Wave is the best new way to share photos with your friends anonymously and with a sense of ephemerality. Photos posted on Wave can be viewed once by each follower for 24 hours after posting.
Wave was created to be an environment in which people could share beautiful photos without putting their name to them. This way, people will not feel obligated to post "look at me" posts and will instead post cool photos for their friends to look at.
Using Wave is simple. Just open the app, snap a picture, add a filter, and share it. Adding friends is also very simple: just tap the plus icon in the friends tab and type in their username. Then, tap the plus icon again.
If youre under 13, the app will only function as a camera with which you can take photos, add filters to those photos, and save them. Also, if you do not wish to make an account, you can use the non-account features of the app by tapping anywhere in the blue background when you open the app.
