About this app
Polyacounters is an iOS tool designed for learning combinatorics and counting theory, helping you understand the classic problem of "how many fundamentally different coloring schemes exist" under the influence of symmetry groups. In Workbench, you can set the number of vertices n and available colors k for a regular n-sided shape, and select the type of group action - identity group, cyclic group C ₙ, or dihedral group D. The application automatically calculates the number of orbits (equivalent classes) based on Burnside lemma, displays the fixed point contribution of each group element, and provides the complete counting result through P ó lya enumeration theorem and cycle index. When the parameters are appropriate, the application will enumerate all equivalent classes and display the representative coloring of each class in a colored polygon graph, intuitively demonstrating how symmet…
App details
What you can learn from Polyacounters
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 3 screenshots above are Polyacounters's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Polyacounters runs a light set with one background colour (#FCF4FC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #9C6CAC, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
