I built something that makes my life a little easier, maybe: a tiny mental math quiz: Daily Math. I want to maintain a little bit of mental math skills with minimal effort, and I heard one of the best ways is to pick two random numbers and then add, subtract, multiply, and divide them. Daily Math takes care of coming up with two random numbers and checking whether your answers are correct. The quiz is short enough that it’s easy to do it once every day despite a busy schedule. I’ve been using it for a few months now and I’ve gotten much better at it.
If you’re interested, you could add Daily Math to your phone’s home screen so that the website is like an app. I got some practice with handling animations and gestures by adding a completely unnecessary feature where the buttons can be rearranged. There are still a few small bugs in the button rearranging, and I might fix them some day, but I’m focusing on other more important things for the moment.
Daily Math was built with Expo, which uses React Native.
