Studo

hey everyone 👋 i’m vüsal, and i built studo. i kept procrastinating and losing track of my study time, so i made a simple tracker that visualizes every session on a github-style heatmap. once i saw the gaps, it became way harder to skip. free version → unlimited local timer + heatmap + session log with notes/images. pro version → cloud sync, analytics, pomodoro, blurting (write what you learned after a session), goal setting, flashcards with spaced repetition, and a leaderboard. i launched studo.space yesterday and even made my first sale on day one, which blew my mind. would love feedback from the ph community on what to improve next (ui/ux, features, or growth ideas). what do you think is the #1 feature a study tracker must have?
