# Nature Bingo > Source: > Published: 2026-10-11 14:56:16+00:00 *This is a submission for the [Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass](https://dev.to/challenges/hacktoberfest-week1-2026-10-05)* Nature Bingo is a web app designed so that the best session is the shortest one: open it, get a quest, put the phone in your pocket, and go outside. You tell the app what you like (birds, plants, photography, hiking, mindfulness), how much time you have (5 to 60 minutes), and whether you're indoors or out. Gemma, an open-weight model, writes one short, safe nature quest for you, like "Listen and Count: stand still and note every different bird call you hear." Then you play in the real world: It's for anyone who wants a gentle nudge outside without another app competing for their attention: students, desk workers, families, and beginner birders or hikers.
