Hey Product Hunt! I’m Jakub, a software developer and Japanese learner. I built Kaname to make grammar practice feel manageable and help learners get comfortable using patterns in real sentences. It tracks four skills separately: recognizing a pattern, filling in a gap, telling similar patterns apart, and writing your own sentence. Reviews focus on where you need more practice. For example, if you recognize a pattern but confuse it with another one, you’ll get more comparison exercises. Kaname covers JLPT N5–N1, and core study works offline. All N5 content is free. Higher levels are one-time purchases; optional AI sentence analysis has a separate subscription. For the launch, the full N4–N1 bundle is about 25% off with code `KANAME30BGZPDRDARJM2`, valid through October 31, 2026 (Pacific Time). There are 500 redemptions in total, shared across Product Hunt, Reddit, and WaniKani. [Claim the launch offer](https://apps.apple.com/redeem?ct...) I’d love to hear how you currently practice grammar and what you find hardest about using it. Feedback on the exercises and explanations would be especially helpful :)
