About

Reps

Read full description

Learn to code in two minutes a day, starting from actual zero. Reps, as in repetitions: short sets, every day, until it sticks. Here the sets are HTML, CSS and Python. IT WAS NEVER ABOUT WILLPOWER Nobody has four hours. Nobody has 45 minutes. It's Tuesday, it's 10 p.m., you have two minutes and nothing left in the tank. A course that asks for more than that doesn't lose your attention. It loses your January, your March, and the idea that you might get there one day. A lesson is five to fourteen steps and two minutes. You open it, you answer, you close it. Same tomorrow. And the day after, because two minutes is something you always have. FROM ZERO. ACTUAL ZERO. Everyone writes "from scratch", then assumes you already know things. Reps starts at your very first tag, and explains every word before it asks you to type it. If the word "tag" means nothing to you, you're not behind. You're exactly where you should be. Once you've picked your path, you plan nothing and skip nothing: it's one line, and the next lesson opens when you finish the one before it. You don't count the lessons left. You count the days in a row. Everything is in English and French, interface included. YOU DON'T READ A COURSE, YOU PLAY IT Exercises that keep changing shape, all played with one thumb, never a form. You pick the right answer, you match pairs, you type the missing word, you tap the pieces back into the right order. When there's something to see, a small browser window opens under the lesson. You flip it one way, then the other, and the page changes in front of you. You don't read what HTML does. You watch it do it. Grading is instant. And when you get it wrong, nothing moves on: the question comes back before the lesson ends. That's exactly what a rep is. GENERATING CODE TAKES THREE SECONDS. UNDERSTANDING IT DOESN'T. Anyone can have a page in three seconds now. What nobody gets in three seconds is knowing why it looks like that, and what to touch when it breaks. Reps never asks you to copy. It asks you to recognize, to connect, to put things back in order. That's the part still standing when you close the app. WHAT BRINGS YOU BACK TOMORROW Your streak, and its flame. A widget on your home screen so you don't break it. 20 XP a lesson, 40 in legendary mode. Four quests a day, chests in five rarities, shards to spend in the shop: a booster that doubles your XP for 30 minutes, a shield that saves your streak the day you forget. Shards can't be bought. You earn them. Twelve weekly leagues, Bronze to Legend, against other learners. The top move up, the bottom move down. Legendary mode, for the lessons you think you've got: three lives, no help, and the node on your path turns gold. BEBOT BeBot greets you, reacts to your answers and celebrates your streak. Free, from day one to day one hundred. BeBot's chat inside lessons is part of Reps+: when you're stuck, it won't hand you the answer, it asks you the question that unsticks you. Once you've answered, it explains what just happened. Out loud, if you'd rather listen. START TONIGHT No account. No email. No card. You download it and you start, the whole first unit is open. Free: two keys a day without an account, three with one, one key per lesson, refilled at midnight. The key is spent when the lesson starts, never halfway through. Nobody stops you at question 7 to sell you something. WHO MAKES REPS Believemy, a French online school. More than 10,000 students since 2018. The lessons in Reps are written by the people who teach the courses. Two minutes a day. That's the whole commitment.
