Is Keeper.sh worth the price?

Good value

The Free tier is genuinely usable for light users with 2 accounts and 25 daily calls, though the 30-minute refresh and 3-connection cap will frustrate anyone coordinating more than a couple of calendars.

It is best for freelancers, consultants, and multi-calendar professionals who need fast, broad sync without paying enterprise rates.
