Focus is a finite resource. Why waste it before you even start? Start your timer in 1 second. Just open, tap, and immerse. We’ll handle the logging—it's time to settle in with Ddidoc. Don't let your energy drift away from where it's needed most. Ddidoc doesn't distract you with flashy achievements or addictive UI patterns designed just to grab your attention.

Ddidoc is here to be your silent partner in this long-term journey. Today's single second gathers to change your tomorrow. Take that light first step with Ddidoc today. □ Key Features • Customizable Focus & Rest Cycles Set your focus and break intervals based on your daily condition and start immediately.

Deep Focus - Deep Work Timer is a focus timer app built for deep work and flow. Use it as a study timer, work timer, or coding timer to quickly record how long you stayed focused. Your sessions are saved by project, so you can track progress over time and review your productivity with clear stats and a heatmap. Start the focus timer once, and your focus time tracking and time management habits begin to build naturally. The reason to use a focus timer is simple. When you can see how much flow time you achieved today, which projects took most of your time, and whether you are staying consistent (streak), it becomes much easier to plan your next session. [Key Features] 1. Deep Work Focus Timer (Focus Timer) • Simple controls: start, pause, resume, finish • Optional session notes after finishing: record what you worked on • Keep screen on option to prevent the display from turning off during focus • Session recovery when returning from background or restarting the app (within 12 hours) 2. Project-Based Time Tracking (Time Tracker, Work Time Tracking) • Add, edit, and delete projects • Track total deep work time per project and manage status (active/completed) • See at a glance where your focus time goes 3. Statistics and Visualization (Productivity Tracker) • Overall summary: total focus time, number of sessions, average focus time, longest streak • Period stats: today, weekly, monthly, yearly • Recent activity list to quickly review today’s deep work sessions 4. Goals and Streak (Build a Deep Work Habit) • Set a daily goal (30 minutes to 8 hours) • Real-time progress toward your goal • Stay consistent with a streak system that makes progress visible 5. Heatmap (Focus Calendar) • GitHub-style heatmap to view your last 12 weeks of flow and deep work • Color intensity increases as your focus time grows, making improvement easy to see
