Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Relativity Simulator
Read full descriptionHide full description
Relativity Simulator is an interactive relativity toolkit built strictly on the axiomatic foundations of modern physics. There is no "hard sci-fi" here — every result traces back to the Lorentz transformation of special relativity or the Einstein field equations of general relativity, and is verified against numerical truth fixtures. 【Real physics, not imagination】 · 20 interactive modules covering core effects from special relativity to black holes, gravitational waves, and curved spacetime; · Each module ships with precise charts, adjustable parameters, and a "Theory Card" with a fully visible derivation chain; · All demo numbers are recomputed locally on your device from real CODATA constants — nothing is fabricated. 【Phenomena you can verify yourself】 · Gravitational time dilation: why clocks run faster up high — ~80 ns/day faster atop Everest, ~38 µs/day faster on GPS satellites; · Twin paradox: fly to 4.22 light-years at 0.8c and the Earth twin ages 10.5 years while the traveler ages only 6.3; · Tidal disruption: why you get stretched into "spaghetti" falling into a black hole — small holes tear you outside the horizon, supermassive ones only after you cross it; · Plus light bending, gravitational lensing, the Schwarzschild horizon, frame dragging, and mass–energy equivalence E=mc². 【Built for learning and teaching】 · Volume-based progression: kinematics → gravitational field → black holes → cosmology → applications; · Bilingual (zh/en) system notes ship with every effect: derivation, physical quantities, and references; · Chinese / English UI follows your system language. 【Privacy first】 The app collects, stores, and transmits no personal data, embeds no third-party SDKs, and runs every computation locally on your device. Whether you are studying, teaching, or simply curious, Relativity Simulator lets you actually run the "invisible spacetime" and watch it.

一颗钻石原石,可以怎样规划成不同的成品? 钻石原石规划向导通过可操作的三维教学案例,帮助珠宝学习者、从业者和对钻石加工感兴趣的用户,理解原石外形、切割面、模拟内含物与成品组合之间的关系。 从五颗教学原石开始,选择琢型、成品粒数和规划目标,由 SUVA 规划引擎在本机计算方案。比较成品重量、保重率、最大主石与模拟估值,再动手改变切面,观察一次调整如何影响结果。 主要功能: • 五颗程序生成的教学原石,覆盖不同外形与模拟内含物分布。 • 八种琢型,每次最多规划四粒成品。 • 比较价值、保重与主石目标,查看不同成品组合。 • 旋转和缩放三维模型,拖动切面或用按钮逐步精调。 • 还原为计算结果,并可撤销这次还原。 • 逐刀查看锯切、料块分离与抛光成品。 • 内置学习指南,通过对照练习理解方案取舍。 核心功能无需注册、无需 PC 软件,在设备本机完成计算。适用于 iPhone 与 iPad。 使用范围:本 App 使用教学案例和模拟内含物,当前不导入真实扫描、不保存项目;切换原石或关闭 App 后,手动调整可能不再保留。净度、比例等级、价格及汇率采用简化教学模型,结果仅供学习与方案比较,不构成鉴定、报价、交易或实际加工依据。 由苏州苏哇科技有限公司开发。

Verdict
The clearest difference is iOS requirement: Relativity Simulator at 17.0 against 钻石原石规划向导's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
