Overview
A friendly storage companion, Nova, that shows your phone storage at a glance, suggests what to clean, organises files and protects private ones in a vault.
Challenge & approach
The challenge
Phones fill up with similar shots, screenshots and long videos, and many cleaner apps feel aggressive or opaque about what they remove.
Our approach
The idea is a calm storage companion: show where space goes, suggest easy wins, and never delete anything the user has not reviewed.
