Natour

Natour is a Photo Journaling app focused on capturing the changes on nature, the app main feature focus on taking a photo of something or someplace where nature captures your attention. The app then let you create an alert to remind you to take another photo of the same thing when you want and then puts an overlay of the last photo in front of the camera screen, you can do this how many times you want, After some time you're able to convert your collections into gifs or vídeos and see how nature present in places changes overtime.
