Bigomatic

Bigomatic makes algorithmic complexity — the dreaded Big-O — finally make intuitive sense by letting you see it instead of just memorizing it. Every complexity class, from constant O(1) through logarithmic, linear, linearithmic, quadratic, and exponential, is drawn as a growth curve you can watch climb, so the difference between "fine at scale" and "falls apart fast" stops being abstract and becomes obvious at a glance. It's built to actually teach. A guided section explains each complexity class in plain language — what it means, what kind of code produces it, and why it matters — with real everyday examples of algorithms that land in each. An interactive comparison lets you plot several classes on the same axes and slide the input size up to see the curves dramatically diverge, driving home why an O(n²) approach that's fine for ten items is a disaster for ten thousand. You can look at common operations — searching, sorting, lookups — and see the time and space complexity behind them, and a challenge mode hands you snippets of logic and asks you to identify their Big-O, checking your answer and explaining the reasoning. Clear, visual, and focused entirely on building real intuition, Bigomatic turns a topic people usually cram and forget into something that finally clicks. Everything runs on your device: no account, no connection, no ads. Just the curves, the concepts, and complexity made clear.
