論理回路って結局どういうこと?を、頭じゃなく指先で理解するアプリです。 高校の情報Ⅰで学ぶAND・OR・NOTの3つの論理ゲートだけを使い、画面上でゲートをドラッグして配置し、配線をつなげて回路を組み立てます。入力をタップして0と1を切り替えると、その瞬間に配線が色を変えて信号が流れていく様子がアニメーションで見えるので、なぜこの出力になるのかが感覚的にわかります。 ■ こんな学び方ができます ・チュートリアルで各ゲートの性質を1つずつ体感 ・真理値表を見ながら回路の出力を予測する問題 ・条件に合う回路を自分で組み立てる問題 ・わざと間違えた回路を直すデバッグ問題 ・最小のゲート数で回路を組む発展チャレンジ ■ フリー作成モード ステージクリアだけでなく、制限のない「フリー作成モード」も搭載。ゲート数や回路の形に制約はなく、思いついた条件やアイデアをそのまま回路にして、真理値表で結果を確かめられます。授業の予習・復習はもちろん、「こんな回路を作ったらどうなるだろう」という自由研究的な使い方にも向いています。 ■ 料金について 基本機能はすべて無料でお使いいただけます。アプリ内には広告を表示しておりますが、広告を非表示にするオプションもご用意しています。これはアプリの継続的な開発・保守運営のための任意の課金であり、学習機能そのものはすべて無料範囲でご利用いただけます。 情報Ⅰの授業対策や定期テスト対策、共通テスト対策、プログラミング的思考の入り口として、ぜひ触って学んでみてください。

Verdict

The call

The clearest difference is ads: LogicGate at none against ロジックサーキット's shown. ロジックサーキット's advantage is update cadence (every 5 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
