Search "best app for learning biblical Greek" and you get two kinds of results: listicles that rank whoever pays the most affiliate commission, and forum threads where ten people name ten different tools and argue. Neither tells you the one thing you actually need to know: which tool fits the way you want to learn, and what each one is genuinely bad at.

So here is the honest version. Full disclosure up front: we make MasteryHelp, one of the tools on this list. We did not rank it first — the honest answer is that it isn't the #1 pick for most people, and pretending otherwise would make this whole post worthless. What it is best at, we'll be specific about. Everything below is written to help you pick correctly, including picking something that isn't us.

First: There Is No Single "Best" — There Are Different Jobs

"Learn Greek" hides at least four different jobs, and the best tool depends entirely on which one you mean:

Almost every tool is excellent at one or two of these and weak at the rest. The mistake is expecting one app to do all four. With that framing, here's the field.

The Comparison

1. Biblingo — Best Overall, Most Complete

Biblingo is the closest thing to a complete "learn the biblical languages" ecosystem. It covers both Greek and Hebrew, runs a real structured curriculum, and — unusually — includes listening and speaking through an immersion method, not just reading and recognition. If you want one polished app that takes you from nothing toward genuine language ability and you're willing to pay a monthly subscription for it, this is the category leader, and saying otherwise would be dishonest.

Where it falls short: the immersion approach isn't for everyone — some learners want explicit grammar explanation more than guided immersion, and the breadth means you're paying for Hebrew features even if you only want Greek. It's a subscription (tiered; check current pricing on their site), so it's an ongoing cost, not a one-time purchase.

Pick it if: you want the most complete single app and you value listening/speaking immersion.

2. MasteryHelp — Best for Vocabulary Retention and Reaching Reading

This is us, and here's the honest pitch. The single biggest reason people stall in Greek is not grammar — it's that they forget the vocabulary, so reading stays slow and painful and they quit. MasteryHelp is built specifically to fix that. It uses spaced repetition with a true mastery-learning gate — you don't advance until the material is actually retained, not just seen once — plus audio on every card and a reading track built around comprehension, not translation drills.

The thing that distinguishes it from generic flashcard apps is the engine: it's a retention system, not a deck you grind. It tracks whether words are genuinely sticking over weeks and months and weaves older vocabulary back in so your foundation doesn't quietly rot while you learn new material. It covers both Greek and Hebrew. (More on the method in how to actually remember Greek vocabulary.)

Where it falls short — honestly: it is not the deep grammar reference a full textbook is, and it does not do conversational/spoken immersion the way Biblingo does. It's a younger, more focused product than the big ecosystems. If your goal is to speak reconstructed Koine, it's the wrong tool.

Pick it if: you keep forgetting vocabulary, you want a system that gets words into long-term memory and carries you toward reading the New Testament without re-learning the same words every few months.

3. Daily Dose of Greek — Best Free Resource

Rob Plummer's Daily Dose of Greek is a gift to the community and it is completely free. The core is a two-minute video, five days a week, walking through a single Greek verse — plus full video lecture series (one keyed to a standard grammar, one to Plummer's own textbook) and free apps. There's a Daily Dose of Hebrew (and Aramaic, and Latin) too. For the price of nothing, it's one of the best ways to learn the grammar from a real teacher and keep your Greek warm day to day.

Where it falls short: it's instruction, not a retention engine. There's no spaced-repetition system tracking your individual vocabulary, no mastery gating, no personalized review schedule. You'll learn from it, but you need something else to make sure the vocabulary actually sticks.

Pick it if: you want excellent free instruction and daily accountability — and pair it with a real SRS for vocabulary.

4. Bill Mounce's Resources — The Textbook Standard

For decades, Basics of Biblical Greek has been the default first-year textbook, and the Mounce ecosystem around it is enormous: the grammar itself, vocabulary cards, the free FlashWorks flashcard software, the FlashGreek app, and paid online video classes (a one-time cost for time-limited access). If you want the traditional, rigorous, grammar-first path that thousands of seminary students have walked, this is it.

Where it falls short: it's a textbook-centered system, which means the burden of scheduling, reviewing, and not-forgetting is largely on you. The flashcard tools are solid but conventional — they don't adapt to your forgetting curve the way a modern SRS does. It's a curriculum, not a coach.

Pick it if: you learn well from a structured textbook and want the established, battle-tested grammar path.

5. Logos Mobile Education — Most Comprehensive (and Most Expensive)

Logos' Mobile Ed courses are seminary-grade: full video courses taught by recognized scholars, certificate programs, deep integration with the Logos Bible Software library. If you already live inside Logos and want academic-depth instruction, it's powerful.

Where it falls short: cost. Mobile Ed courses are a significant investment — often hundreds of dollars — and they assume (or pull you toward) the broader Logos ecosystem, which is its own substantial expense. It's overkill for someone who just wants to learn to read the Greek NT, and like the others it's instruction rather than a retention engine.

Pick it if: you want academic-grade courses, you're already a Logos user, and budget isn't the constraint.

6. Anki — Most Powerful, Least Hand-Holding

Anki is the free, open-source spaced-repetition workhorse, and its algorithm is genuinely excellent. There are community-made Greek vocabulary decks you can download today. For a certain kind of disciplined, technical learner, Anki plus a textbook is an unbeatable combination at zero cost.

Where it falls short: it's a blank engine, not a course. No curriculum, no gating, no guidance on what to learn or in what order — and shared decks vary wildly in quality. You have to build or vet your own content, tune your own settings, and supply all the structure yourself. Most people bounce off it for exactly that reason.

Pick it if: you're self-directed, technical, want maximum power for free, and don't mind doing the setup work yourself.

What About Duolingo?

Short answer: Duolingo does not teach biblical Greek. It offers Modern Greek, which differs from Koine in pronunciation, vocabulary, and a good deal of grammar — so it won't get you reading the New Testament. (If you're fuzzy on why, see Koine Greek vs. Modern Greek.) It's a wonderful app for what it does; reading the GNT just isn't one of those things.

The Honest Rankings, by Goal

Overall, if forced to rank for the typical learner who wants one app to carry most of the load:

  1. Biblingo — most complete, best all-rounder (paid).
  2. MasteryHelp — best for retention and reaching reading (that's us).
  3. Daily Dose of Greek — best free instruction.
  4. Bill Mounce — best traditional textbook path.
  5. Logos Mobile Ed — most comprehensive, highest cost.
  6. Anki — most powerful DIY, least structure.

But "best overall" is the wrong question. Sorted by your actual goal:

The Combination Most People Actually Want

Here's the thing the listicles won't tell you because it doesn't crown a single winner: the strongest setup is usually two tools, not one. A source of grammar instruction (a textbook, Mounce, or Daily Dose's free lectures) paired with a serious retention engine (MasteryHelp, or Anki if you're the DIY type) covers the two jobs that matter most — learning the grammar and never losing the vocabulary. Add the daily accountability of Daily Dose and you've got instruction, retention, and consistency covered for very little money.

If you want a single all-in-one and you'll pay for it, Biblingo. If your specific bottleneck is that you keep forgetting words and can't get to fluent reading — which is the most common way people stall — that's the exact problem MasteryHelp was built to solve, and it's why we built it. Either way, the worst choice is the one you abandon in three weeks. Pick the one that matches how you actually learn, and start.
