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.

About

Quartz

Features
Read full description

Quartz is a focus timer that fits the way you actually work — not the other way around. Three modes, one flow. Pomodoro — the classic cycle: focused sessions, short breaks, a long break when you've earned it. Fully adjustable, with named presets and sequences that vary session lengths across a cycle. Free Roam — an open-ended count-up for the days you just want to start and see where the focus takes you. Flowmodoro — work as long as the flow lasts, then take a break you earned: Quartz computes it from how long you focused. Switch between them anywhere — and Quartz always asks before ending a running session, on every device. Everywhere you work. iPhone, iPad, Mac, and Apple Watch — one purchase, everything included. Start and control any mode from your wrist. On the Mac, a menu-bar timer shows your session at a glance, with full controls one click away, and Quartz can open at login. Widgets, Lock Screen widgets, and Live Activities keep your session visible without opening the app. Attach your work. Create tasks and attach one to a session — your focus time is credited to the work it served. History keeps an honest record: finished sessions, skipped ones, and exactly how long each really ran. Understand your focus. Stats show your day at a glance. Quartz Pro adds Insights: completion rate, streaks, adherence, focus by task, your best hours and days, a focus heatmap, and per-device breakdowns — each with clear headline numbers, not just charts. Private by design. No account. No ads. No tracking. Your data lives on your device and in your own private iCloud — invisible to us, synced by Apple. You can even turn iCloud sync off per device. Free forever: the full Pomodoro experience, Free Roam, tasks, history, core stats, widgets, Live Activities, the Apple Watch app, the Mac menu bar, iCloud sync, Focus Filters, and Shortcuts. Quartz Pro (subscription or one-time lifetime, 7-day free trial): Flowmodoro, named presets and badged starters, sequences, custom presets, four premium themes, and the full Insights suite. Nothing you have is ever taken away. Made by one developer who wanted a timer that respects your time — and your data. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
