LadderTouchLite is an app to learn the basics of ladder logic, which is a graphical programming language. This app has two functions. You can learn about that mechanism by executing some of the prepared samples. And you can check your understanding with questions. -------Difference from the full version------- It doesn't show hints of questions. You cannot make your own ladders. ---------------ELEMENTS--------------- Input(yellow) Up to 5 elements. You can control the input signal by tapping the buttons at the bottom of the display. Virtual output(red) Up to 5 elements. Internal memory(gray) Up to 20 elements. Virtual output(red) and internal memory(gray) are the same for logical behavior. But the difference is in usage. The virtual output is the last element in the ladder logic chain. The Internal memory is for the processing element of the ladder logic chain. These are an imitation of the actual ladder logic with the output devices. Timer(blue) Up to 5 elements. The timer can be set from 0.1 seconds to 10.0 seconds. The setting unit is 0.1 second. The timer works only 'on delay'. This app does not include 'off delay'. On Delay. ---++++++++++ source -------++++++ destination Off Delay. +++---------- source ++++++++----- destination + ON - OFF Time flows from left to right Counter(green) Up to 5 elements. You can set from 1 to 50. There is no counter reset element in this app. Many other ladder logic software has it. The way to reset the counter is to stop running the ladder. All elements can be inverse in the source area. However, timers and counters cannot do it in the destination area. It is difficult to understand the inverse logic of a timer and counter in the destination area. --------------Other-------------- There is no function that connects to outer devices.

現場で思いついたラダー回路を、その場で描いて、メモごと残しておけます。 ■ 起動したら、まず回路の一覧 これまでに描いた回路が、名前とメモと日付で並びます。 「あのとき何を考えて組んだのか」を、開く前に思い出せます。 ■ 回路にメモを残せます 回路ぜんたいへのメモと、部品ひとつずつへのコメント。 どちらも後から検索できます。 ■ 探せます 回路の名前、メモ、部品のコメント、使ったデバイス名(X0 や Y10 など)から探せます。 ■ 描いて、その場で動かせます a接点・b接点・コイルを置いて、縦の線でつないで並列にできます。 入力を切り替えると、通電している線とONになったコイルがその場で分かります。 ■ 現場の外には持ち出しません 保存はすべて端末の中です。アカウント登録も、広告もありません。アプリ内課金のお支払いはお使いの端末とAppleの間で処理され、当方が内容に触れることはありません。 ■ 回路の保存数だけ買い切りで増やせます 描くこと、メモを残すこと、探すことは無料のまま全部使えます。保存できる回路の数だけに上限があり、上限をなくすアプリ内課金があります。月々の支払いは発生せず、上限に達しても、既にある回路の編集・保存はそのまま行えます。 [対応していないもの] タイマ・カウンタ、書き出し、クラウド同期には対応していません。 [ご注意] 本アプリは実機のPLCとは接続しません。画面上の動作は本アプリの論理モデルによる模擬です。 実際の設備の設計・運用の判断は、必ず実機と各メーカーの資料でご確認ください。

Verdict
The clearest difference is update cadence: ラダー図ノート at every 9 days against LadderTouchLite's every 2 months. LadderTouchLite's advantage is iOS requirement (15.5 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
