Excellent - clean, flexible, powerful.

Pros
— Clean, simple, highly legible interface
— Ability to track multiple events
— Ability to use date or date/time as needed
— Notifications Integration

Cons
— For some reason, iCloud Sync wouldn’t work on my MacBookPro until I signed out of the account and signed back in.

Summary - Does just what I need, and well worth the $0.99 to unlock the unlimited date range functionality.
