## Focus Timer ## App Blocker In a world full of distractions, FocusFlight offers a unique way to focus: turning every session into an immersive flight journey. From boarding and takeoff to staying focused in the air and landing at the end, FocusFlight combines aviation-inspired design with practical focus tools. It is more than a timer or app blocker — it is an experience that helps you avoid distractions, get into flow, and complete what matters. FocusFlight has been featured by the App Store as App of the Day. Whether you are studying, working, reading, or simply trying to put your phone down, FocusFlight helps you start with intention and end with a sense of completion. FOCUSFLIGHT FEATURES 【Immersive Flight Experience】 Opening FocusFlight feels like boarding a focus flight. Set your boarding pass, choose your task and focus duration, then begin your own deep focus journey. When the session ends, your flight lands safely with a clear sense of achievement. 【Airplane Mode, Block Distractions】 Turn on “Airplane Mode” to block distracting apps and websites during your focus session. Powered by Apple’s Screen Time integration, FocusFlight helps you stay away from interruptions and focus on what matters. 【3D Map Window View】 During your focus session, watch your journey through a 3D map window. As time passes, your flight moves across the world map, turning focus into a journey you can see and feel. 【3D Flight Routes】 Every focus session becomes a visualized flight route. See where you departed, where you are heading, and review the routes you have completed. 【Random Route Mode】 Not sure where to fly? Start with Random Route Mode. No need to choose a destination in advance — just begin focusing, and discover where you land when the session ends. 【FlightLog】 Every focus flight is saved in FlightLog. Review your departure city, landing city, focus duration, flight distance, and route history. 【Membership Cards & Flight Miles】 As your focus time and flight miles grow, you can unlock and upgrade your own membership cards. Each card marks your progress and gives your journey a stronger sense of identity. 【Multiple Map Modes】 FocusFlight offers 3D, satellite, and classic map modes. Explore routes and destinations from different perspectives, and enjoy traveling the world while staying focused. 【White Noise & Focus Music】 During each focus flight, you can turn on white noise or focus music to create a calmer environment for studying, working, or reading. From airplane ambience to soothing focus tracks, FocusFlight helps you enter a quieter, more focused state. 【Focus Records & Data Tracking】 Each session leaves a clear record, including your boarding pass, flight data, route, and focus duration. Use these records to review your focus habits and see the value of every session. 【Different Focus Types】 Choose focus types through seat options, such as study, work, reading, or creative time. Make every flight better matched to your current task, and make focusing more flexible and fun.
