Put the Phone Down. The Sky Has Something to Show You.

说明与用途

Look Up 是一个离线 PWA，帮助初学者在没有相机或网络的情况下识别夜空中的天体，鼓励他们用裸眼观察天空。

问题

Stargazing apps require a bright screen held up to the sky, making it hard for beginners to learn to look up without the phone.

结果

Look Up enables beginners to identify sky objects offline, reduces reliance on a bright screen, and encourages learning to look up with the naked eye.

工作流

• 1. Show tonight list with direction, height and best time in plain words.
• 2. Start a quest as a puzzle with optional hints.
• 3. Use phone’s compass and tilt sensors to point and check alignment.
• 4. Ask the local AI guide questions about the target.
• 5. When found, display a fact and a 30‑second countdown to look up.
• 6. Encourage users to stop relying on the app.

证据

Every stargazing app I tried had the same problem: to see the sky, you stare at a bright screen held up against the sky.

来源

Look Up is an offline night-sky field guide built around one idea: phone down, look up.

来源

It tells you what is worth seeing tonight from where you stand, with direction, height, and best time.

来源

When you find something, the app gives you a fact and a 30-second countdown that asks you to put the phone away and just look.

来源

The AI is a small open-weight language model runs inside the browser, offline, and answers questions about the target.

来源

The model never calculates a position and never supplies a fact.

I took Look Up outside for about 15 minutes… The sky was barely there… I could see two to four stars…
