Formula Motion is an animated math learning app for iPhone and iPad. It turns abstract formulas, geometry theorems, and number patterns into clear visual animations. Instead of simply memorizing formulas, learners can watch how each idea is built through movement, color, diagrams, and step-by-step explanations. Formula Motion helps students understand topics such as addition on the number line, circles and π, area formulas, the sum of triangle angles, the Fibonacci sequence, and the Mandelbrot set. Each lesson includes a visual animation page, formula explanation, diagram-based reasoning, and key takeaways to make mathematical thinking easier to see and understand. On iPhone, Formula Motion is great for quick learning anytime. On iPad, it offers a larger visual space for classroom teaching, parent-child learning, and deeper exploration.

The nagging stops when the deal is written down. Your child sees what they owe, marks it done, and waits for you to approve. Nothing counts until you say it does, and every credit that moves has a reason written next to it. No more arguing about what was agreed. HOW IT WORKS • You set the tasks: chores, homework, reading, habits • Your child marks them done • You approve, and the credits land • They spend credits on rewards you agreed on together FOR PARENTS • Create a task in seconds, or pick from over 100 templates sorted by age • Set the days a chore repeats, and a time it has to be done by • See when each one was last done, and how often it was missed • Give each child a goal: one thing to work on for three or six months, from 21 ready-made goals or your own • See active days week by week, and compare the last four weeks with the four before • Mark work done yourself, for the days your child is nowhere near a device • Approve work, or send it back with a reason, from one queue • Give a bonus or take credits off, and your child always sees why • A full ledger. Every change is recorded and nothing quietly disappears • Parent Lock. Face ID, Touch ID or a PIN guards leaving Kid Mode, CSV export, deleting the household and changing the PIN FOR KIDS • Their own side of the app: today's tasks, their balance, the reward shop • Streaks, levels and 44 badges that take months to finish, not minutes • A chore not done by its time is gone, and they see what it was worth • On their own device through iCloud, or on yours in Kid Mode LEARNING BUILT IN • Four subjects: math, physics, chemistry and biology, tuned to their age • Pick one topic, so the night before a test is spent on that alone • Print the sheet, or the answer key, then type in the score from the paper and the credits follow • Math word problems for 13 topics, every answer exact, and you read every set before they do WHAT IT COSTS • No ads. No tracking. No account • Your data stays in your family's iCloud, not on our servers • Reward Study Pro is a subscription: the yearly plan starts with 14 days free, and there are monthly and weekly plans with no trial. Cancel any time • Or pay once: the lifetime plan keeps Pro for good, with Reward Ideas included • Pro is what runs the app: as many children as you need, tasks your children can mark done, rewards they can spend on, themed word problems and CSV export. Shared through Apple Family Sharing • If a plan ends, nothing is deleted. Your tasks, rewards, credits and history stay readable, and you can still award and deduct credits by hand • Separated parents can each run their own household. Two households come with Pro Terms of Use: https://reward.study/terms Privacy Policy: https://reward.study/privacy
