I have an iPhone 7 and the app says “sorry, your device is too small” when I try to open it.

When I looked on Amazon and the App Store for an abacus, I kept finding them with 10, not 9, balls in a row and different rows had different colors. I would love it if you added a 10 ball to each row and let me choose the color of each row. An in-app purchase of these options works for me. I really like the size of the balls. The design is very professional looking. The abacus is for me, not a child. I need it for physical therapy. For example, my therapist wants three sets of ten with a ten second hold each time. I am 75 and lose track of all those numbers. I will use each pair of rows for the three different categories.
