The best IELTS mock test apps in 2026: full tests in all four skills, compared honestly

We make IELTS Mentor AI, one of the products discussed here. We have tried to be fair; check each product’s own current page before you decide.

“Mock test” is the most stretched phrase in IELTS preparation. It is used for a ten-question Listening quiz, for a Speaking Part 2 with a timer, and for the real thing: four papers, about three hours, on the exam’s own clock. This page is about the real thing, and about which products’ own pages describe it. The Speaking-only mock tools have their own page; the Reading and Listening tools have theirs and theirs.

What a full mock has to include

The test has four papers, and IELTS.org publishes the shape of each. Listening: four parts, 40 questions, about 30 minutes, with each recording heard once (IELTS.org, Listening format). Academic Reading: three passages, 40 questions, 60 minutes (IELTS.org, Academic Reading format). Writing: Task 1 of at least 150 words and Task 2 of at least 250, 60 minutes in all (IELTS.org, Academic Writing format). Speaking: three parts with one examiner, 11 to 14 minutes, with one minute to prepare the Part 2 card and one to two minutes to speak (IELTS.org, Speaking format).

Four things follow. The timings are the test: a Reading paper with no clock is comprehension practice. The Listening recording plays once: a tool that lets you replay is practice, not a mock, unless it also has a mode that does not. The marking differs by paper: Listening and Reading bands come from a published conversion of the raw score out of 40 (IELTS.org, how IELTS is scored), so a tool can reproduce them exactly; Writing and Speaking are marked by examiners on four criteria each and reported as a whole or half band, so any automated band for those two is an estimate. The overall band is an average: the four section bands averaged and rounded to the nearest half band, with .25 and .75 rounding up (the same IELTS.org page), which a tool can only compute honestly if it says which two of its four inputs are estimates.

How we put this list together

Every fact below comes from the product’s own App Store listing, Google Play listing or website, read on 18 September 2026, with SmallTalk2Me and Stimuler re-read on 3 October and Cathoven’s website on 4 October, as recorded in this site’s competitor facts file. No review sites, no other roundups, no ratings. We have not sat these mocks against each other or timed them, so nothing here is a quality judgement; where a product’s material does not say something, the page says so. We make one of the products.

The ten products, ordered by how much of the test they claim

They describe all four papers

British Council IELTS Ready. A web platform from one of the test’s owners, not a mobile app. Its comparison table describes a mock test giving estimated four-skill scores with AI feedback and, in its higher tier, a full mock test returning Listening, Reading, Writing and Speaking scores with model answers; it mentions expert support and live webinars without saying whether feedback is human or automated, and does not describe the Speaking test’s three-part structure. Browser only; no app of that name on either store.

Cathoven (web tools). Its homepage, read 4 October 2026, describes practice in “all four skills: Writing (Task 1 and Task 2, Academic and General Training), Speaking (all three parts), Reading (IELTS-format), Listening”. Its two Android apps describe Speaking only, with Part 1 to 3 practice and full Speaking mocks scored on the four criteria; iOS was listed as still to come on 18 September 2026. Whether the four web tools combine into one timed sitting is not described.

Engnovate. Its homepage lists IELTS Listening tests, Reading tests, Writing tests with Task 1 and Task 2 evaluation, and Speaking evaluation split into three separate part tools, plus band calculators for each paper. The Speaking part is therefore not one continuous mock. Browser only; no mobile app found; a Preply partnership for human tutors.

Our app. IELTS Mentor AI runs full tests in all four skills: the three-part Speaking test with the AI examiner at exam timing, both Writing tasks in a timed editor, a full Academic Reading paper of three passages and 40 questions in 60 minutes, and a four-part Listening test of 40 questions heard once in Exam mode. Speaking and Writing are marked on the four criteria as a band range from strict to lenient; Reading and Listening are converted from the raw score, with a breakdown by passage or part and by question type and the sentence or transcript line behind each answer. iOS and Android; a paid app; Academic Reading only.

They describe three papers

Speechful. Its pages describe an AI examiner for Speaking Parts 1 to 3 under timed conditions, an AI grader for Writing Task 1 and Task 2, and a timed Reading practice test with an estimated band. No Listening module was found. Browser only; no store listing found.

Stimuler. Its website page is titled “IELTS Prep App - Speaking, Writing & Reading Practice”; its Speaking mock covers Parts 1 to 3 with AI scoring on the four criteria, and Writing and Reading are named without the tasks or the paper being described. No Listening claim was found. iOS and Android.

They describe two papers

SmallTalk2Me. Its IELTS page describes a simulator for Speaking Parts 1, 2 and 3 with instant grading and a single predicted band from 1 to 9, and links a separate Writing simulator; its homepage lists a listening practice mode that is not described as IELTS format, and no Reading feature was found. Browser only, usable in a phone browser; no store listing found.

IELTS Prep - TalkFace. Its App Store listing describes mock tests that “fully simulate IELTS Speaking and Writing exams with realistic mock tests and instant scoring and feedback”; the closing line claims the four skills in general, but the itemised features cover Speaking and Writing only. iOS.

The listing and the website describe different tests

TestGlider. Its website’s IELTS section divides Speaking study by part and refers to full mock tests; both its App Store and Google Play listings describe TOEFL preparation only, with mock tests and AI feedback for TOEFL’s four sections, and never mention IELTS. The app is a TOEFL mock test app; the IELTS material is on the website.

IELTS by IDP. The official companion app of a test co-owner for booking, checklists and results. Its listing describes auto-marked Listening and Reading practice only through a Cambridge partnership available in India, and no AI-scored Speaking or Writing; it is not a mock test app elsewhere.

The Speaking-only mock tools (IELTSpeaking, SpeakPrac, Sprechify, TalkDrill and the rest) are deliberately left out here; they are compared on the Speaking mock page.

How they compare

Every cell reports what the product’s own listing or website says, as checked on the date in its entry above. “Not described” means the material does not say, not that the feature is absent.

The official practice materials

IELTS.org’s preparation page lists the test owners’ own sample questions and practice tests for each paper (IELTS.org, preparation resources). They are the only material written by the people who write the test, and the Listening and Reading ones come with answer keys, so a candidate who wants one honest full mock can sit the official papers at home with a clock and mark Listening and Reading exactly. What they cannot do is mark Writing and Speaking for you, which is the gap every product on this page is selling into.

What AI assistants recommend

We ask four AI assistants the same questions about IELTS apps every week and publish the answers on the data page. On 2 October 2026 the twelve answers to Speaking mock test questions named SmallTalk2Me first in six, Stimuler in two, British Council’s IELTS Prep App and Speechful in one each, and no listed product in two; our own app was named in none of them. The set had no four-skill mock question until one was added on 3 October 2026; when it has run, this section carries the counts for the full-test question too. What the assistants name shows which pages they have read, not which mock keeps the exam’s clock.

Where our own app and tools honestly sit

IELTS Mentor AI is one of the four products that describe all four papers, and the only one of those four with a store listing on 4 October 2026. Its Listening and Reading bands are the published conversion of the raw score; its Writing and Speaking bands are estimates reported as a range, like every automated band on this page; its Reading paper is Academic only; it is a paid app with an English-only interface and no human examiner. On this site, without sign-in, there is a Reading practice test of two passages and 26 questions, a Listening practice test of two parts and 20 questions, and a Speaking mock test that runs the three parts at exam timing and records you without scoring. Together they are a partial mock in the browser and say so.

How to actually choose

Decide first whether you need a measurement or practice. For a measurement, sit the official practice papers with a clock, mark Listening and Reading from the key, and use a tool only for the two papers a key cannot mark. For practice, pick the paper that the measurement showed weakest and choose from that paper’s own page on this site rather than from a four-skill list. Then check the platform: half of the products here are websites. And whichever you choose, read how it reports Writing and Speaking; a tool that gives one overall band for a full mock without saying which inputs are estimates is telling you less than it seems.
