Stay connected to the people who matter most with Retro, a private, friends-only space that invites you to share meaningful moments throughout your week.

What we love: How the app gives you a week-by-week view of the photos on your iPhone—an approach that encourages you to slow down and appreciate the little moments.

Quick tip: Retro can print and mail a physical postcard of one of your photos. Just tap a photo, tap the three dots, add a message, and send. Your recipient will be asked to share their address—Retro will handle the rest.

Meet the creator: Retro founders were looking for an alternative to the typical social feed. “We’re optimizing for people first,” says CEO Nathan Sharp. “In every detail of our product, we want you to see the fingerprints of a team that cares about your delight.”
