Nature Quest: an on-device open AI that sends you outside and gets out of your way

Description and use

Nature Quest delivers short outdoor missions via an on‑device AI, minimizing screen time and operating offline.

Problem

Users want outdoor activities without prolonged screen time, but most AI‑for‑outdoors apps keep users staring at a screen.

Outcome

Nature Quest delivers short outdoor missions via an on‑device AI, minimizes screen time, works offline, and keeps user data local, achieving the "Touch Grass" challenge goal.

Workflow

• Tap the app once
• Open‑weight AI model selects a quest from a 114‑quest library
• App displays title, purpose, task, and time, then says "Your quest is ready. Now put the phone away." and dims
• User goes outside and completes the quest
• User returns, app asks for outcome, optional photo, and records journal entry
• App updates streak and achievements and ends the session

Evidence

Nature Quest is built the other way round: the screen is the shortest part of the experience.

Quests come from a library of 114 hand‑checked missions. An open‑weight model on the phone picks the one that fits you.

The app says "Your quest is ready. Now put the phone away." and dims itself.

I started by having a small language model write every quest on the phone. On my mid‑range Android phone ... Qwen2.5‑0.5B loaded in about 19 seconds, took about 15 seconds to produce a first word, and then wrote around 0.3 tokens per second.
