ComparePad
Read full descriptionHide full description
ComparePad is a calm notebook for criteria-based comparison and judgment. Instead of picking a preset answer, you show the rule behind your decision. Choose a comparison mode, define your criteria, write reasons, and save one Compare Card that captures your thinking. Modes include: • Same / Different • Better for... • Sort by One Rule • Sort by Two Rules • Change One Thing, Compare Again Each session creates a locked Compare Card containing your concepts, decisions, written reasons, summary sentence, and reflection. All cards are stored locally in your Library so you can revisit how your rules and judgments evolve over time. ComparePad is fully offline. No accounts, tracking, ads, or generated answers.
Lemma Box

Lemma Box is a private offline vocab desk — file word decks, lemmas, and flashcards, then find any card before the quiz.

Verdict
ComparePad and Lemma Box are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
