Spent hours at your desk but feel like nothing got done? Track the time you actually focused, not just the time you sat there. Haruda Focus is a Pomodoro study timer that logs your real study hours and locks distracting apps while you work. Made for high school and college students heading into finals, anyone preparing for a certification or licensing exam, and anyone who wants to log real study hours every day. ■ Pomodoro, stopwatch & timers A Pomodoro timer built on the classic rhythm of 25 minutes of focus and a 5-minute break. Turn on Set Mode for a long break after every few rounds, save your own Pomo Presets, and switch on Auto flow so focus sessions and breaks keep rolling on their own. Don't feel like setting anything up? Start the stopwatch. For fixed blocks like a practice test, start a saved timer. ■ Focus Lock While you focus, only the apps you allow will open. Everything unlocks during breaks. Focus Lock uses Apple's Screen Time. ■ Records & stats Give each session a Focus Score when it ends. Then see your patterns at a glance: a 24-hour timeline, daily, weekly and monthly stats, and time by category, such as each subject you study. ■ D-Day countdown See how many days are left until your exam every time you open the app. ■ Home Screen & Lock Screen widgets See today's focus time and your nearest D-Day without opening the app. Tap the start button on the Home Screen widget to open the app, and your focus session starts 3 seconds later. ■ Together Sign in, create a private space with a few friends, see each other focusing, and send quiet cheers. No leaderboards, just the feeling of studying side by side. ■ Also Sound, vibration and flash alerts when a session ends. Sign in to keep your records in sync across devices. Available in 13 languages. ■ Premium (one-time purchase) No ads, plus unlimited Pomo Presets (free users can save up to 3). When things pile up, just start. Don't worry about how. Once you start, you'll get there.
