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. Such stimulations only provide short-term dopamine hits and do little to improve your actual ability to focus. Improving focus is a marathon, not a sprint. While a single focus session is a short-term goal, the accumulation of those sessions is what builds true, unshakable deep work habits. 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. Stay in the flow by tracking your progress in real-time while the timer is running. • Leave the Logging to Ddidoc The moment your session ends, your hard-earned focus time is saved automatically. We create an environment where you can focus entirely on your next task without the hassle of manual logging. • Visualize Your Growth with Data Reflect on your day with meaningful data, not just passing time. We show you exactly how high-density your day was by analyzing your cumulative focus and rest periods. • In-depth Immersion Pattern Analysis Discover your personal focus trends through weekly and monthly summary reports. Stay on track by checking your achievement rates against your goals for a better tomorrow. □ Ddidoc is Recommended For • Those who feel drained just by getting ready If you’ve ever used up your energy setting up timers and picking categories before actually starting, We built this for you so you don't waste your focus before you even begin. • Those who find logging to be a chore Tired of the hassle of manually entering your hours after a deep work session? Let the app handle the records so you can enjoy your well-deserved break. • Those who want to see their efforts in numbers Sometimes it feels vague whether you're actually making progress. We recommend this to those who want to stay motivated by seeing their growth visualized through charts. • Those who seek calm immersion over dopamine hits Instead of flashy rewards or noisy notifications, Ddidoc will be the most comfortable tool for those who want a quiet, deep space for focus. □ Data & Privacy • Your Data, Safe Anywhere Access your focus records in real-time on your iPad, even if you started them on your iPhone, through iCloud sync. Even if you change devices or reinstall the app, your traces of immersion are safely stored in the cloud and can be retrieved at any time. • Privacy First Ddidoc never sends your focus data to external servers, nor do we share or commercialize it with third parties. We don't know what you're focusing on—we only root for your growth. ※ For more details on data collection and usage, please refer to the ‘App Privacy’ section at the bottom of the App Store page. Ddidoc constantly strives for better features without interrupting your flow of immersion. If you have any feedback or suggestions, please reach out via review or email anytime.
