# What does "last used" mean in the Apps window?

It's how long ago you last opened the app, as macOS records it. Apps you haven't touched in months are usually the best candidates to move or offload.

You can sort by it and filter with [Older than](https://storagestudio.us/faq/apps/what-does-the-older-than-filter-do). Some apps have no date at all — see [why](https://storagestudio.us/faq/apps/why-does-an-app-show-no-last-used-date).
