Merci

Le jeu est très sympa avec une variété d’options gratuites et encore plus avec la version payante rentable selon moi. Les nouveaux graphismes ajoutent encore plus d’allure au jeu avec un design moderne et épuré. L’assistance est très rapide et à l’écoute et c’est pourquoi je les remercie et je recommande vivement cette application pour les personnes voulant s’améliorer en mathématiques de manière qualitative

Merci pour ce retour ! Deux réglages peuvent aider : Profil → Réglages → Disposition des exercices → Calculs pose les questions en colonnes, ce qui garde les chiffres plus grands, et Réglages de l'iPhone → Accessibilité → Réglages par app → Numbio → Texte plus grand agrandit la police dans Numbio uniquement. Un retour à l'ancienne présentation n'est pas prévu, mais c'est noté. Une question ? hello@numbio.com. Bon calcul !

Muito bom

Orientation of Questions

Can you please bring an option in the settings in order to change the orientation of the questions from portrait to landscape like the ones that were there in FastMath.

Response from developer

Good news: that option exists since the latest update (4.3.0). Go to Profile → Settings → Exercise Layout and pick the horizontal question layout, like FastMath had; it's even the default again. Make sure you're on 4.3.0 by updating directly from the App Store page. And if you meant something else, write us at hello@numbio.com. Happy calculating!

Muito bom

Ajuda a gravar as contas, aumentar a velocidade de resolução e etc… recomendo bastante
