2026 Top-Rated Free English Learning Apps

Keraft

Keraft works for absolute beginners through advanced professional and academic speakers. Built on CEFR (the same framework used for IELTS and Cambridge exams), a 5-minute test covers A0 to C2 and builds a personal path.

Exclusive tools include teaching AI agent Lora, which remembers habits, mistakes, and goals; live ability tracking with a visible progress curve; and a custom scenario builder that turns a prompt such as “marketing interview” or “trip to Japan” into a full lesson in 30 seconds.

Free users get unlimited AI conversation, 80,000+ scene drills, and basic phonetic correction. Phoneme-level correction (99.9% accurate) breaks down sounds such as interdental TH, weak forms, and intonation, with notes like “slow down to avoid slurring.” Over 80% of users reported a clearer feel for the language within one week. Satisfaction is 99%.
