It was very detailed. I appreciate that, unlike some apps or websites that give math shortcuts, it not only gives the trick, it explains the reasoning behind it, and gives many exercises afterwards to ensure that you understand. The math tricks are effective and save a lot of time that would otherwise be spent writing out the entire problem and using the traditional way. My only concern is that there are a little too many ads. Ads put aside, it is a very high quality app that I would recommend to those having trouble with math, those studying for a timed test, or simply those who want to save tons of time on math.

Great app, useful for so many reasons, but for the timers! Argh! I couldn't figure out how to turn them off (I'm not even certain you are able to...?) and they added needless stress. There are other apps that are comparable (withOUT the short timer) though not as comprehensive, so if you're also stressed by timers, go elsewhere. App developers, is it possible to take the timerrs off? Am I missing something?

Why it now says "unable to start activity ComponentInfo..." when I open the app? I also see some other users have the same experience. Would be nice if there are some updates or fixing. Thanks Very good exercise for mathemaniacs 😄, especially those who want to learn more about counting and numbers. There are various beginner to pre-advanced exercises and practices, enough to hard-wire the brain 😃😃 Don't forget to visit the Dev's IG for more challenging math-tricks and problems. Thanks Dev!
