There are two modes: Infinite Mode, where you can solve problems at your own pace 10-Question Time Attack, where you can enjoy the thrill of speed and accuracy You can also choose the difficulty level, making it easy to start with the basics and gradually level up. Answers are entered intuitively using a number pad—just tap the input field and type. Correct answers trigger light, pleasant feedback, letting you move quickly to the next question. Rather than detailed explanations, the app prioritizes a “feels good to use” experience. Your performance—such as correct answers, streaks, and time—is recorded and can be reviewed on the Stats screen. The design encourages relaxed, pressure-free practice that’s easy to keep up with. Math doesn’t have to be scary—yet it can still be real math. With that spirit, dive in and start solving problems, endlessly.

Constant Challenge's advantage is ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price and device support there is nothing between them.
