HOW IT WORKS

Get started in minutes

1

Create a countdown

Define your check-in interval—daily, weekly, or custom. Add the actions you want triggered if time runs out.

2

Check in regularly

Reset your timer via dashboard, email link, SMS, or API. Each check-in extends your deadline.

3

Actions trigger automatically

Miss a check-in and your configured emails, SMS messages, or webhooks fire—no questions asked.
