hamahama: the AI timer that measures your real Lock-in time, so you can compete honestly with friends. The time the stopwatch kept running while you were in the bathroom. The time you scrolled your phone with the timer app open. You tell yourself it was an hour, but you really locked in for half of that. hamahama was built to end that lie. 1. Real Lock-in time, measured by AI - Using your camera, AI checks that you're actually locked in at your desk and counts only the time that's real. - Doze off, pick up your phone, or leave your seat, and the timer stops. - No need to hit pause yourself. The AI handles it. 2. A Lock-in planner that fills itself - Your Lock-in sessions are logged automatically in a 10-minute-block planner. Your day gets organized without writing a thing. - Tap a record to change the subject, or manually add sessions the AI couldn't measure. 3. Lock-in stats - See your Lock-in time and focus rate by day, week, and month, and compare with yesterday, last week, and last month. - Focus rate: shows what % of the time you sat down was real Lock-in time, and where your focus rate ranks among all users. - An hourly graph shows when you stay focused the longest. - Tap a date on the monthly calendar to jump straight to that day's record. - Lock-in streak: grows with every consecutive day you lock in for 10+ minutes. - See how much time you've put into each subject. 4. Weekly timetable - Set a recurring Lock-in schedule for each day of the week, with subjects. 5. Daily goal - Set today's Lock-in goal and see your progress right on the home screen. - If you forget to lock in, a reminder will nudge you first. 6. Lock-in timelapse - When you finish, today's Lock-in session is automatically turned into a timelapse video. - Your Lock-in timer is burned into the video, so you can watch your hours add up. - Videos are kept in the in-app vault for 3 days, and you can save them to Photos or share straight to Instagram. - Videos are created only on your phone. They are never stored on our servers. 7. Compete with friends on real Lock-in time - Create a private group with friends using an invite code, or find and join public groups of people preparing for the same exam through search and categories. - Group rankings are based only on AI-measured Lock-in time. Manually added time doesn't count. - Compare daily, weekly, and monthly rankings, your Lock-in time over the last 7 days, and the group average, all on one screen. - See who has put in how much today, and who's locking in right now. - Get notified when a friend in your group starts locking in. 8. Lock in together on cam - Pick a group from home and jump right in, or create a temporary room and invite friends. - Check yourself with a camera preview before you join. - Feel like you're sitting side by side in a quiet library, while AI measures each person's real Lock-in time. - Toggle your mic on/off and switch cameras smoothly. 9. Lock in solo, too - One tap to start from home, and AI measures your real Lock-in time automatically, even in solo mode. - Perfect for keeping promises to yourself at a cafΓ© or at home. --- Recommended for - Anyone tired of stopwatch timers that let you fool yourself - Anyone who wants to answer "How focused was I today?" with real numbers - Anyone who wants a planner but finds writing everything down a hassle - Anyone who wants to keep a video record of a hard-working day - Students who want to compare real Lock-in time with friends - Exam takers who want to keep pace with others preparing for the same test through groups and cam sessions - Anyone who keeps reaching for their phone at a cafΓ© or at home --- - Get started in 5 seconds with your Apple, Google, or Kakao account - All features are free - For questions, go to [Settings > Contact Us] in the app - Website: https://studyhama.com Only real Lock-in time.
