About this app

Quick Digit Math is a mental arithmetic trainer built for anyone who wants to sharpen their calculation speed without picking up a pencil.
Each session presents a sequence of arithmetic problems — addition, subtraction, multiplication, and division — at a pace you control. You enter answers directly through a built-in numpad, which keeps your hands in one place and your focus on the numbers.
The app tracks your performance over time: correct answers, average response time, streaks, and session history are all stored locally on your device. No account required, no data sent anywhere.
You can adjust difficulty to match your current skill level, choosing from basic single-digit operations up to multi-digit challenges. Session length is configurable, so a two-minute warmup and a fifteen-minute deep drill both fit naturally into the flow.
Progress history is presented as a simple chart so you can see whether your speed and accuracy are improving week over week. All data lives on the device and stays there.
