There is one application for mobile phones phones iPhone, with the name Everyday and makes the following simple: it reminds you to take a selfie every day at the same time and then merges all the images into one video, so you'll be able to see how you change over time, whether in appearance or mood.
All you need to do is take your first selfie. You will be asked to pose at a certain distance so that the main elements of your face (your eyes, nose and mouth) fall up and down in the same place for the subsequent video to be coherent. After the first one photo all you have to do is set a reminder for the time of day to take your next selfie.
You also have the ability to set notifications not to be at the same time. If you like it hard or if you want to confuse it a bit, you can receive reminders when you are at a specific location of your choice or randomly at some other point during the day.
You just have a decent set of selfies, the application will combine them in a timelapse with your face.
The app was available for devices iPhone but in the past it was re-released today with a revised interface and a host of new features that improve its usability.
