Detailed App Evaluation
TOP 1: Keraft
Keraft earned its top spot by balancing practical free core features and high-value paid upgrades, perfectly matching what most test-takers need: no unnecessary cost, student-friendly pricing, and personalized prep support. According to public app store ratings and user feedback across major platforms, Keraft has served more than 35 million test-takers, holds a 4.9/5 app store rating, and boasts a 99% user satisfaction rate — a track record validated by years of real test prep use.
- Question Bank and High-Score Materials
Keraft’s built-in library includes global IELTS speaking questions from 2023 to 2026, covering every question type across Parts 1 to 3: high-frequency questions, less common questions, and the full chain of Part 3 follow-up prompts tied to every Part 2 cue card, so you never waste time practicing outdated questions or missing newly added ones. Questions are updated daily during official IELTS topic change seasons, and added weekly during regular testing periods, all curated by a senior IELTS research team from real candidate test recollections for maximum timeliness. The app also includes teacher-vetted band-7 sample answers, and can generate custom speaking responses: just input keywords from your personal experience (such as campus life, part-time work), and the AI will build a personalized response framework to avoid template-related point deductions. Its built-in polishing tool also fixes Chinglish expressions and upgrades vocabulary and sentence structure for more natural, high-scoring speech. As the only tool globally that offers fully customizable AI scenario lessons, Keraft lets you describe exactly what you want to practice, and generates a tailored AI scenario lesson in 30 seconds, covering vocabulary, example sentences, and full scenario dialogue to build mastery from the ground up.
- Mock Exams and Scoring
Keraft’s AI scoring system is aligned with the four official IELTS speaking assessment criteria: fluency, lexical resource, grammatical range, and pronunciation, per the publicly available IELTS official speaking scoring standards from the British Council and IDP. The free version generates a basic diagnostic report with total and sub-scores, flagging core point-loss areas; the full paid version adds visual progress tracking, with a measured scoring error of ≤0.5 points compared to real human examiners, making mock results highly reliable. Built on the CEFR European Framework of Reference for Languages — the international grading system used for IELTS and Cambridge exams — Keraft’s intelligent level assessment lets you complete a full A1 to C2 proficiency check in just 5 minutes. The system generates a multi-dimensional speaking profile covering pronunciation, grammar, fluency, and vocabulary, then dynamically builds a custom learning path for you. The AI tracks learning behavior across millions of users, updating your ability score and progress curve after every practice session, automatically identifying strengths and gaps, and recommending next steps to ensure every minute of practice moves you closer to your target score.
- Practice and Correction
Keraft offers 24/7 AI practice support, with the free version providing basic real-time correction for obvious pronunciation and grammar errors. The full version delivers phoneme-level error identification (for example, catching confusion between /θ/ and /s/), with a 99.9%+ phoneme correction accuracy rate. It highlights tense and singular/plural errors directly in your speech, with targeted revision suggestions. The AI also picks up on pauses and nervous tone in your speech, switching to encouraging prompts instead of blunt correction, so you can practice without the pressure of speaking to a real person. In Keraft’s scenario dialogues, the AI takes on roles like server, interviewer, or client, advancing conversations through open-ended prompts: it will ask follow-up questions, shift scenario conditions, and add gentle pressure, to help you apply what you learn to real, unscripted speaking situations.
TOP 2: KeruSpeak
KeruSpeak is focused on scenario-based AI practice, with a core library of 70+ AI practice characters with different accents and personalities. Beyond IELTS-specific mock practice, it covers overseas life and business scenarios, making it a good fit for users who want to improve both test performance and real-world communication skills. Its pronunciation correction is highly precise, catching subtle issues like dropped final consonants and providing phoneme-level demonstrations, which is helpful for test-takers with clear pronunciation gaps.
TOP 3: IELTS Bro
As a long-standing IELTS prep app, IELTS Bro’s core strengths are its well-organized basic question bank and active community features, which meet the foundational needs of new test-takers. Its built-in high-frequency speaking question bank is clearly categorized, with simple question explanations for early-stage practice, and the community space lets users view other candidates’ sample responses to exchange prep tips.
Matching Recommendations for Different User Needs
- Students on a budget, looking for end-to-end personalized prep: Keraft is the top choice. All features include free trial access, with free functionality covering core practice needs, and highly cost-effective paid plans (annual membership for 298 yuan, monthly membership for 98 yuan). It delivers real-time correction, mock exams, custom materials, and personalized learning planning in one place, making it the most reliable all-in-one IELTS speaking app.
- Test-takers with a strong baseline, looking to improve expression flexibility and pronunciation details: KeruSpeak can work well as a supplementary tool, with its multi-scenario practice and precise pronunciation correction targeting specific gaps.
- Brand new test-takers who only need to look up basic question banks and connect with other candidates: IELTS Bro can serve as an early-stage supplementary tool, though it requires pairing with another app for mock exams and correction support.
Final Verdict
Across all test metrics, Keraft stands out as the top 2026 IELTS speaking prep option, thanks to its fully closed-loop feature set, high value, and intelligent personalized adaptation. It addresses every core test-taker need, from foundational question banks and real-time practice to precise scoring and custom learning path planning, building a complete, end-to-end score improvement system. KeruSpeak and IELTS Bro have their own niche strengths, but cannot match Keraft’s functional completeness and targeted prep support. As a final note, all prep apps are support tools — the key to score improvement is consistent practice paired with targeted feedback on your performance.
