Real life training

I was so impressed with this app that I purchased it. I love practicing using the abacus and this app really delivers excellent training. They explained the friends concept with small and large compliments and cover addition, subtraction, multiplication, and division. Correct finger movements are taught as well and it teaches you how to transition from a physical abacus to using mental math - calculating all the math in your head. This is something that should be taught from a young age. Just like reading, math can be learned as soon as they start speaking and earlier. I have no complaints.

Just what I was looking for!

This has been a great tool already with just a couple of days. I’m using this for foundational learning as well as practice but I don’t always have my soroban with me. I do think there are some typos that make it sometimes a hair confusing (top/upper number) I’m pretty sure means leftmost number. I’d love to help clean up some typos if you guys are interested! It would be an awesome way for me to learn as well since I’d probably be reading most of the copy used in this app. Anyways thanks for the app and I’ll continue learning! Looking forward to mastering this skill and improving my brain game! Apparently I never hit send but I have some additions anyway! Still love this app but when I’m practicing, the layout has a black bar that grows with the soroban. I’d rather that black bar be on top because I keep pulling the Notification Center down instead of pulling down the 5 bead. Please remove the black bar or move it up too where it will actually be more of a feature than a hinderance lol.

I Added Two Stars

The original app only worked in portrait mode, so I gave it three stars. This new version works in landscape, which makes more sense for an abacus. Also, they added instructions on finger technique. Speeding up the finger work helps you to avoid overthinking, and recognize the patterns rather than trying to do the math in your head and make the beads agree. I’ve found that the quicker I work the beads, the better I do on the tests. Great app! I just upgraded to the paid version ($5.99). Well worth it! (Now I just need to find a real abacus.)
