• Un tout nouvel accueil : Mathix, ton astronaute, te pose quelques questions (classe, programme, chapitre en cours, ce qui te bloque), te propose de t'engager sur 7, 14 ou 30 jours, puis calcule ton point de départ. • Mathix a de nouveaux dessins : il réagit à tes réponses (bravo, trois de suite, dernière question) et il répond quand tu le touches. • Un Parcours qui répond : Mathix atterrit sur l'étoile franchie, fête la fin d'un chapitre, et l'étoile gagnée vole rejoindre ta constellation. • Réviser en prépa : la liste des chapitres par leur nom, une recherche, et une galaxie de planètes en 3D à faire tourner du doigt. L'informatique de prépa a son propre espace. • Des questions avec graphique : lis une courbe, repère un extremum, compte des solutions. • Programme de 1re tronc commun refait : six fiches par chapitre, de l'essentiel au contrôle type. • Seconde et maths complémentaires au complet. • 16 nouveaux sujets type bac en terminale spécialité, avec corrigés. • Mathix+ : l'essai gratuit de 3 jours est expliqué avant l'achat. La séance du jour reste gratuite, toujours. • Widgets refaits, sur l'écran d'accueil et sur l'écran verrouillé. • Un profil plus lisible : ton ciel de constellations et tes progrès par chapitre. • Un mini-jeu « Relier » pour associer des cartes (à activer dans les réglages). • Des corrections : calculs lourds détaillés dans les propositions, code Python bien indenté dans les sujets.
