Blot

Fold your phone to print ink

Paint on one half of the inner screen, close your iPhone Duo, and open it again. The wet ink is pressed onto the other half, the way a monotype or a Rorschach card is made. How fast you close it, how long you keep it shut, and how fast you open it all change the print.

Nothing leaves your phone

Blot doesn't collect, send or share any data, and it never connects to the internet. Your prints stay in the app until you save them to Photos or share them yourself.
