Free Pomodoro Study Timer & Schedule Planner
Overview
A high-performance, single-file browser application designed to help students and professionals manage their workflow using either the traditional 25/5 Pomodoro method or the 50/10 deep-work technique. This tool provides a clean, distraction-free environment to boost concentration.
Technical Constraints & Directives
- Single File Architecture: All HTML, CSS, and JavaScript must be contained in a single index.html file.
- No Persistent Storage: DO NOT use
localStorage,sessionStorage, or cookies. Maintain state exclusively in memory. - Sandboxed Environment: The app must function within a restricted iframe. Avoid all
alert(),prompt(), andconfirm()calls; use custom HTML modals instead. - No Branding: Ensure the interface is purely descriptive and functional. No fictional brand names or logos.
- Frameworks: Vanilla JavaScript, HTML5, and CSS3 only. Tailwind CSS may be utilized via CDN for styling.
Design Aesthetics
- Color Palette: A professional, airy "Light Mode" aesthetic. Use slate grays (
#334155), soft blues (#0ea5e9), crisp whites (#ffffff), and subtle emerald accents (#10b981) for success states. - Transitions: Implement 300ms cubic-bezier transitions for timer updates and layout shifts. Use soft CSS box-shadows for card elements to create depth without clutter.
- Typography: Utilize system-stack fonts or a clean sans-serif (e.g., Inter or Geist) for readability.
Feature Set
- Interval Toggles: One-click switching between "Short Sprint" (25/5) and "Deep Work" (50/10).
- Customizable Timer: Include an input area for manual minute/second adjustment if the user prefers custom intervals.
- Progress Visualization: A dynamic circular progress ring (SVG-based) that updates in real-time as the timer counts down.
- Session Counter: A counter that tracks completed cycles during the current session.
- Audio Notifications: Integrated browser-based audio cue (using an OscillatorNode or a base64 encoded lightweight sound) to signal when a session ends.
- Custom Modals: Implementation of CSS-only modals for setting adjustments or user confirmation alerts.
UI Layout
- Header: Minimalistic title area (centered).
- Timer Section: Large, bold countdown display positioned centrally. Start/Pause/Reset controls directly underneath.
- Mode Selector: A segmented control toggle to switch between 25/5 and 50/10 presets.
- Schedule Tracker: A simple list area (in-memory) that allows users to add tasks or checkboxes for the day's goals.
- No Footer: The design must terminate cleanly after the content area, with no footer section.
Mobile Responsiveness
- The layout must flex from a desktop-centered card to a full-width vertical stack on mobile devices.
- Touch targets (buttons) must be a minimum of 48x48 pixels to ensure usability on mobile touch screens.

Frequently Asked Questions
Everything you need to know about using this application.
What is the difference between the 50/10 and 25/5 Pomodoro techniques?
The 25/5 technique, known as the standard Pomodoro method, consists of 25 minutes of intense focus followed by a 5-minute break. This structure is ideal for tasks requiring quick bursts of energy or when you are struggling with procrastination, as the short duration feels less daunting and helps maintain steady momentum throughout the day. Conversely, the 50/10 technique is better suited for 'deep work' or complex tasks like coding, essay writing, or studying dense material. By extending the focus block to 50 minutes, you allow yourself more time to reach a flow state, while the longer 10-minute break provides a more substantial recovery period to reset your cognitive resources.
Does this tool save my progress or study schedule?
This application operates entirely in-memory within your web browser for privacy and security. Because it is designed to run in sandboxed environments where storage APIs are restricted, it does not use cookies, localStorage, or IndexedDB to save your data. This means that if you refresh the browser page or close the tab, your current session data will be reset. We recommend keeping your study notes in a separate document and using this tool specifically as a transient, high-performance timer for your active work sessions.
Can I use this timer for tasks other than studying?
Absolutely. While the interface is optimized for academic workflows, the flexible timer settings make it an excellent utility for any time-boxed activity. Whether you are managing administrative tasks, household chores, or creative projects, the interval toggles allow you to adapt your focus duration to fit the specific demands of your current activity. Using a structured timer is a proven strategy for increasing efficiency and preventing burnout, regardless of the task at hand. By forcing a dedicated break period, you maintain a higher quality of output over longer durations compared to working continuously without a timer.
How do I ensure this tool works without interruptions?
To get the best experience, we recommend using this tool in a dedicated browser tab. Since the application relies on browser-side timing, ensure your device's power-saving mode is not set to restrict background tab processes if you intend to minimize the window. Furthermore, because this tool is built as a single-file application with no external dependencies other than standard libraries, it is lightweight and fast-loading. It will function reliably on both desktop and mobile browsers, provided your device has an active internet connection to load the initial interface.
