Observatory is a calm focus and deep-work app. Start a session on one task, stay with it, and see real patterns in how you focus. Free to start. When you drift or pause, that time isn't counted as focus. When you focus, it counts. And a quiet day is never treated as a failure. FOCUS Start a focus session on a single task and stay with it A glowing orb that keeps you company while you work, with no pressure and no gamification Drift detection: leave the app and a gentle reminder brings you back Pauses and drifts are tracked, and never counted as focus Six focus environments: Rainfall, Tide, Hearth, Nightfall, Drift and Forest Ambient focus sounds to help you settle in See your calendar alongside your day, and turn events into focus tasks PROGRESS Today's focus inside rings for your daily goal, active days and on-task rate Clear charts of your focus time, with more detail on shorter ranges A heatmap of when your sessions tend to start across the week Records and a Grind Score, drawn from your own sessions Your trajectory over time, so you can see how you're changing Focus time per project and per task, including estimate versus actual A COMPANION THAT LEARNS YOU Discovers your patterns: when you focus best, your strongest days, how your sessions run deepest Tells you what it notices in plain words, based on your own sessions Suggests small experiments, and gives an honest read on whether they worked A weekly review that brings your week together and shows what changed A Story of your focus to look back on When there isn't enough data to say something, it says so MAKE IT YOURS Focus themes, Home backdrops, orb colours and sounds Light and dark mode A daily focus goal and a weekly consistency goal Every number and sentence in Observatory comes from your own sessions.
