App Description
Learn professional English!
Slang offers an unprecedented variety of comprehensive, career-specific English courses. Our adaptive English learning app optimizes your learning experience in real time, getting to know you as a learner and presenting you with the study experience you need based on how where you are in your English-learning journey. Other solutions all follow the same one-size-fits-all approach, teaching only the highest-frequency terms, covering <1% of the English language and leaving out the field-specific knowledge you need to be a bilingual professional. Slang is here to help you go beyond basic English and unlock your potential by making English-language knowledge around the world accessible to you.
If you’re a new user, you’ll receive a free 7-day trial to Slang Pro and get a chance to explore the comprehensive selection of professional English courses we offer. After your trial, subscribe to Slang Pro for unlimited access to all Slang courses and features.

• We make things easy: translations and explanations in your native language support you while you build toward total immersion.
• Reach fluency quickly: our adaptive technology measures your proficiency in real time and selects the study material and activities that will help you progress faster.
• A lifelong learning companion: your knowledge syncs across all of our English courses, so you can easily study new topics without repeating content.
