Cal.day as a concise brand name for scheduling apps: does simplicity drive user trust and adoption?

I've been thinking about how critical a strong, memorable domain is for startups in the productivity tools space, especially calendar or scheduling apps. A name that is short, easy to type, and meaningful can instantly convey the app's purpose and build trust.

For example, Cal.day is a clever, compact domain that suggests calendar functions while maintaining brevity. It blends familiarity with novelty, which might make it easier for users to remember and recommend.

How important do you think domain names are in your experience when choosing or trusting scheduling software? Would a domain like Cal.day influence your perception or usage? Interested to hear different perspectives.
