Great for leaning math.
Great app for learning math, their videoes have good details and the practice have good step-by-step help if you get stuck.
Support is good, they helped me fix the app crashing when i wrote it in a review, but i could not find a way to contact support about it on the website.
Can't give 5 stars because hard to find support and the app stops my music playing from other apps when i open it.
