I built Astralis: Look Up – point your iPhone at the sky and see real 3D planets & the Moon with NASA textures

I kept wanting a clean way to just look up and instantly know what bright object I was facing without ads, accounts, or bloated features. So I built Astralis: Look Up. Point your phone at the sky and it shows the planet, star, or Moon you’re looking at as a real lit 3D sphere with NASA-derived textures and the correct current phase. You can save any of them as a full-screen wallpaper. Other things it does: • Tonight timeline – moonrise/set, planet times, stargazing score (real cloud c

AI 分析

痛点：星象识别类 App 普遍广告多、强制注册、功能臃肿，用户只想要「举起手机就知道那颗亮的是什么」的干净即开即用体验。

目标用户：iPhone 上的普通观星者与天文爱好者，尤其是反感广告、账号和订阅制、愿意一次性买断的隐私敏感用户。

证据：I kept wanting a clean way to just look up and instantly know what bright object I was facing without ads, accounts, or bloated features. … No account, no ads, no tracking. One-time $0.99.

变现：一次性买断 $0.99–$4.99 为主，叠加壁纸包/深空天体包/观星事件提醒等小额内购；也可做「买断 + 可选订阅高级天文事件推送」。

MVP：2 周内用 SwiftUI、ARKit 和开源 HYG 星表加简化行星算法，只做两件事：举起手机识别视野中最亮天体（含月球实时相位）和今晚可见行星升起落下时间表；无账号、无广告，一次性 $2.99，本地计算。

竞品：SkyView、Star Walk 2、Sky Guide、Stellarium Mobile、Night Sky

摘要：开发者发布 Astralis: Look Up，用 iPhone 对准天空即可看到带 NASA 纹理的 3D 行星与月球实时相位，全部基于 NASA JPL 轨道根数本地计算，无账号、无广告、无追踪，一次性 $0.99。还包含今晚时间线（月升月落、观星评分、火箭发射、真实 ISS 过境）、AR 指南针和 3D 太阳系仪。说明「无广告 + 买断制」的极简星象工具仍有独立开发者切入空间，但该赛道已被 SkyView、Star Walk 等成熟产品占据。
