Input / Output – main screen has a bigger visible button that encourages you take a photo. It is the one input that stands out then all the others.
By taking a photo it is implied that you will send it out and receive responses. Once you take a picture, it gives you a good amount of extra features to add to your photo, making a meme. Text, drawing, stickers, links. It gives you a lot to do and allows you to be as creative as you want.
When you take a picture, the only icon that is in color is the “send” button which makes tells you to go and send that sweet ass photo to all your friends.
It changes color of icons when it wants you click on something and it brings your attention to it. Also, when adding a friend it also recommends you start talking to them by saying, “say hi *insert waving hand emoji.*”
