Anyone timing focused work, cooking, exercise, or a meeting segment who wants the countdown visible.
30 Minute Timer
Countdown timers with sound and display options
Overview
What 30 Minute Timer does
30 Minute Timer, from Pershin D, starts countdown timers in a ChatGPT conversation and can also produce a standalone fullscreen timer page that persists as a link.
Durations are set in minutes or seconds. The listing names a number of adjustable settings: background image, progress icon, the text shown when time runs out, the sound family used for alerts, an optional alert at the halfway point, and whether the end sound repeats. Running timers can be paused, resumed, stopped, or restarted.
The sample prompts include a ten second countdown with a halfway alert alongside the thirty minute case.
What stands out
Alongside in chat timers it produces a fullscreen timer link that stays available outside the conversation.

Where 30 Minute Timer is listed
30 Minute Timer is listed in the ChatGPT apps directory only. Pershin D has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
