Who it is for
Anyone timing something short who wants the result to land in the conversation rather than on a separate device.
Digital or analog stopwatch shown in the chat
Overview
The app puts a working stopwatch into the conversation, with a choice between a digital readout and an analog face. When timing stops, the elapsed figure is passed back to the model, so the recorded duration becomes part of the thread.
That handback is what separates it from a phone stopwatch: the number does not have to be retyped before it can be discussed or used in a calculation. The example prompt in the listing is the single word analog, which selects the clock face.
Widget is the developer. Laps, countdowns, and saved timing history are not mentioned in the record.

The recorded time is returned to the model automatically, which is the difference from any standalone timer.
Availability
3-2-1 Go Stopwatch is listed in the ChatGPT apps directory only. Widget 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.

This is an independent catalogue entry compiled by Node8 from 3-2-1 Go Stopwatch's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Widget, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
