a photography app that lets you capture changes in time with a little extra help. Capture the growth of your baby, or the gradual increase in water along the river’s edge as winter goes by. Let this app be your guide in recreating the exact shot over and over again.

This app uses a special, proprietary alignment program that lets you see a ghost image of what was previously photographed with the app. Take your first picture, then use the app to line up the second picture by placing the object (or pet, or baby) in as close to the same position as before.

The ghost image will appear to help you align the shot, but there is also an internal feature that uses your device’s gyroscope to help determine the exact angle that you were holding it for the previous picture.

You can set the app to remind you of when to take another picture. For example, you can set a reminder to take a picture of the turkey that is cooking in the oven every 30 minutes so you can view the process of it turning golden brown.

You can also set the app to remind you to take another picture every day, week, month, or year. If you want to track your weight loss, you can use this app to capture the changes on a weekly basis.

You can add your series to a special collage so that you can fit them into one attractive frame, or you can view them individually. You can also share your series of photos with friends and family through email or Twitter.

The alignment assist feature works very well. However, the rest of the user interface is a little awkward. For example, there doesn’t appear to be any way to edit your series. You can’t change how often you want to be reminded to take a photo. You can’t rename your series, and you can’t delete a series of photos all at once.

[UPDATE] The developer contacted us to explain how to edit the series. There is an info button at the top-right corner that will allow you to access edits to the entire series. You can change the reminder, rename the group, and delete the whole series by tapping the little “i” when you are at the screen that shows all photos.

Other than the clunky interface, this app works pretty well. It is ideal for capturing changes over time. This will prove to be useful for taking pictures of babies, new puppies, blooming flowers, and all manner of things that change with time. The app is a bit pricey for what it is at $1.99, but maybe you could try getting it to go free by “Bumping” it in our AppsGoneFree app.
