App is buggy – Newton - Multiplication Review

I really like the design and flow of the app. But HUGE PROBLEM, it can be buggy in very annoying ways. Sometimes when I spam the answer too quickly, it will mark me wrong. When the motivating popups appear, sometimes the math problem changes as I’m typing and causes me to get it wrong. When the timer runs out, the game keeps running for about half a second, making me think I entered the answer in time, when I did not. These issues make the app annoying to use. If they are fixed, then I would highly recommend it to anyone who wants to practice multiplication.
