Once Every memory has its own season, even the ones quietly resting in the depths of your photo library. Open Once, and you’ll meet the version of yourself who once lived on this very day. It isn’t a diary, yet it is more honest than one. It isn’t a time machine, yet it takes you back to a specific moment in your life with ease and warmth. Once shows you the photos and Live Photos taken on the same day in past years, allowing forgotten stories to return and gently illuminate your present. Contact Information · Email: qiu5630@163.com

"We spend our whole lives on the journey to becoming ourselves." 《Becoming · 观己》 is a personal exploration and cognitive evolution tracker designed just for you. It doesn’t track your efficiency or demand productivity. It is simply a quiet companion, guiding you to observe your current emotions, reflect on past insights, and witness your step-by-step journey of "becoming yourself" through the flow of time. In this noisy digital era, 《Becoming》 carves out a warm, minimalist sanctuary for your mind. With a warm paper-texture UI and a ritualistic layout, every note feels like brushstrokes on fine Washi paper—calm, intentional, and grounded. 【Core Features & Design】 - Cognitive Evolution Tracker: Unlike traditional journals that just log daily events, 《Becoming》 focuses on capturing your mental shifts, cognitive breakthroughs, and psychological growth across different life stages. - Third-Party Emotion Observer: Adopt an outside-in perspective. Treat your emotions with gentle detachment—like watching an inner child with unconditional kindness—to foster a stable, lasting inner peace. - Washi Paper Aesthetics: A soothing, low-consumption, warm rice-white textured layout. No stressful KPIs, no reminders to hustle—just long-term, meditative companionship. - Complete Privacy & Freedom: Supported by independent iCloud sync. Your data belongs exclusively to you; your evolution is yours alone to unfold. 【Who is this for?】 - Deep thinkers, independent creators, and practitioners who value their inner world and introspection. - Anyone seeking a quiet, healing space away from high-pressure daily trackers and data anxiety. - People navigating life transitions who want to clearly see their mental evolution and emotional journey. No matter how fast the world changes, in 《Becoming》, you can slow down—to observe, to record, and to become.
