Bad ad placement or fat fingers? – Komodo Abacus Math Program Review

The math problems are great. I have learned a lot while using this app on the iPad. But when I use this on the iPhone the ad banner nearly makes it impossible to proceed to the next math problem. No imagine handing this abacus to a child and see what different apps they will download or buy.
