About Simplang

Learning a language is mostly a numbers game you never quite get to see. How many hours does reaching B2 actually take, and how long is that at an hour a day? When should you review a word so you don’t forget it? How many new words a day hits your target by the exam? Are you really at an intermediate level, or does your speaking lag your reading? How much listening have you done this month, and is the daily habit holding? None of these are hard once you can see the figures — but carrying them in your head, session after session, is exactly where motivation quietly leaks away.

Simplang is built around that gap. Rather than long essays you have to wade through, the site is a set of small, single-purpose calculators, each aimed at one real decision a learner faces. The Hours-to-Fluency Estimator maps the CEFR levels onto representative study hours and divides what remains by your daily pace. The Spaced-Repetition Review Scheduler projects the SM-2 review dates behind Anki, so you revise just before you would forget. The Vocabulary Goal Calculator turns a target and a deadline into a words-per-day pace, adjusted for how much you actually retain. The CEFR Self-Assessment Scorer asks you to rate the four skills and reports your overall level as the weakest of them. The Immersion Hours Tracker adds up the listening, reading, and watching that quietly fuels fluency. And the Study-Streak Consistency Calculator makes the daily habit visible, because consistency beats cramming.

Alongside the calculators, the blog and learnsection explain the ideas the tools rest on — how second-language acquisition works, what comprehensible input and spaced repetition really do, how the CEFR levels are defined, and how vocabulary, grammar, and pronunciation fit together — and the Museum of Languageis a browsable collection of the world’s languages, writing systems, linguists, and polyglots, with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. Simplang is independent and not affiliated with any language school, exam board, app, or publisher. It is supported by advertising, which is how the tools stay free with no account required. Every figure a tool produces — an hours estimate, a review schedule, a daily word count, a CEFR level, an immersion total, a streak — is a general estimate based on the numbers you enter and on widely used frameworks and study methods, not a placement result, an exam score, or professional advice. CEFR hour guidelines and retention vary from learner to learner, and the tools deliberately ask you to supply your own figures rather than pretending one path fits everyone. For an official level, sit a recognised examination. If a tool looks wrong, or there is a calculator you wish existed, the contact page is the place to tell us.
