Most productivity apps are built for today's to-do list. Chekhov is built for the long game — the book you're writing, the degree you're finishing, the business you're building. It connects your daily effort to your biggest ambitions, so you can see your progress adding up and keep going. PLAN BIG, WORK SMALL • Organise your ambitions into projects, broken into phases and tasks • Add subtasks and tags to keep even sprawling projects manageable • A "Today" view surfaces just what needs your attention right now BUILD HABITS THAT STICK • Track habits on the cadence that fits — daily, weekly, monthly, and more • Three ways to complete: a simple check-off, a quantity (pages written, kilometres run), or time spent • Streaks, totals, and a 90-day history grid show your consistency at a glance LOG THE WORK, SEE THE PROGRESS • Time-track work sessions and link them to your projects • Record custom units of progress — words drafted, problems solved, whatever you're measuring • Keep journal-style notes attached to each project, so context never gets lost STAY FOCUSED • A built-in Pomodoro timer structures your work into focused sessions • Start a session from anywhere and get notified when it's time to break KNOW WHERE YOU STAND • Get assessments for your tasks, projects, and habits — and advice on what deserves attention next • Productivity scores and stats turn scattered effort into a clear picture MADE FOR IPHONE AND IPAD • A layout that adapts from phone to iPad, including split view and multitasking • Your data syncs across devices, so you can plan at your desk and check off on the go Five-year plans fail one ordinary day at a time.
