OCUS. RECORD. LOOK BACK. LapseIn turns your focus sessions into time-lapse videos. Start a timer, point your camera at your workspace, and get to work. When the session ends, edit your time-lapse with customizable overlays for your focus time, goals, streaks, and progress. Save the video in LapseIn, export it, share it, or keep only a session log when you don’t want to store a video. CHALLENGE A FRIEND Send a friend a focus challenge and work toward a time goal together. Challenges share your session time and progress without sharing your video.

STAY ACCOUNTABLE Add friends as accountability partners, share 24-hour Stories, and follow people whose progress motivates you. JOIN STUDY ROOMS Focus alongside others in live study rooms, follow the leaderboard, and celebrate milestones together. CREATE AND SHARE RECAPS Turn your sessions into daily, weekly, or goal recap videos. Share sessions to Stories or your Feed, or export your recaps to other apps. YOUR VIDEOS, YOUR CHOICE Videos saved in LapseIn stay on your device unless you choose to share them. Delete individual Stories, Feed posts, saved recaps, or your account from the app at any time.
