iz — leave something behind in the city
A location-based social app for leaving photos, thoughts, music, books, and feelings for people who visit the same place.
Field notes
The site describes a proximity-gated posting system: nearby traces appear on a radar, then open only when a visitor reaches the relevant location. Posts can contain a sentence, photo, song, book, or postcard-like message, while a response becomes a conversation only when feelings are mutual. One example shows 10 traces about 21 metres away, and the product says traces may fade after 30 days. Approximate location, blocking, reporting, and account-deletion controls are presented as part of the experience.
