WallaMe is a free iOS and Android app that allows users to hide and share messages in the real world using augmented reality.
[3] Users can take a picture of a surface around them and write, draw and add stickers and photos on them.
Once the message (called Wall) is completed, it will be geolocalized and will remain visible through WallaMe's AR viewer by everyone passing by.
[4] All the Walls created worldwide can be seen in a feed similar to those of social networks like Facebook and Instagram, and can be liked, commented on, and shared outside the app.
Venturebeat cited WallaMe Ltd. in a list of 100 noteworthy young startups.
