Купила программу, а на *2020-11-08* планшет с этим же Личным кабинетном прост купить заново ### 3/5 — Frozen *2020-10-13, version 1.4.3* The app is stuck on the home page and won’t open. Quite disappointing for my son who is needing to do schooling at home while in isolation. ### 1/5 — App no longer works *2020-10-10, version 1.4.3* This app stopped working a few months ago and is no longer usable. It doesn't even open. ### 2/5 — Problème depuis la dernière MÀJ *2020-10-09* Bonjour, depuis la dernière mise à jour l’appli ne démarre plus! Je souhaite le remboursement **Developer response:** Bonjour, nous sommes désolés la dernière version iOs a provoqué un bug dans l'app. Pouvez-vous nous écrire à support@edokiacademy.com ?. ### 1/5 — Vide *2020-10-08* Ne fonctionne pas. Le logo apparaît puis plus rien. Merci de faire le nécessaire **Developer response:** Bonjour, Pouvez-vous nous contacter à support@edokiacademy.com ? Un bug provoqué par la nouvelle version iOs s'est introduit dans l'app. ### 1/5 — Stuck *2020-10-01, version 1.4.3* It is stuck on the logo screen, no content ### 5/5 — Excellent app for learning early math concepts *2017-01-11, version 1.4.3* My 4 1/2 yo loves this app! She is motivated and feels accomplished when she solves a question and gets points to acquire more monster parts. Admittedly, her favorite thing to do is blow them up, but in the interim she has mastered simple addition and is now learning simple subtraction, simple division (halves, quarters, etc) and is curious about even and odd numbers. This app has supported her learning with me - mostly because the app is as tireless as she is and there are only so many times I can set up objects for her to calculate before I reach my limit. I like that I can customize her learning so that it's appropriate to her level - she's not yet ready for double digits. She was getting frustrated using big sister's profile so I made a new one for her where she has built her confidence and looks forward to her time on the iPad so she can play her monster math game. All in all, I have no complaints - rare indeed for an expensive app. It's stable and responsive on our iPad 2 and my iPhone 6P. The music/audio is pleasant and not annoying. Love love love! ### 1/5 — 구매취소합니다 *2016-05-23* 뭘 눌러도 인식이 안되고 계산만 나오네요 **Developer response:** 지원팀 support@edokiacademy.com 으로 문의하여, Valerie와 상담하십시오. ### 2/5 — Les enfants n'accrochent pas... *2016-05-15* Bien pour les parents et sur le papier (méthode montessori) Mais mes enfants n'accrochent pas du tout... 6 et 8 ans! Pas de véritable jeu - elles ne s'amusent pas donc ne l'utilisent pas! ### 5/5 — must have app... *2016-04-20, version 1.4.3* Excellent math app for kids. Fun and easy to play. I love the lab where you can experiment the monsters! ## Frequently asked questions about Montessori 1st Operations ### What age range is Montessori 1st Operations designed for?
