Stay. Focus. Grow. PupFocus is a simple Pomodoro timer that helps you stay focused, one session at a time. Set a timer, get to work, and let a calm, loyal puppy keep you company while you study, work, or build better habits. Staying focused feels easier when a puppy is rooting for you. How PupFocus Works • Set a focus session based on the Pomodoro technique Choose a classic 25 minutes of focused work with a 5-minute break, or customize the length to match your task, deadline, and energy. • Work distraction-free while your puppy keeps you accountable Your pup stays on screen during your session, giving you a steady visual reminder to stay in the app and on task until the timer ends. • Take short, intentional breaks Step away, stretch, refill your water, or rest your eyes. Because you know a break is scheduled, it is easier to push through tough moments without checking your phone every few minutes. • Repeat simple focus cycles to build consistency Stack sessions to get through revision chapters, deep work blocks, side projects, or your daily to-do list without burning out. Your puppy responds to how you use your focus time. Stick with your sessions, and your pup reflects your steady progress, turning your focus streaks into a gentle, visual reminder of how far you have come. Why PupFocus? • Minimal, clean Pomodoro timer No clutter, no complex settings, no endless options to tweak. Open the app, tap start, and focus. PupFocus quietly handles the timing so you can stay in flow. • Puppy-powered motivation, not pressure Instead of harsh alarms and stressful countdowns, your pup offers calm encouragement. Sessions feel like a small promise to your puppy, making it easier to come back and try again. • Works for any type of focused work Use PupFocus to prepare for exams, review notes, write essays, code features, read books, plan your week, learn a language, or clear your inbox in focused bursts. • Built to help you improve over time Regular sessions train your brain to start faster, resist distractions, and stay with a task a little longer each day. Over time, you get more done in less time, with less mental effort. • Calm, gentle design Soft visuals and a straightforward layout keep your screen quiet. No flashing elements, no noisy animations, just a peaceful space to focus. • Designed for real life Whether you have five minutes between meetings or an entire evening to study, you can start a session that fits your schedule instead of forcing your day around a timer. No pressure. No perfection. Just focused time, broken into pieces you can actually handle. Perfect For • Students who want more effective, less stressful study sessions and easier exam prep • Professionals who need distraction-free deep work blocks without constant notifications • Creatives who want enough structure to start, without losing their sense of flow • Anyone building better focus habits a few minutes at a time • Anyone who simply works better with a quiet, supportive puppy nearby Download PupFocus and turn your focus time into something you actually look forward to, one calm session at a time.
