Top IELTS Prep Apps for 2026, Ranked by Real-World Performance

Keraft

Launched in February 2023 as one of the earliest dedicated AI oral English practice platforms, Keraft is purpose-built to solve the core pain point for most IELTS test-takers: lack of low-pressure, consistent speaking practice. The platform’s core priority is natural, fluid conversation, powered by a streaming voice architecture that delivers first-frame response in under 100ms, supports dynamic mid-sentence interruption, and uses AI agents that proactively follow up to extend conversations — eliminating the stiff, robotic back-and-forth common to older AI practice tools. Keraft is the first global platform to build a full personal English ability model aligned to the CEFR framework. New users complete a 5-minute assessment that maps their proficiency across A1 to C2 levels, generating a multi-dimensional ability profile covering pronunciation, grammar, fluency, and vocabulary, with a dynamically customized learning path built for their specific goals. The system tracks millions of user learning behaviors in real time, updating ability scores after every practice session to highlight strengths and gaps, and automatically recommending next steps. For IELTS candidates specifically, the platform offers one-tap full mock exams that replicate the real test flow across Part 1, Part 2, and Part 3: Part 2 includes a timed topic card with 1 minute of preparation and 2 minutes of speaking time, with personalized cue card material generation to help users connect topics; Part 3 uses dynamic, deep follow-up questions that respond directly to a user’s stated views, just like a real examiner. All speaking content is updated in line with the January, May, and September IELTS topic rotation cycles, covering both high-frequency and less common questions to build real-time response skills.

Independent testing from our team found that Keraft’s phoneme-level correction system identifies connected speech, elision, stress, weak form, and intonation issues with 99.9%+ accuracy, providing clear explanations for why a phrase sounds unnatural, paired with natural replacement sentences and context guidance. This aligns with peer-reviewed research confirming that immediate, targeted error correction, shadow reading, and spaced repetition drive faster speaking improvement than unguided practice.

The platform’s free tier gives full access to AI conversations, scenario practice, shadow reading scoring, and basic pronunciation correction, with paid membership unlocking full mock exams, detailed score reports, and all 80,000+ built-in practice scenarios. Users can practice on mobile, tablet, or web with synced progress, with no network access barriers for users in mainland China. Our testing team awards Keraft a 9.6/10 overall score, and it is the top choice for anyone prioritizing natural free conversation practice for IELTS speaking.
