10 Best IELTS Preparation Apps in 2026 (Android & iPhone)

Your phone is where your spare minutes live — commutes, queues, lunch breaks. The right IELTS app turns those minutes into band-score progress, while the wrong one just sells you vocabulary flashcards.

We tested the leading IELTS apps for 2026 on both Android and iPhone, scoring them on full-length practice, Writing and Speaking feedback, free-tier honesty, and how closely they match the real exam. Here is where each one genuinely fits.

1. Band9Prep — Best All-Round App With AI Feedback

Band9Prep tops this list for one reason: it is the only app in this roundup where you can take full timed mocks and get instant AI band scores on Writing and Speaking, not just Listening and Reading answers.

Pros: full mock simulations with exam-like timing; AI feedback on Task 1, Task 2 and Speaking with criterion-level comments; works in any mobile browser on Android and iPhone; progress tracking across all four skills.

Cons: the deepest features (unlimited AI scoring) sit on a paid plan; it is a focused exam tool, not a general English-learning game — if you want cartoons and streaks, look elsewhere.

Best for: candidates who want one app covering all four skills with real feedback. Start with a full mock test guide to benchmark yourself.

2. IDP IELTS by IDP — Best Official Free Companion

IDP co-owns the IELTS test, and its official app is the safest free starting point. Expect authentic test information, sample questions, and booking tools.

Pros: completely free; trustworthy test-day information straight from a test owner; sample materials reflect the real format.

Cons: limited full-test simulation and almost no Writing or Speaking scoring — it tells you about the test more than it trains you for it.

Best for: every candidate as a free companion next to a practice app. Pair it with free practice tests.

3. IELTS Prep App by British Council — Best Free Official Lessons

The British Council's app bundles lessons, grammar exercises, vocabulary builders, and practice questions from the other co-owner of IELTS.

Pros: free lessons from an official source; solid grammar and vocabulary sections for lower-band learners; reliable exam advice.

Cons: like IDP's app, it stops short of full mock scoring — you will not get a predicted band score or essay feedback.

Best for: building foundations free before moving to scored mocks. See how to book your test when you are ready.

4. E2 (E2Language) — Best for Guided Courses on Mobile

E2 is a well-established test-prep school with a polished mobile experience, live classes, and structured pathways for IELTS Academic and General.

Pros: structured courses with teacher support options; strong Speaking and Writing method lessons; good for learners who want a classroom feel on a phone.

Cons: the full experience is a course purchase rather than a cheap app subscription — check the site for current plans; less suited to quick self-study drills.

Best for: learners who want guided classes alongside app practice.

5. Magoosh IELTS — Best Bite-Size Video Lessons

Magoosh built its name on short, clear video explanations. Its IELTS app is ideal for learners who absorb concepts better by watching than by reading.

Pros: excellent short video lessons for each question type; good study schedules; simple interface that works well on small screens.

Cons: fewer full-length mocks than dedicated mock platforms; Writing feedback is limited compared with AI-scoring tools.

Best for: visual learners and beginners who need concepts explained simply.

6. IELTS Test Pro / Practice App bypressive — Best Free Drill Volume

Several high-download drill apps (search "IELTS Test Pro" or "IELTS Practice" in your store) offer thousands of multiple-choice Listening and Reading questions offline.

Pros: huge free question banks; offline mode for commutes; good for repetitive Listening and Reading drills.

Cons: quality varies and formats do not always match the 2026 exam exactly; rarely any Writing or Speaking scoring; ads on free tiers.

Best for: extra Listening and Reading reps on the go — but verify answers against official material.

7. Elsa Speak / ELSA — Best Pronunciation Supplement

ELSA is not an IELTS app, but its AI pronunciation coaching directly helps IELTS Speaking fluency and pronunciation scores.

Pros: precise phoneme-level pronunciation feedback; fun daily drills; measurable accent-clarity progress.

Cons: does not teach IELTS Speaking structure (Part 1, 2, 3 strategy) — use it as a supplement, not your main Speaking prep.

Best for: candidates whose pronunciation caps their Speaking score.

8. Quizlet — Best Vocabulary Builder

IELTS rewards a wide lexical range, and Quizlet's flashcard sets (many user-made IELTS sets exist) make vocabulary stick with spaced repetition.

Pros: free core app; thousands of shared IELTS vocabulary sets; effective spaced-repetition modes.

Cons: user-made sets contain errors — prefer curated sets; vocabulary alone does not raise Writing or Speaking without usage practice.

Best for: daily collocation and topic-vocabulary building alongside skills practice.

9. BBC Learning English / BBC Sounds — Best Free Listening Supplement

The BBC's free apps expose you to the accents, speeds, and topics IELTS Listening loves — free, and with transcripts on many episodes.

Pros: completely free; authentic British English across topics; transcripts aid shadowing practice.

Cons: not IELTS-formatted — no question types, no scoring; you must convert listening into exam practice yourself.

Best for: free daily listening immersion. Combine with timed Listening mocks from free practice tests.

10. IELTS Word Power / Official Vocabulary Apps — Best Quick Word Drills

The British Council's vocabulary-focused apps and similar word-power tools gamify the 570 academic word families IELTS repeats.

Pros: official backing on some titles; quick daily sessions; good for bands 5.0–6.5 building lexical range.

Cons: narrow scope — words without skills practice will not move your overall band much.

Best for: five-minute daily vocabulary habits.

Verdict

If you install just two apps, make them Band9Prep for scored full mocks with Writing and Speaking feedback, plus one official free app (IDP or British Council) for authentic reference material. Use drill and vocabulary apps for spare minutes — but judge your readiness only by timed full mocks.
