Living Frame In development

A living family photo frame on the iPhone home screen

A parent shares one chosen photo of their child each day. Grandparents see it on their home screen widget and send a heart with one tap. Photos sync through the family's own iCloud, with no servers of ours. Over a year, the album becomes the child's first-year book, ready to print.

About

Nep is the product brand of LB Studio Nepcuaban, founded in September 2026 by Le Thai Binh, an independent developer in Vietnam. We are a small team that uses AI agents (Claude Code) for planning, coding, testing and review, so we can ship quality apps fast with a lean budget.
