Even a simple thing like figuring out the tip at a restaurant takes some effort. This app makes it all less daunting and I can see how mental calculations get easier with practice! And, it's actually fun!!! (I know the developer and he's known for his sharp mind as well as for his meticulousness. And it shows in this interface) ### 5/5 — Great app for mental math *2026-02-07* Great app! I don’t work in finance, but I found this app to be addictive and a fun way to get more comfortable with mental math.
