Date Stopper 2.4

Date Stopper (by undefined) is a simple, powerful tool for taking control of your time. It lets you set blackout dates and pause your availability across your calendars in seconds—so you can protect focus time, holidays, or personal commitments without juggling settings or sending manual replies.

Key features:

• One-tap blackout: Instantly mark any date or range as unavailable.
• Smart rules: Create recurring blocks (e.g., every Friday afternoon or the last week of the month).
• Auto-decline and messaging: Automatically decline new invites and send a polite, customizable response.
• Conflict protection: Prevent double-booking by holding time across overlapping calendars.
• Shared blackout windows: Share protected dates with teammates or family to coordinate plans.
• Works with your existing calendar: Syncs with popular calendar services and respects your current events and reminders.

Ideal for anyone who needs clear boundaries—freelancers, managers, event planners, parents, and students—Date Stopper helps you say “not available” confidently and consistently, without the back-and-forth.
