About
IotaIota helps you learn the Greek of the New Testament the way seminaries teach it, in a few minutes a day.
Learn the words that appear most, parse real forms taken from the Greek New Testament and drill paradigms until they stick. Your progress keeps you going: a daily goal, a streak and a forecast of when you will finish your course.
FOLLOW YOUR CLASS
Pick the chapter order of popular textbooks such as Mounce's Basics of Biblical Greek (4th ed., including Track 2), Voelz, Black, Croy, Decker or Merkle and Plummer, or take our own Koine Path, ordered by how often each word appears in the New Testament. IotaIota is not affiliated with these books or their publishers.
GREEK FIRST, THEN YOUR APPS
Optional and free: every morning your other apps lock until you review your words in IotaIota (5 by default, up to 20). You choose how many words, the start time and which apps never lock. Calls and emergencies always work. It uses Apple's Screen Time, and your choices stay on your device.
FREE
- Vocabulary with spaced repetition: more than 1,100 words with English and Spanish glosses
- Reviews without limits
- New words every day, and more the longer your streak: from 5 up to 20 a day
- Daily goal, streak, activity map and finish-date forecast
- Community: join your class, church or study group with an invite code and see the weekly leaderboard
- Daily reminder
PREMIUM
- Parsing: nearly 5,000 real verb forms from the New Testament, checked field by field (tense, voice, mood, person and number)
