Best math app!

JJ's mumma

This is by far the best math app for my very mathy 2 year old son. He is advanced in math for his age, but not so advanced that he is able to comprehend grade 1 math apps. This app is a prefect in-between app for the preschooler that knows their numbers and how to count but isn't quite ready to jump into arithmetic. The app also covers much more than adding and subtracting. It covers concepts such as straight lines and curved lines, positional words, subtitizing and much much more.
I know the app has had some updating issues since the last update but I have found the customer service to be exemplary. I was emailed with several solutions for the installing issue. I have never had any other app developer do that before!

Thanks for the US version!

Thanks for the update with US English. As an ex pat teaching in the US my students were more familiar with an English accent than most but it is great to have the US voice.
This app is the best thing available for my youngest students and I am hoping there is a harder version in the works. I would LOVE to have the next stage for my 6-7 year olds. This is one of the most expensive apps I own but it is worth every penny. It is a complete math program with great mini lessons and well thought out practice. There is even a quiz at the end of each topic and you can save the settings for as many different kids as you like,

Could have been great


The art, script, activities, the multiple language options, the concepts and their scaffolding are excellent. Yet, it has 2 big flaws.

* Negative Reinforcement, via a loud alarm. Young children with sound sensitivity will react very negatively at "making a mistake". The loud sound was unnecessary and may reinforce a child's fear of loud sounds with "making a mistake".

* The exercises are presented with the same scripted choices, "paint the sock green", why not a random color chosen by the program? It makes the learning and discovery boring for a child after a few tries because the examples are always the same, a simple variation in the program would have vastly improved its utility.
