Exploris vs 小狐化学实验室

Learn the world's countries, capitals and geography with Exploris: an interactive 3D globe that reproduces the view of Earth from space. No distortion, no ads, no tracking. WHY EXPLORIS IS DIFFERENT · A real 3D globe — appreciate the true size of countries, something flat maps can never show you. · 6 game types — from recognizing a country on the map to pointing out its capital: practice in many ways and challenge yourself to the max. · Adaptive Adventure mode — a smart algorithm that adapts to what you know, reinforces your weak spots and helps you learn by combining the different game types. · A passport full of stamps — your progress takes shape as a grid of levels and continents. Fill the passport as you level up. · 195 countries recognized by the United Nations — the world's most accepted standard. You can also explore disputed territories and dependencies on the globe. · 32 languages — verified data from authoritative sources: names, capitals, currencies, languages, demonyms and much more. · No ads, no personal data — your progress lives only on your device. Works offline. HOW IT WORKS Explore — spin the globe, tap countries and discover info cards with flag, capital, population, area, currency, languages, HDI and a direct link to Wikipedia. Play — start with Adventure mode. The algorithm proposes questions adapted to your progress and combines different game types so you learn without getting bored. Passport — earn stamps by completing tests with no mistakes. Climb from Tourist to Backpacker, and from Backpacker to Guide, on each continent. Your goal: fill the passport. WHO IT'S FOR Designed for kids and teenagers from 8 to 15, but so engaging it will hook adults curious about the world too. DATA SOURCES Verified public data from the United Nations, Natural Earth, the World Bank and Wikidata. The app silently checks for newer data in the background and updates automatically. PRIVACY Exploris does not collect any personal data. No accounts, no tracking, no ads. Your progress lives only on your device. Download Exploris and start filling your passport!

小狐化学实验室是一款面向中学生的化学实验学习工具，围绕常见中考化学实验，把实验步骤、实验现象、化学方程式、易错点和微观原理整合到一个可交互的学习流程中。 主要功能： 1. 化学实验训练 覆盖制取氧气、制取二氧化碳、粗盐过滤、蒸发结晶、金属活动性、酸碱盐反应等中学常见实验。每个实验包含仪器选择、操作顺序、现象判断和扣分点训练。 2. 实验原理微观分析 用粒子视角解释实验背后的变化，例如过氧化氢分解生成氧气、碳酸盐与酸反应产生二氧化碳、粗盐过滤中的分离过程等，帮助学生从“背结论”走向“理解为什么”。 3. 3D 可视化学 提供轨道杂化、σ键/π键、甲烷空间构型、VSEPR模型、离子晶格溶解等可视化模块，把抽象化学概念变成可以观察和对照理解的模型。 4. 学习进度与错因记录 记录实验掌握情况、练习结果和错因，方便学生复习薄弱环节。 适合： - 初中化学实验复习 - 中考实验操作与实验题训练 - 想用可视化方式理解化学概念的学生 - 家长和老师辅助讲解实验原理 Privacy Policy: http://mindkey.xyz/index.php/mindkey/privacy-policy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
