Langua is the broader product and its review system is better than ours. Saygood is the faster one: voice straight to the model, a partner you wrote rather than a tutor voice you picked, and dials that move mid-call.
Spaced repetition drawn from what you actually said in a conversation is the best idea in this category and we do not have it. If breadth is what you are buying, buy Langua.
Also true, and we are not going to pretend otherwise. It has a recurring free tier, runs on Android and the web, and its entry plan undercuts us while its top plan matches us to the cent.
you want the study tools around the conversation, and a beat of latency between turns does not bother you.
you want the call to run at the speed a real one does.
A course is a good way to get your first few hundred words. The mistake is staying there for two years. Speaking is a separate skill from recognising, it is the slowest one to build, and the only way to build it is to talk to someone who is not waiting for you — as early as you possibly can.
I speak five languages and I have tried more or less everything under the sun to learn them — courses, flashcards, tutors, every app in this comparison set that I could get my hands on. The gap that never got closed by any of it was the same one every time: actually speaking, in real time, to someone who is not waiting for you. That is the only reason Saygood exists.
On the Unlimited tier ($29.99/mo or $199.99/yr on iOS), that is how it is sold. The Communicate tier below it is $19.99/$149.99. Check the current in-app terms — tier definitions in this category change more often than the prices do.
Latency, and how much of the conversation is yours. In Langua your turn has to be transcribed, then answered, then spoken, which puts a gap after you stop. And its controls sit outside the call: you choose a voice and a dialect beforehand. Saygood sends your voice to the model as voice, and slang, speed, patience, corrections and immersion are all dials you can move mid-sentence.
Langua, comfortably, and its spaced repetition is the single best feature any competitor in this comparison has. If reviewing vocabulary from your conversations matters to you, we have no equivalent.
Only if real time and control are what is blocking you. If a pause between turns does not bother you and you are happy with the tutor voices on offer, Langua gives you more product for less money and you should buy that.
Not today, and that is the honest answer — you open the app, pick someone, and talk. One is in build, and it is deliberately not another course: rather than a library of lessons, it works out what you can and cannot say from the calls you have already had, and steers the next conversation toward the gap without ever showing you a lesson screen. The first piece — a spoken level taken from a real five-minute conversation instead of a multiple-choice quiz — is due in August 2026. If that date moves, this page moves with it.
Yes, and it is the single most underrated thing in the app. Slang is a dial in Saygood — mostly clean, everyday, street, full slang — and you can move it in the middle of a call, along with speaking speed, how patient they are, and how hard they correct you. Courses teach the careful, neutral, written register almost exclusively, and that is not the register anybody speaks to you in. Learning only that version of a language is how people end up fluent on paper and lost in a bar.
Ten minutes of calling, free, no card. That is enough to find out whether talking to an AI partner does anything for you.
