Should I Go Out?

Should I Go Out? answers one question and then gets out of your way. You tap once, and it checks the weather, the air quality, and the parks near you, then a Gemma model running on your own computer suggests a single outdoor plan that fits the time you have: a park or landmark, a round-trip route, a few things to do there, and what to wear. Then the screen tells you to put your phone away. No feed, no streaks, no leaderboard; goals only move when you check in at the park with "I’m here".

It is built for that free Saturday when you open your phone to find something to do and are still scrolling at sunset. The server measures everything it can measure, like real round-trip walking times, and only asks Gemma for the parts that need judgment, like which park fits and what to wear. Check-ins compare your location in the browser without sending it anywhere, and it works in English and Korean.

Vibe-coded evidence, in the author’s own words in the dev.to article: "I built this with Cursor agents, and Entire recorded the sessions and linked each one to its commit: 104 of the 126 commits carry an Entire-Checkpoint: trailer." GitHub stars: 0 at the 29 October 2026 check.

Honest limits: there is no public hosted demo, because the model runs on the author’s own Mac. To try it you clone the repository, pull the model, and run it yourself, and the Mac has to stay awake. The first answer takes 10 to 20 seconds while Gemma loads, and the author’s own testing found the app can still suggest a facility that sits just outside a park’s boundary.
