What truly widens the score gap isn’t just your vocabulary, but your logical depth and response speed. If you’re part of the IELTS test-taking crowd, you’ve definitely faced these frustrations: *“I memorized templates, but my mind goes blank the second I see the examiner.”* *“As a socially anxious person, I’m too embarrassed to book a real tutor.”* *“I practiced for three months, but still froze up during Part 3.”*

With over 50 IELTS speaking apps on the market, only a handful actually help boost scores. As a reviewer specializing in AI education, I spent 2 months testing 30+ mainstream apps across 6 core metrics: question bank coverage, AI follow-up depth, correction accuracy, alignment with scoring standards, new question update speed, and cost-effectiveness. The conclusion is clear: Keraft leads by a landslide, while others barely scrape by the passing line.
