The timer's been working hard. But what did I actually do? There's more to studying than a number on a timer. 따 is a study timer that lets you melt ice with friends and capture your study sessions in timelapse. Study appointments, reminders, and motivation features give you a reason to get started when sitting down feels like the hardest part. • Keep a record of the work behind the hours Start the timer and use your camera to capture yourself studying. The problems you worked through. The pages you turned. Another day you showed up at your desk. You don't need to wait for your results to feel proud of the effort. • Study together until the ice melts Your study time melts the ice. Invite friends, and everyone's time contributes to the same block. Join a friend who's studying now, or study at different times and work toward the same finish. • Finish the ice. Share the story. When the ice has fully melted, a recap video brings your shared progress together. If you've captured camera footage, you can also watch a personal video featuring your own study moments. Save the finished videos and share them with friends. Go beyond “How many hours?” and show “Here's what I worked on.” • Make an appointment to start studying Sometimes “just a little longer” turns into another hour. Choose a time to start studying and get a reminder. If you request phone support in advance and miss your study appointment, you may receive a call from someone on the 따 team. Your study appointments are private. They aren't shared with friends. • Start solo. Bring friends along. No study buddy yet? Start melting your own ice. Look back at your study record, then come back for your next session. Invite friends whenever you're ready. Keep more than the hours. Keep the moments you put in. Open 따 and start melting your first ice.
