Frame gives you evidence. Side-by-side comparisons, a scrollable timeline, a dated record you can see and trust. AI ANALYSIS It reads your photos and produces a structured health report covering muscle development, body composition trends, posture, and form. PRIVATE BY DEFAULT Your photos belong to you. Frame does not sell your data. Nothing is shared without your explicit permission. SHARE ON YOUR TERMS Send your progress to a trainer, a family member, or a friend. Or keep it entirely private.

Kumo RAIN is a quiet instrument for thinking, sleeping, and being still. Most sound apps are loud β endless lists, blaring autoplay, one more thing demanding your attention. Kumo RAIN is the opposite. Open it, choose a sound, put the phone down. Itβs built to be listened to, not looked at. Launching with two sound worlds: ι¨ RAIN β let it fall. Steady, soft, or heavy. ζ°΄ WATER β follow the stream. More weather is on the way. β BUILD YOUR OWN QUIET β Layer sounds together and set each level by hand. Choose a texture for every layer. Save the feeling of a place you remember. No two evenings sound alike. β DRIFT OFF β A sleep timer fades gently to silence in 15 to 90 minutes. Fall asleep; the sound bows out on its own. Background and lock-screen playback keep it going while you rest. β A CURATED INDEX, NOT A NOISE DUMP β Every sound is chosen, named, and placed β Water, Earth, Air, Place. Quality over quantity, always. β ON EVERY DEVICE β Create a free account and your library, mixes, and sessions follow you everywhere. β DESIGNED TO DISAPPEAR β A calm, Japanese ink-wash aesthetic. Warm paper, deep ink, a single brush-stroke circle. Nothing blinks, nothing nags. Made for people who want calm to think, sleep, or simply be still β designers and readers, parents, and anyone awake at 2am. PRO β COMING SOON A future subscription will unlock every sound and weekly new drops, unlimited saved mixes, lossless offline listening, home-screen widgets, and a sleep journal. Today, Kumo RAIN is free. Turn it on. Let the room fill. Disappear for a while. β Sounds used under licence. Kumo RAIN (ι² kumo, βcloudβ Β· ι¨ βrainβ).
