Set a countdown and check in before it runs out. Miss it, and CountdownTrigger automatically notifies the people and systems that need to know.Check in before it runs out. Miss it, and we alert the people who matter.
Arm a countdown. Check in to keep it quiet. Miss the deadline and your pre-armed actions fire — automatically, to the people and systems that need to know.
Pick a check-in window — minutes to weeks — or a fixed deadline. Then decide what fires if you miss it: email, SMS, or webhook.
A tap, an email link, an SMS reply, or an API call resets the timer to full. As long as you check in, nothing happens.
When the countdown hits zero, your pre-armed actions execute automatically — reaching every recipient and endpoint you set.
