We took every major GRE app's tests ourselves and scored each on four things: how close the questions feel to the real exam, how much practice you get, whether you learn from your misses, and what it costs.
A note on bias: nerzia is our own product. It's ranked second below, and we've tried to be straight about where it falls short. Nothing here is affiliate-linked.
The rankings
These are real retired GRE questions from the people who write the exam — the most authentic practice that exists, and the truest benchmark of your score. The catch: there are only two free tests, and when you get a question wrong, you get nothing. No explanation, no lesson, just the next question.
Take these first, always. Then learn from your misses elsewhere.
Our own app — read this one with that in mind. What nothing else on this list offers: over a hundred tests that never repeat, a score prediction that updates live as you practice, and a step-by-step explanation for every single miss. It loses points for being iOS-only, and there are no video lessons.
The most practice of anything here, by a wide margin. Try it free →
The strongest teaching library of the paid apps — over 250 video lessons, and everything is explained well. But with only three practice tests, you'll run out of material right when you need repetitions most.
Best if you learn by watching, not just doing.
Five dollars a month is absurd value, and the verbal strategy teaching is the best around. There's no mobile app, though, and it's thin on actual practice tests.
Pair it with nerzia for a complete stack at about $15 a month.
The eight strategy guides are among the best GRE books ever written. The app is just a companion to them — no adaptive practice, nothing you'd open on its own.
Great books, forgettable app.
The classic classroom option: live classes, real instructors, structure and accountability. Also a $400 minimum, a fixed question bank, and no mobile app in 2026.
Only if price is truly no object.
The headline feature is the score guarantee: hit your target or get refunded. It's a real safety net — if you qualify. The conditions are strict, and the price is high for what the software itself does.
Read the fine print before you commit.
