FocusWindow is an immersive focus tool. Opening the app feels like opening a window to another world. Ocean waves by the shore, views from a moving train, a gentle forest breeze, city lights at night… With immersive scene videos, focusing becomes calm and natural instead of dull and forced. Whether you're studying, writing, coding, reading, or simply reflecting, Focus Window helps you enter a deeper state of concentration with ease. An Immersive Focus Experience Unlike traditional Pomodoro timers, Focus Window creates a focused atmosphere through immersive scenes. It feels like sitting: by a seaside window in a mountain cabin on a moving train during a quiet rainy night Let time flow naturally while you focus. Key Features Focus Timer Clear timing and progress display. Start and end focus sessions anytime. Immersive Window Scenes Window views such as airplane windows, cruise ship cabins, and multiple weather and time-of-day atmospheres. Ambient Sound Mixer Combine sounds like ocean waves, rain, wind, and campfire to create your ideal focus environment. Focus Tags Add tags to each focus session (work, study, reading, meditation, rest, creativity). History & Statistics Review your focus sessions, total time, and long-term trends. 3D Heatmap Turn your focus data into a beautiful 3D heatmap visualization. STL Export Export your 3D heatmap as an STL file to save or even 3D print your focus history. Your Apple ID account will be charged upon confirmation of subscription.
