Want to improve your math skills without having to memorize a hundred tricks? Mental Math Cards is designed to help people of all ages and skill levels improve their arithmetic abilities through easy to remember (and use) tips, practice question sets, and an addictive game. Unlike many other math apps, advanced problems are also supported to keep things challenging as your skills improve. Mental Math Cards is fully integrated with Game Center - providing both Leaderboards and Achievements. The Game Center features allow you to test your skills against the rest of the world and to share your scores and accomplishments with friends. Mental Math Cards provides step by step instructions on how to approach solving all of the problems it shows - for all operations and difficulty levels. Each difficulty level for each operation type is carefully thought out to build on the skills mastered in previous levels. For instance, hard multiplication problems are shown to be solvable by breaking problems down into medium and easy level problems. Students: Prepare for the math sections of the PSAT, SAT, ACT, GRE, GMAT, and MCAT, as well as for regular school tests. Many tests don't allow for calculators, and greater comfort with arithmetic will still improve your scores even if calculators are allowed. Professionals: Impress colleagues, family, and friends with lightning fast and accurate mental math skills. Impress interviewers during job interviews that have quantitative component by solving problems without needing a pencil and paper. Mental Math Cards supports 1 by 1, 2 by 1, 2 by 2, and 3 by 3 digit problems. Given that flexibility, Mental Math Cards is as appropriate for use by beginning students as it is for college graduates looking to sharpen their skills for quantitative interviews and to impress friends & colleagues. Mental Math Cards supports all four of the major arithmetic operations - as well as a mixed operations mode that randomly shows all types of problems. - Addition - Subtraction - Multiplication - Division Feel free to contact me with any feedback and feature suggestions. ================================== Mental Math Cards Pro Edition Subscription Mental Math Cards provides additional features using a subscription model - that includes a 3 day trial period.

About

One Stroker

Features
Read full description

One Stroker is a simple scoring app where you draw shapes in one stroke and receive a score based on beauty and accuracy. Choose from circles, triangles, squares, stars, hexagons, and hearts, then draw the shape with your finger in one smooth stroke. When you lift your finger, your drawing is scored automatically. The scoring system checks not only how similar your drawing looks, but also the features that make each shape recognizable. It evaluates straight lines, corner count, side balance, aspect ratio, star peaks and valleys, heart shape, and more. After scoring, the correct neon shape appears over your drawing so you can intuitively see where your line matched and where it shifted. Main features: ・ Draw shapes in one stroke ・ Score out of 100.0 with one decimal place ・ View shape-by-shape local records ・ Game Center leaderboards and achievements ・ Simple, modern neon-inspired design A quick, simple, and surprisingly deep one-stroke challenge. Draw a beautiful line and aim for a perfect 100.0.
