Sat for hours but feel like nothing got done? Count the time you truly focused, not the time you sat there. Haruda Focus is a Pomodoro study timer that tracks every session and locks distracting apps. Made for students in exam season, anyone studying for a certification, and anyone tracking real study time every day. ■ Time your study A Pomodoro timer that repeats "25 min focus, 5 min break" in sets. Add a long break after each set, save your own Pomo Presets, and let Auto flow start each break and Pomodoro for you. Skip setup with the stopwatch, or use a saved timer for fixed blocks like a practice test. ■ Focus Lock While you focus, only apps you allow will open. The lock lifts during breaks. ■ Records & stats Give each session a focus score, then spot patterns in a 24-hour timeline, daily/weekly/monthly stats, and time by subject. ■ D-Day countdown See the days left until your exam whenever you open the app. ■ Together Sign in, set up a private space with a few friends, and see each other focus. Leave quiet cheers. No leaderboards, just the feeling of studying side by side. ■ Also Sound, vibration, and flash alerts, plus 13 languages. Switch devices and your records follow you when you sign in. ■ Premium (one-time purchase) No ads and unlimited Pomo Presets (up to 3 without Premium). When tasks pile up, just do it. Think "I can" instead of "how do I do this?"

Verdict
The clearest difference is ads: ChatAI at none against Haruda Focus's shown. Haruda Focus's advantage is update cadence (every 4 days vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
