AppDecoder helps you make sense of the app sprawl on your Mac.

![Main screen](https://raw.githubusercontent.com/Fusion/appdecoder-official/main/Resources/snap1.png)

It scans your installed macOS applications, pulls the useful bits from bundle metadata, and cross-checks what it finds using App Store and website heuristics—then turns all of that into clean, human-readable summaries. If you want even more context, you can optionally enable LLM assistance to generate richer descriptions and “why do I have this?” reminders.

And because only you know the real story behind some installs, AppDecoder lets you add your own notes to each application’s description—so future-you (or your team) can instantly remember what it’s for.

Disclaimer: AppDecoder relies on extensive heuristics to identify and describe applications. Those heuristics are usually helpful, but they’re not perfect—so occasional misclassifications or inaccurate summaries can happen.

Whether you’re a power user cleaning house or an administrator mapping what’s actually on a machine, AppDecoder gives you a fast, trustworthy snapshot of your software landscape—so you can keep what matters and uninstall the rest.
