There's no need for most apps to track your location at all times. However, before iOS 8, the only choices you had for location tracking was Always or Never. So if you wanted your photos to be tagged with the location in which they were taken, you had to allow the Camera app to always track your location, which could drain your battery and use your data unnecessarily. Now, iOS 8 allows you to set certain apps to only track your location while the app is in use.
