I have reviewed the flash card apps in the iStore. Far and away this is the finest! No question! This is a clean and simple and refined design that allows for various settings and is simple and have just started working with a 7 year old with them. I wish that I had known sooner and looking at what was going on with the teacher's complexified handouts and watching the finger counting was driving me crazy. This is the ultimathule of flash cards... no cartoons and confusing junk. All the rest are disgusting. The boy loves it and he is not wasting time and he is enjoying learning now. Thank Masato Takagi very much! He's excellent.

Now having picked up all the other nuances, have to say that apps coming out of Japan are absolutely superior!
i41CX+ is the finest calculator in the world and Tayasui’s Sketches Pro is astounding except that the requirements are not listed.

Perfect Simple Math Flashcard App


I’m 43 and am going back to school. I realized that I had holes in my times tables memorization where I have always just done the math in my head instead of truly memorizing. It’s time to change that so I found this in my search for a flash card app. It’s simple, easy to use, and perfect for what I need it for. Not only will I soon have my 7’s, 8’s, and 9’s memorized, but all the way up to 15’s. And since this is as fun to use as most of my timekiller games like 2048 I figure I’ll have my addition, subtraction, and division “tables” up to 15 memorized soon also! Great game! Do yourself a favor and just buy the $2.99 upgrade, it’s definitely worth the money!

2 minutes and I needed to unlock everything

Best keyboard app ever!

I somehow managed to get into an advanced math class without knowing my multiplication facts. Not very well at least.. So I was in quiet a bit of a pickle, but this app really helps by allowing me to practice multiplication and division facts very easily. Not only that, but thanks to the upgrades I got I can choose specific numbers. This is by FAR my personal favorite way to practice my math facts. Plus it goes up to 15, which many apps don't do.

Don't do 1 99 cent upgrade by the way... just do the full $2.99. Thank me later
