Wikipedia says "Time-lapse photography is a cinematography technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that which will be used to play the sequence back. When replayed at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, and then played back at 30 frames per second; the result would be an apparent increase of speed by 30 times. Time-lapse photography can be considered to be the opposite of high speed photography."
Time Lapse Photography has been around for a long time, it is not something new but has been around before Internet was even available. According to Wikipedia, "the first use of time-lapse photography in a feature film was in Georges Méliès' motion picture Carrefour De L'Opera (1897)". However, before the advert of camera equiped smartphones and the availability of time-lapse photography smartphone application, it is not practical for ordinary people to take time-lapse photographs. Therefore, the ability to take time-lapse photographs and then process it to create the time-lapse video is mainly limited to those in the profession or with professional camera capable of time-lapse photography.
These videos are examples of what you can create by using Time Lapse Photography. Do you have something in mind you plan to film to show the world?
With the arrival of Android 4.0, time-lapse photography is going to become a build-in feature of all Android devices. For those running Android 3.x or earlier, there had been a number of free and paid apps available too for you to take time-lapse photos/videos.
So, why do you want to use our 24/7 Time Lapse app instead?
One very simple reason.

The claims are true
I've tested for 3 hours, capturing a photo every minute, and the battery level is the same as if the phone has not been used.
