Time Nest is a cloud-based mobile app designed to help people preserve personal memories, messages, and media through time-based digital capsules. Rather than functioning as traditional cloud storage, the product allows users to lock photos, videos, files, and notes until a chosen future date. I led the product design end to end, shaping the core concept, user flows, and UI, with a focus on clarity, emotional restraint, and long-term usability. The experience supports both private and shared capsules, scheduled unlocks, and gentle reminders when content is ready to be revisited.
