Trailhead: Gemma 3 plans your walk on your own laptop - then gets you off the screen
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass . What I Built Trailhead is a local-first Streamlit app that turns a few taps into a short outdoor outing — and then deliberately gets out of your way. You pick three things: an activity (walk, run, hike, birding, nature observation, photography), how much time you have (15 min to 3 hours), and where you are…
Trailhead is a local-first app for smartphones that turns a few taps into an outdoor outing. Users can choose an activity, the amount of time they have, and their location. The app then pulls live weather and daylight information from Open-Meteo and uses the locally running Gemma 3 4B model via Ollama to generate a route suggestion in plain language.
The route suggestion is deliberately simple, without invented trail names or fake map data. The app also provides seasonal highlights for the current latitude, three off-screen challenges like sitting silently and counting sounds, and a safety note based on actual conditions. Users can download the card as a self-contained HTML file or a PDF, or hit "Take me outside" for a single line of instructions and a return time.
The app is designed to be offline and store data locally in SQLite. The goal is to get users outside in under 60 seconds, then take them on their walk.
