A minimalist focus timer built for people who value simplicity over gimmicks. No coins to collect. No plants to grow. Just you, a timer, and the work that matters. **Why another timer app?** Most productivity apps try to motivate you with games, rewards, and complicated systems. But if you struggle with procrastination and distraction, the last thing you need is another app competing for your attention. This is the opposite. A clean, distraction-free timer designed to help you start a focus session and actually finish it. **How it works** The Pomodoro Technique is simple: work in focused sprints, take short breaks, repeat. Research shows this method improves concentration, reduces mental fatigue, and helps you get things done without burning out. 1. Choose a task 2. Start a focus session (25 minutes by default) 3. Work until the timer ends 4. Take a short break (5 minutes) 5. After 4 sessions, take a long break That's it. No complexity. No learning curve. Open the app and start. **Built for deep work** Deep work requires eliminating distractions. The interface stays minimal so your mind stays on your task. No social features. No notifications begging you to come back. No ads interrupting your flow state. Just a timer that does exactly what a timer should do. **For students and professionals** Whether you need a study timer for exam preparation, a work timer for remote work, or simply a way to beat procrastination and stay focused, this app adapts to your workflow. Use it for: - Studying and homework - Writing and creative work - Coding and development - Reading and research - Any task requiring sustained concentration **Features** Simple session tracking See your completed focus sessions at a glance. Statistics show your progress over days and weeks so you can understand your productivity patterns. Customizable intervals Adjust focus time, short breaks, and long breaks to match how you work best. Some people thrive with 25-minute sessions. Others prefer 50-minute deep work blocks. You decide. Minimal interface A clean timer. Clear typography. No clutter. Designed to be opened, used, and closed so you can focus on what actually matters. Break reminders Notifications tell you when your session ends and when your break is over. Step away from the screen. Rest your eyes. Come back refreshed. No account required Your data stays on your device. No sign-ups, no passwords, no cloud sync unless you want it. **What this app will not do** This app will not gamify your productivity. It will not reward you with virtual currency or unlock achievements. It will not add features just because other apps have them. Minimalist means saying no to everything that does not directly help you focus. **The philosophy** Productivity is not about apps. It is about doing the work. The best tool is the one that gets out of your way and lets you start. If you have tried complicated systems and found yourself spending more time managing the system than doing actual work, this app is for you. If you want a simple timer that respects your time and attention, this app is for you. **Start your first session today** Download the app. Set a timer. Begin. No tutorials. No complicated onboarding. No friction between you and focused work. Your time is limited. Spend it on what matters.
