App Replicator

Works out how one feature of an app you own behaves, writes a spec with tests, and helps you rebuild it clean-room on a free or low-cost stack.

What it does

App Replicator helps you stop paying for an app when you only use one feature. It confirms you own or may analyze the software, studies the feature with static analysis first, tags each finding as confirmed, inference, or unknown, and gives an honest verdict on whether a rebuild is worth it. It writes its own SPEC.md with pass/fail tests and, if you ask, builds and validates a clean-room version without copying code or assets.

How it works

Name the target app, the feature you use, and optionally your preferred stack.
It confirms you own the software or have permission, then checks its tools and can connect REA for deeper analysis.
It maps and traces the feature, tags each finding, and rates how realistic a free rebuild is.
It writes SPEC.md with behavior, edge cases, and 5 to 10 pass/fail tests.
If you ask, it builds the smallest version that passes, compares it with the original, and helps you package it.
