Bubble Calendar is a fresh new way to visualize your schedule as bubbles. Each bubble holds your day. The inner dot represents morning events, the outer dot represents afternoon events. The bigger the bubble, the busier the day. Just type naturally and it recognizes the date and time automatically. Try "Dance class Thu 7:30pm" or "Dentist tomorrow" — it just works. A Monday-first week layout lets you see your entire schedule at a glance.
