EF Hello: Language Learning
by Signum International AG
EF Hello is a conversation-focused English learning app built around an AI tutor named Addi, developed by Signum International AG and available free since 2018. At 114 MB it stays reasonably light, and its short session design means you can genuinely fit practice into a lunch break. With nearly 9,000 ratings averaging 4.84, user satisfaction is hard to argue with, though that number reflects a self-selected audience already committed to the app.
The Addi Experience
The core selling point is Addi, an AI tutor that reacts to your pronunciation, grammar, and fluency in real time. For learners who freeze up speaking to humans, having a patient, non-judgmental AI listener is a genuine advantage. The feedback loop feels immediate rather than delayed, which keeps short sessions from feeling hollow. Whether the corrections are nuanced enough for advanced speakers is a fair question, but for beginner-to-intermediate users the responsive coaching is a real differentiator.
Who Gets the Most From It
EF Hello is clearly built for adult learners with fragmented schedules, not students who can block out an hour. The five-minute session structure works if your goal is conversational confidence, not grammar certification. Learners preparing for a job interview or casual social situations in English will find the goal-oriented paths useful. Those chasing formal proficiency scores or broad multi-language support will hit a ceiling quickly, since the app focuses specifically on English.
Practical Friction Points
The app is free to download but carries in-app purchases, and the store listing does not specify what is gated behind payment. That ambiguity is worth flagging before you invest time building a habit. At version 9.1.2 with a June 2026 update, development appears active, which is a positive sign for long-term reliability. Still, any app that ties progress to a subscription model can feel limiting once the free tier runs dry.

Cons
