Gemini CLI 2.0 vs Claude Code: app build comparison

Gemini CLI 2.0 and Claude Code receive the same task: build a focus time tracking app from a structured prompt and a Markdown product requirements document. The presenter places the PRD in each project folder, tells the coding assistant to reference it, then opens the generated app through a local development server. This tests work on local project files; the walkthrough does not establish that either tool runs its models locally or works offline.

The presenter reports that Gemini's app supports focus duration selection and a session tracking chart, but describes its interface as plain. Claude's version includes the core features plus day and night modes, and the presenter considers it more polished. Claude also finishes planning and implementation faster in this test. These are observations from one app build, rather than proof of a general performance ranking.

The suggested workflow assigns Claude larger features, architecture decisions and unclear debugging tasks, while Gemini handles repository summaries and small adjustments. The presenter shows how both tools can operate in the same project through separate terminal tabs. Although Gemini is described as suited to quick execution, its demonstrated build takes longer here. The comparison provides a practical example of task selection, without a measured benchmark suite or detailed cost comparison.
