Read full description

You choose what to remember. NOTEBARS turns it into personal recall cards and shows you when you’ve actually learned it. READ AND TOUCH Read a paragraph and tap the words you want to remember. In seconds, you get ready-made, structured notes — without typing a word. Each paragraph becomes a memory card, with keys on the left and notes on the right. During reviews, you see only the keys and recall the rest. You don’t reread — you test your memory. YOUR OWN CHOICES Two students reading the same text get different cards. The notes are built on what you picked out, not on a generic summary. QUESTIONS BORN FROM YOUR NOTES Review questions are built on the keys you created. With one tap, you can see the paragraph, sentence, or card from which each question originated. KNOW WHAT YOU DON’T KNOW You rate your memory before seeing the answer, and again after. Where the difference is large, the question is marked as critical: you thought you knew it. These are the points that will trip you up in an exam. PERFORMANCE-BASED REVIEWS Each review starts with a few questions, and your score determines when the next one comes. No progress is given away for free. TARGETED STUDY You filter what you’ll work on each time: only what you don’t remember well, only what’s important, only what’s difficult, only what you’ve bookmarked, only specific chapters. MEMORY TOOLS Color per paragraph. Memory icons next to your notes. Color inversion for what is critical. Settings for telegraphic or descriptive notes. FOR TEACHERS From iPhone or iPad, you create your own books: split text into chapters and sections, add images and videos, and color in bulk. Your students download the material ready-made. GET STARTED IN TEN SECONDS You jump straight into a training book and download ready-made books: schoolbooks for Primary, Lower Secondary, and Upper Secondary school — History, Biology, Physics, Economics, Geography — as well as personal development, philosophy, and social books. All fully editable, in Greek and English. No need to upload anything.

STUDY SMART • Επανάληψη με χρονικά διαστήματα, ώστε η εφαρμογή να σου θυμίζει ακριβώς ποιες ασκήσεις να ξαναδείς και πότε. • Quick Test και Daily Challenge για γρήγορη, καθημερινή εξάσκηση. • Διαγωνίσματα ανά κεφάλαιο για να μετράς την πρόοδό σου κάτω από συνθήκες εξέτασης. TRACK YOUR PROGRESS • Ποσοστό κατάκτησης, ευστοχία πρώτης προσπάθειας και σερί ημερών μελέτης. • Χάρτης δραστηριότητας και σύστημα βαθμίδων μαθηματικών, από τον Πυθαγόρα ως τον Gödel. • Λειτουργεί 100% offline, χωρίς διαφημίσεις και χωρίς συλλογή προσωπικών δεδομένων. Το Pygon είναι ανεξάρτητο βοήθημα μελέτης και δεν σχετίζεται με το Υπουργείο Παιδείας ή κάποια εξεταστική αρχή. Το περιεχόμενο ελέγχεται με προσοχή αλλά μπορεί να περιέχει λάθη, γι' αυτό πάντα να το διασταυρώνεις με τα επίσημα βιβλία και τους καθηγητές σου.
