## What is Ocelle?

Train for aptitude tests, then learn to spot the traps of your own brain.

APTITUDE TESTS
Nine kinds of exercises, in the spirit of selection tests: number series, letter series, dominoes, matrices, mental math, attention, memory, mental rotation and logic.
• The daily test: 10 questions, the same for everyone, free. Every answer is corrected and explained right away.
• Training: 10 questions in the aptitude of your choice, from easy to hard. One free session a day.
• The mock exam: 30 questions in 20 minutes. Corrections come at the end, with your results by aptitude.
• "Understand my mistakes": go back over every missed question with its explanation.
The questions are created on your iPhone.

ONE MENTAL TRAP A DAY
• Today's trap: a cognitive bias, a fallacy or a number trap, explained in three minutes, with a real-life scene and a practical antidote.
• The daily challenge: five everyday scenes, two minutes. Can you spot the trap? Same challenge for everyone, so you can share your score.
• Every trap shows how solid the science is (solid, nuanced, debated, or a reasoning error) and comes with an optical illusion drawn for the app.
• Your streak, your level of lucidity, a calendar of your last five weeks and your accuracy by aptitude.

HONEST ABOUT WHAT IT IS
Ocelle is a training tool. It is not an official test, it does not measure your IQ and it does not predict whether you will pass an exam.

PRIVATE BY DESIGN
No account. No ads. No tracking. Your progress stays on your iPhone.
