Calendars are great at telling you when things happen, but terrible at accounting for the randomness of daily life. You open your calendar and fill the day with work, study, gym, etc. and end up having to move everything around when your friend asks you for a coffee at 2 PM. We wanted a calendar that works like a human planner: instead of making you micro-manage every slot, you tell it your ambitions and it builds the schedule for you around your other commitments. With the TIME theme in mind, we built CalVin that treats your time as the scarce resource it is and protects it.
