Falling squarely into the “Why didn’t I think of that?!” category, Since is a gorgeous and unique photo editor for the iPhone that is now available for free for a limited time. This isn’t just another typical photo editor that tosses in a bunch of overused filters and sends the user on his or her way. Instead, Since is a novel app that serves a single awesome function.

Basically, since gives the user various unique ways to combine multiple photos of the same subject into one image. The result is a single photo that shows a scene changing over time.

From the app’s description:

Since makes time flow into one photo or video.
Series of photos can be combined in various styles.

#1. Photo
– Set as guide image.
– Toggle active/inactive state. (Inactive photos will not be used in a result photo/video)
– Save to camera roll
– Delete a photo
– Swipe left/right to change order of a photo.

#2. Camera
– Five types of guide image mode will help you take exact photos you expect.
– Guide lines can be customizable by dragging
– Timer Shutter
– Camera options are saved for each ‘Since’ so you don’t need to set every time.

#3. Combined Photo
– Size and location of each photo can be edited. (Editing is restricted when the number of photos are over editing limit)
– Swipe up/down or left/right will reverse combine order.
– Drag up or down to adjust video play speed.

#4. Save and Share
– Combined photo can be shared via email, message, SNS or edited with other applications supports on your device.
