Crossings: Shared Moments

Crossings finds the moments you and a friend were in the same place, even from before you met. The match could be a coffee shop, a concert crowd, a city you both passed through years ago. We surface those quiet overlaps and let you optionally reveal the photos from them to each other.

How it works:

• The app scans your camera roll on-device and uploads only hashed metadata (timestamp + rounded location). No photos, names, or precise coordinates ever leave your phone.
• Add a friend with a 6-character invite code or shareable link.
• We compute "crossings", moments you were both in the same place at the same time, and show them on a timeline.
• For each crossing, you choose whether to reveal photos. Their side stays private until you do.
