``` Stop staring at your to-do list trying to decide what to do next. Sukima is the app that picks one thing for you, in the moment you're in. When you have a 15-minute gap between meetings, an hour at home before bed, or a quiet morning before the day starts, Sukima tells you what to do with it. Based on your time, your energy, and where you are. HOW IT WORKS Get everything out of your head, by voice or by text. Sukima's AI sorts it once into tasks, projects, goals, and ideas, with priorities, deadlines, and next steps. Then, forever after, it picks what fits the moment you're in. WHAT MAKES SUKIMA DIFFERENT Every other productivity app asks you to organize first. Pick categories. Choose a methodology. Tag everything. Sukima inverts that. You tell it everything once, the AI sorts for you, then when your brain is loud and you can't decide what's next, Sukima decides for you. No system to learn. No methodology to master. No setup ritual. THE NAME Sukima (隙間) is the Japanese word for the small breathing-room gap between things. The pause. The interval. The whole app is built around one insight: you have more usable time than you think, scattered through your day in small windows. The right tool helps you find those gaps and fill them, without making you build a system first. FEATURES - Voice and text capture (AI sorts what you say or type) - "Pick" tab picks one thing based on your time, energy, and location - AI daily planning each morning - Auto-generated next steps for every item - Deadline-aware Today view - Home Screen widget and Control Center tile - iCloud sync across iPhone, iPad, web PRICING Free to start. $9.99/month or $79.99/year for unlimited AI sorting, unlimited Picks, and AI daily planning. Sukima. The app that picks for you, when you can't. SUBSCRIPTION Sukima Pro is an auto-renewable subscription. Monthly and annual plans are available, with the price and length shown on the product page before purchase. Payment is charged to your Apple Account at confirmation, and the subscription renews automatically unless auto-renew is turned off at least 24 hours before the current period ends.
