Koine vs Koinetic

Koine is a Koine Greek vocabulary and Bible (NT) study app for anyone looking to deepen their knowledge of the language that backs the Word of God. Moreover, and I think more importantly, this app aims to enlighten the berean around the two streams of Greek texts, the differences between them, and how they have shaped the translated Bibles we have today. All features are available offline, no internet connection required. Build custom vocabulary decks and study with FSRS — a modern spaced repetition algorithm that adapts to your actual retention rate, scheduling cards at the optimal moment for long-term memory. It outperforms older Leitner-style systems by modeling forgetting curves per card. Add any word to a deck directly from the reader — no switching between apps. Search all 5,000+ Greek NT words by lemma, transliteration, or English definition. Filter by part of speech, frequency, and more. See every inflected form, its parsing, and all NT verses where it occurs.
