Hi Product Hunt! I built English Logic for Japanese beginners who feel that memorizing isolated words and grammar rules is not enough. The core idea is simple: make the logic visible. The app helps learners reason from meaningful word parts, assemble English sentences in natural order, notice sound patterns, and review at the right time. Educational quality was the hardest part. Etymology, morpheme analysis, Japanese meanings, and examples are not generated from guesses. Content is promoted into lessons only after source, license, confidence, and automated validation checks; low-confidence candidates remain isolated. The full learning experience is free. Free users may see a non-personalized interstitial after a completed block of 10 questions, while an optional subscription removes ads. Progress is saved before any ad appears. English Logic currently focuses on Japanese learners and is available for iPhone and iPad. I would love feedback on the learning flow and on which English patterns you want explained next.
