Take a little half day for yourself. Life doesn’t always have to be a sprint. Little Halfday is a cozy focus and productivity app designed to help you step away from distractions, settle into the moment, and make focused time feel more peaceful. Put down the endless scrolling. Sit by the lake, listen to the water, and let a little fishing cat keep you company while you work, study, read, exercise, or simply slow down. Here, focus isn’t a battle. It’s a small, quiet ritual you can come back to every day. YOUR LITTLE FOCUS COMPANION Start a focus session and your tiny fishing cat settles in beside you. No pressure, no complicated setup—just a calm companion while you spend time on what matters. Whether you’re studying, working on a project, reading, or fighting procrastination, Little Halfday gives you a distraction-free space to get started. FOCUS. FISH. COLLECT. Every focus session brings a little adventure. Spend focused time by the water to catch fish and discover marine creatures such as starfish, jellyfish, and hermit crabs. Keep focusing to unlock new fishing spots, expand your collection, and discover fun facts along the way. Your focus time becomes more than a number—it becomes a little world you build, one session at a time. THE FOCUS EXPERIENCE Flexible Focus Modes • Pomodoro timer for structured focus sessions • Stopwatch count-up mode for flexible, open-ended work Distraction Blocker Block distracting apps such as Instagram, TikTok, Discord, and more while you focus. Pause & Resume Pause when life interrupts, then come back without losing your rhythm. Music & Ambient Sounds Create a calm focus atmosphere with built-in music and relaxing ambient sounds. Rewarding Progress Complete a session—or finish early—and continue making progress toward your collection. TURN FOCUS INTO A ROUTINE Real change rarely comes from one huge burst of productivity. It comes from small habits repeated day after day. Create Focus Plans and routines for: • Deep Work • Study & Reading • Workout • Meditation • Yoga • Bedtime Wind-down • Any activity you want to make a habit Create different schedules for weekdays and weekends. With Scheduled Start, set your routine once and automatically start your focus session at the same time each day. Less planning. Less phone checking. More time for what matters. QUICK START Sometimes you don’t need another productivity system. You just need to start. Use Quick Start cards for Work, Read & Study, Workout, Yoga, and Bedtime. One tap and you’re ready to focus. UNDERSTAND WHERE YOUR TIME GOES Little Halfday uses Apple’s Screen Time API to help you understand and manage device usage. Track: • Daily focus duration • Completed sessions • Focus check-in history • Phone usage trends • Distracting app usage patterns • Progress in time management and habits A DIFFERENT KIND OF PRODUCTIVITY APP Little Halfday isn’t about squeezing every task into your day. It’s about making room for focused time. A little time to work. A little time to study. A little time to read. A little time to move. A little time to simply be. When the world gets noisy, there’s always a quiet lake, a fishing cat, and one more little catch waiting for you. SIDE EFFECTS MAY INCLUDE More focused minutes. Less mindless scrolling. Better daily routines. A surprising amount of knowledge about fish. And the occasional thought: “Just one more catch.” WHY LITTLE HALFDAY? Because you don’t always need a full reset. Sometimes, you just need a little half day—a small pocket of time that belongs entirely to you. Little Halfday — your little moment of calm.
