■ 落ちものパズルで、化学反応を覚える 降ってくる元素やイオンを、となりに置いてつなげるだけ。 H と O がくっつけば −OH、そこに H がもう1つで H₂O。 結合手の数と電荷のつじつまが合ったときだけ、物質ができあがります。 覚えるのは「AとBをくっつけると何ができるか」。 教科書のページをめくるかわりに、手を動かして組み立てます。 ■ 収録範囲 無機・有機・高分子の反応 358件(図鑑掲載310件)、46ステージ。 ・原子から分子へ ・気体の製法とハロゲン ・金属、酸化物と工業的製法(接触法・オストワルト法・アンモニアソーダ法・溶鉱炉) ・酸と塩基、中和と塩 ・酸化還元とイオン化傾向(過マンガン酸カリウム・二クロム酸カリウム・ヨウ素滴定) ・金属イオンの沈殿と錯イオン(沈殿の色・系統分離) ・脂肪族(アルコールの酸化・エステル化・銀鏡反応・ヨードホルム反応) ・芳香族(ニトロ化・スルホン化・ジアゾ化・アゾ染料・クメン法) ・高分子(糖・アミノ酸・タンパク質の呈色反応・合成樹脂・ゴム・ビニロン) ※ 本作が扱うのは「反応」です。mol計算・化学平衡・電気化学・熱化学・結晶格子といった 理論化学の計算問題は収録していません。 ■ 見ればわかる形にしています ベンゼン環は六角形、グルコースは環、デンプンは環が3つつながった鎖。 用語だけを並べず、構造を絵で描いています。 沈殿は底に沈み、気体は上へ抜けていきます。色もそのまま。 ■ 思い出す練習ができます 眺めるだけでは「見ればわかる」で終わります。 ・ステージクリアごとに小テスト(3問)。生成物を隠して4択で答える ・図鑑の「テスト」ボタンで、覚えた反応の生成物を伏せ字にできる ・間違えた反応は記録され、次の小テストで優先的に出題される ・さらに、その材料が盤面に落ちやすくなる。忘れたころに手が触れます ■ 元素のキャラクター 46ステージそれぞれに、その単元の勘所を教えてくれる相手が出てきます。 ナトリウムは黄色い炎をまとい、フッ素はいちばん強い酸化力を誇り、 シリカゲルは水を飲みほす石として現れます。 主人公「モル」との短い会話から、各ステージが始まります。 ■ 料金 単元1〜3(14ステージ・図鑑93件)は無料。気体の製法まで丸ごと遊べます。 残りは買い切り¥500で全部開放されます。 ・追加課金なし ・サブスクなし ・広告なし ・ガチャなし ・スタミナなし(好きなだけ遊べます) ■ こんな人に ・無機化学の暗記が苦手で、手が止まっている ・沈殿の色や気体の製法がなかなか定着しない ・有機の反応系統を、系統として頭に入れたい ・すきま時間に、片手で復習したい

ChronoMap traces human history on a single world map and a single timeline. Move through time and the political map redraws itself, with events surfacing right where they happened. What was happening in China — or Japan — while Islam was spreading across the world? You can see it at a glance. ■ An animated atlas of 30,000 years 69 historical maps from 28,000 BC to the present. Press play and borders shift and flow. Switch between linear and logarithmic time scales to take in all thirty millennia at once. ■ 2,794 events and people, every one explained Every entry has a description, and major events have long-form commentary. Causes and consequences are linked, so one lookup leads naturally to the next. About 9,300 entries in total. ■ 52 narrated stories A thousand years of Rome, the Mongols, the Age of Exploration, the Onin War, the fall of the shogunate, the history of philosophy, the history of money, and a 16-volume story of Western art (584 works). The map flies to each scene, campaign routes extend, and borders change as chapters advance. Text-to-speech narration is supported. ■ Blank-map quizzes and drills Fill in a blank map: 195 countries with flags and capitals, Japan's 47 prefectures, 70 ritsuryo provinces, and historical maps from 500 BC to 1920. Drills for history, geography, and ethics offer year-entry and multiple-choice questions, filtered by era, region, and scope (favorites / missed questions). ■ Empires rising and falling Napoleon's France, the Japanese Empire. Guess how far the empire reaches next, tap the map, and watch the animated answer. ■ Relationship trees Eight themes — science, Western art, revolutions and nation-states, philosophy, Chinese history, Japanese history, the Islamic world, medieval Europe — laid out as chronological trees of people and events. ■ Collect cards, then review Answer quizzes correctly to collect event cards. Collected cards enter a spaced-repetition review queue (1 day → 3 days → a week → ...), with an optional daily reminder. ■ Geography built in Köppen climate zones, climographs for 80 cities, descriptions of the world's states and provinces, major rivers and landforms. ■ Search by place Type a place name and about 13,000 places match — cities, countries, regions, mountains, rivers, and historical states. Pick a city to see every power that ruled that spot through history (Paris: Rome → Francia → ... → France) and all events that happened there, across all eras. ■ Fully offline All data is bundled. Every feature works in airplane mode, from the first launch. ■ Japanese and English The entire app switches between Japanese and English with one tap. ■ Easy to trust - No ads, no in-app purchases, no account required - Your study records stay on your device and are never uploaded - No cookies, no identifiers * Historical borders and dates are simplified approximations for learning. Disputed regions and poorly documented eras are especially simplified. * Base map: Natural Earth / Historical borders: simplified from historical-basemaps (GPL-3.0) / Portraits and images: Wikipedia

Verdict
The clearest difference is monetization model: ChronoMap at free against Structura 元素合成 ― 化学反応を覚えるパズル's free with in-app purchases. ChronoMap also leads on update cadence (every 3 days vs weekly) and iOS requirement (15.0 vs 17.0). Structura 元素合成 ― 化学反応を覚えるパズル's advantage is review sentiment (100% vs 80%). On ads, in-app purchases and device support there is nothing between them.
