### 1/5 — Nul! Ne perdez pas votre argent

*2025-11-26*

Je l’utilise sur Iphone et rien n’est réactif. Les boules ne se déplacent pas facilement donc aucun intérêt pour faire comprendre à l’enfant comment compter les unités. Idem pour les autres le tableau noir est juste une illustration il n’y a rien de pédagogique. Quelle déception ! Comment se fait-on rembourser ?

### 5/5 — Excellent

*2020-04-15*

I had some difficulty at the beginning but now it works well. Maybe they fixed it or maybe I was doing it wrong. I would suggest the developer do an explainer video so parents can understand how to present it.

**Developer response:** we’re sorry to hear this. Please contact us on support@dsokiacademy.com and ask for Valerie.

### 1/5 — Ne marche pas sur IPad

*2020-03-08*

Application démarre mais bloque sur Ipad

**Developer response:** Bonjour, ce n’est pas normal. Écrivez nous à Support@edokiacademy.com et demandez Valerie

### 5/5 — Super !!!

*2016-01-21*

Achetées il y a peu afin d'aider ma cadette dans l'apprentissage de la multiplication, mes deux enfants de 6 et 8 ans se sont emparés immédiatement de ces 3 applis et y jouent avec plaisir et assiduité. (D'autant plus que le temps passé sur écran est assez restreint chez nous) Ils passent désormais leurs 20 minutes quotidiennes autorisées à faire des maths avec plaisir !!! Il est trop tôt encore pour évaluer leurs progrès du point de vue scolaire mais je ne manquerai pas de poster un avis dès que je serai fixée sur ce point.

### 5/5 — Complet

Hyper complet avec le matériel montessori pour apprendre progressivement a faire des additions complexes.

*2015-08-29*

Установил на ipad, пишет что это тестовая версия и она не для продажи - а мне ее продали за 250 руб. Но это ладно, потом она просто не работает - выдает пустой экран и висит. Жесть какая

### 5/5 — toll
