Some diaries are written just for yourself. Some moments are meant to be recorded as they truly are. No need for perfection, no need to revise. Writing who you are at that moment is an honest act of existence. Lightmark is a diary app that does not allow editing after writing. It blends a sense of time with emotional expression, gently guiding you to meet yourself. 【 Philosophy · Faithful to the Present 】 Lightmark’s writing approach is inspired by the psychological concepts of “non-judgmental writing” and “immediate recording.” Once submitted, your words cannot be changed—not to limit you, but as a gentle exercise: * Accept your emotions instead of adjusting them; * Capture your thoughts as they were, not rewritten by later understanding; * Let go of “right or wrong” and “perfection,” leaving only your true self. Every Lightmark entry is an echo through time and space. 【 Recording Methods · Multi-Sensory 】 Your feelings aren’t only expressed in words. Lightmark supports multiple sensory recording options, letting you capture emotions naturally: * Text Diary: Quietly write and record inner moments; * Voice Diary: No need to organize language, just speak; * Photo Capture: One image records the world you see; * Video Clips: The authentic sound of life, the most vivid memories; * Tag System: Seamlessly insert tags anywhere in text, freely create multi-level structures (e.g., #emotion/happy, #life/family) to lightly organize your diary. Whether it’s a midnight monologue, a morning ray of light, or a fleeting tear, you can collect it your way. 【 Annual Lightmap · See Your Journey 】 Lightmark’s unique “Lightmap” forms your year in a dot matrix. Each day you write sends ripples across the map. * The more you write, the brighter that day’s light point shines; * You can add marks for special days (Unlock this feature by purchasing the full version.). The Lightmap doesn’t tell you which days you “missed” writing and won’t push you to check in. Instead, it gently shows which days were quiet or full of emotion. It’s the path you’ve walked with yourself—a commemorative map left by time. 【 Timeline Diary · Your Life Chronicle 】 Lightmark uses a “one page per day” design, automatically gathering all texts, photos, voice recordings, and videos of the day into time slices—your daily archive. You’ll find life needs no polish; just capture the moment, and time will weave your story. 【 Design Philosophy · Simple · Gentle 】 Lightmark avoids complex categories, using tags for light management, keeping only the essence of “recording.” You’re not writing tasks, but your heart’s voice. * Minimal interface for immersive writing * No distractions, no ads, no popups * Supports dark mode, fitting the quiet of night 【 Who is it for? 】 * People who want to keep diaries but can’t stick with it * People who want to record emotions but don’t know where to start * Those who love the purity of paper diaries but want better saving and searching * Anyone wanting to practice self-acceptance without being trapped by “perfection” Terms of Use: https://app.qlulu.fun/termsofuse Privacy Poclicy: https://app.qlulu.fun/privacy
