You're alone. But not lonely. Tomoshibi is a quiet, candle-lit study room for the late-night hours — a calm place to focus, alone, together. By night you light a candle; by day, a stick of incense. For as long as your light stays lit, that's tonight's work, quietly recorded. No badges, no nagging notifications. Just one small light, glowing beside you. And somewhere out there, someone else is lighting theirs too. A stranger you'll never meet, sharing the same night. That quiet presence makes the hours feel a little less lonely. FOR NIGHTS LIKE THESE - Working on a side project after your day job - Studying for a certification, quietly and steadily - Giving yourself a little time on a tiring night - Wanting to focus alone — without feeling completely alone WHAT YOU CAN DO - Light — a candle or incense to quietly track your focused time - Everyone's Night — sense the lights of others glowing somewhere tonight - Ambient sound — rain, the quiet of night, a distant campfire; choose tonight's backdrop - Tonight's intention — write one line, then gently reflect at the end - Nice work — send and receive a soft "nice work" with a stranger - Your record — the nights you light quietly add up on your calendar WHAT TOMOSHIBI LEAVES OUT — ON PURPOSE - No leaderboards or rankings - No guilt-tripping streaks that punish you for missing a day - No trees, points, or games that turn focus into competition - No video calls or real-name social Tomoshibi isn't about competing. It's about quiet company. We'll never compare your pace to anyone else's.
