Clairement la meilleure application de N-Back de tout l'App Store.

Là où les autres applications sont austères et limitées, celle-ci est ultra soignée, jolie et colorée. Niveau contenu, c'est énorme : Dual, Triple, Quad et même jusqu'à Hepta N-Back, sans compter les mini-jeux et les tonnes d'options de personnalisation.

Un immense respect au développeur qui est super sympa et qui a laissé l'application 100% gratuite pendant des mois avant d'ajouter une option payante très abordable. Ça change des abonnements abusifs. Un travail exceptionnel, 5 étoiles amplement méritées !

Response from developer

Un immense merci Gabriel pour ce retour ! Savoir que le design, la variété des modes, du Dual jusqu'à l'Hepta N-Back, et le Laboratoire vous plaisent autant est la plus belle des récompenses. Bonnes séances, et merci pour votre confiance !

Meilleur appli pour travailler la mémoire

C’est l’application que je cherchais ! Enfin une vraie interface pour du dual n back et en plus de ça l’appli est truffée d’excellents jeux pour développer les capacités cognitives. Avec les stats on voit bien notre progression et le leaderboard permet un peu de compétition pour ceux qui souhaitent. On voit que c’est développé avec amour, merci pour cette pépite 🙌

Response from developer

Un immense merci, votre message me va droit au cœur ! « Développé avec amour », c'est exactement ça : je construis l'application seul, et chaque jeu du Laboratoire, chaque statistique et le classement ont été pensés pour que la progression se voie vraiment. Merci d'avoir pris le temps de le dire ici, ça compte énormément pour une petite application indépendante. Excellent entraînement à vous, et si une idée vous vient pour aller plus loin, écrivez-moi : Gambinoromeo9@gmail.com. Roméo - Développeur de Dual N-Back

Sell out.

Before this month your could train as much as you wanted, now it has a dumb pay wall if you want to play for more than 5 minutes.
Before this was the best dual n back app, it was free and interface is great but I guess the developers weren't happy with being what people needed & decided to add a pay wall. They sold out & now I gotta find a new app if I want to play my full 10 minutes a day. Shame

Response from developer

Hi Brain-kun. My earlier reply here was wrong, and I am sorry for it: the daily limit on n-back training has not been removed. Free play is three Dual N-Back sessions a day, up to N=2; unlimited sessions and higher levels are part of Pro. What did change since your review: every Cognitive Lab game is free and unlimited again for everyone, and every offer screen has a close button. I would rather tell you exactly where the line is than have you reinstall and hit it. Support: https://romeoapps.app/en/dual-n-back/support/

Super

Superbe appli, après en avoir profité lorsque elle était gratuite je comprends qu’elle soit devenue payante. Aucune appli même payante était aussi bien que celle ci, et j’apprécie le fait que les anciens utilisateurs payent seulement 6e pour l’année. Je continuerai à l’utiliser encore longtemps, et merci de continuer à l’améliorer comme vous faites.
Serait il possible néanmoins de supprimer le « majuscule » après la lettre, c’est très perturbant.

Response from developer

Merci beaucoup Gussp pour vos 5 étoiles et votre soutien ! Le « majuscule » prononcé après chaque lettre est corrigé depuis la version 3.7.5 : les lettres sont maintenant lues seules, sans mot ajouté. Si vous l'entendez encore après la mise à jour, écrivez-nous : https://romeoapps.app/fr/dual-n-back/support/ Bon entraînement !

Best N-back

Was a great free App, now requires mandatory subscription..

Response from developer

Hi Green Gt4.6, thank you for the review, and a correction to my earlier reply. No subscription is required to open or use the app, but free training has limits: the Dual N-Back mode, three sessions a day, up to N=2. The other n-back modes, higher levels and unlimited sessions are part of Pro. All the Cognitive Lab games are free and unlimited for everyone. Support: https://romeoapps.app/en/dual-n-back/support/
