Description

Level up your math game with One By One. Featuring trigonometry and derivatives.

One By One is a math study game directed for middle and high school students who want some extra practice. Teenagers finally have a modern and refreshing app to practice even calculus, forever! That is right problems are randomly generated so you will always be getting different problems and working those brain muscles! Step your mental math game up to the next level! Additionally you can refine practice problems by choosing specific one in the "One By One Battles" menu.

FEATURES:

UNICODE/ASCII Art Style. This app was designed to mimic the "nostalgic" or retro feeling on calculators with ASCII art and simple design. The background music continues this feeling with the satisfying key clicks.

A leveling system. Go from level 1 to 99 by solving problems each step of the way! Every ten levels you unlock a brand new set of mathematical questions to help study.

ARITHMETIC. Whether you need to practice what 1+1= or what (4+3)²/(4-2)³= we got you.

ALGEBRA. As you enter into high school most students struggle with algebra, help yourself out and solve some fancy algebra equations like 3x+4=5. As you progress through the levels you can grind your way up to √(x+4)*2=6

TRIGONOMETRY. I think we can all admit that the unit circle can be tricky. Through the exp system, you can work at your own pace and master sin(0) before being overwhelmed by cot⁻¹(-1). If you are already a master of sin and cos you can blow past those problems and gain some easy in-game money! For those of you who struggle with trigonometry there's even a unit circle to help!

CALCULUS DERIVATIVES. Derivatives? That's right finally you can practice the derivative rules in any setting. The problems are perfectly tuned to be anywhere from easy mental math to slight difficult mental math. You can practice the power rule or try to figure out what the derivative of ln(2x+3) is.

LEADERBOARDS & ACHIEVEMENTS: Have a competitive personality? Well, there are now 5 new leaderboards. Each game mode has its own leaderboard and the final one is based on your balance. There is also a hidden achievement, hint you better get solving!

UPGRADES: You have a chance of encountering a "Golden Problem", solve correctly and you'll receive a math artifact that can be equipped to enhance your experience. There are 25 artifacts with 9 unique upgrades that can be used to strategize your problem-solving career!

AI BATTLES: If you are feeling competitive or want to practice a certain type of problem you can use the One By One Battles mode to get the perfect training. Additionally, you get rewarded for choosing faster AI and winning!

The perfect study tool. No matter what level of math you are this app is perfect for refining your mental math in a visually pleasing retro Unicode calculator style. You can transfer from arithmetic to calculus in seconds.

What are you waiting for? Download the app and solve math faster than your teacher!

Great app I just have one suggestion

When doing battles mode the app should automatically clear your answer if you don’t answer in time so you don’t have to spend time on the next answer deleting numbers.

Developer Response ,

Thank you for your feedback! Technically it does but what usually happens since the questions changes immediately if you were about to press a number you will press the button right after it changes. To remedy this I think we will either add a small pause between problems or not allow any entries for like .25-.5 seconds after the new problem displays.

Edit: Thank you for your feedback, I have now implemented your suggestion!

This math practice game is so fun

I love the variety of practice questions on each level, and how the next level is unlocked once you have practiced the previous level until you really know the material

Developer Response ,

Thank you! I have plans to add more options for studying, I’m glad you appreciated the leveling system!

One By One

One of the most interactive and understandable math arithmetic games I have ever played. The game is increasingly complex as one dives into the rewards system and high level mathematics, giving it an elite level of professionalism. Fun to play, helped me learn. 5 Stars.

Developer Response ,

Thank you for the review! I’m glad you enjoyed the leveling system that made studying math a bit more approachable and hopefully fun.
