Confidence & risk scoring
Every match is rated High, Medium or Low confidence and given a 0–100 risk score, so you know what's safe at a glance and what deserves a second look.
Dragging an app to the Trash leaves caches, preferences and saved state behind. 1Uninstall traces every file an app touched, scores what's safe, and removes only what you approve — always reversible.
The scan view · confidence & risk on every file
Drag an app to the Trash and it leaves Caches Preferences Containers Helpers behind — quietly eating gigabytes for apps you no longer run.
1Uninstall traces every file an app touched — and shows its work.
A few of the places it looks
Scan, review the why behind every file, then move only what you approve to the Trash.
1Uninstall reads your installed apps and traces the support files, caches, preferences, containers, saved state, logs and helpers each one scattered across your Library.
Each item gets a confidence level, a risk score, and a plain-language reason it was matched. Safe Mode leaves anything uncertain unchecked, so you stay in control.
Approve your selection and 1Uninstall moves it to the Trash. Nothing is permanently deleted. Restore the whole batch with one click from History.
Tracing, scoring, reviewing and restoring — every part of removing an app, handled with care. Some of it is free; the deeper sweeps are Pro.
Every match is rated High, Medium or Low confidence and given a 0–100 risk score, so you know what's safe at a glance and what deserves a second look.
Low-confidence files stay unchecked by default. Approve them deliberately, never by accident.
Everything runs on your Mac. No account, no cloud, no telemetry — the only thing that ever moves is the files you choose, and only to your Trash.
Surface leftover files from apps you deleted long ago — the junk a drag-to-Trash uninstall left behind.
Review LaunchAgents, LaunchDaemons and privileged helpers that load at login.
Line up many apps at once and clean them in a single pass.
Spot the same app installed in more than one place and queue the copies.
Every uninstall is logged as a batch. Reveal it in Finder or restore the whole thing instantly.
A quick check tells you whether Full Disk Access is letting 1Uninstall see every Library folder.
Schedule a gentle nudge to run a cleanup so leftovers never pile up again.
See exactly what an app left behind — the question you'd ask, the leftovers 1Uninstall traces, and where they were hiding.

Removing files should never feel like a leap of faith. 1Uninstall is built so every action is visible, recoverable and entirely yours — nothing leaves the Mac, nothing is gone for good.
Approved items go to the system Trash, not a permanent wipe. Anything you reconsider is sitting there, recoverable, until you empty it.
Every uninstall is logged as a batch. Restore the whole set in a single click — files return to exactly where they came from.
No account, no cloud, no telemetry. 1Uninstall reads your Library locally and nothing about your apps ever leaves the Mac.
System and privileged-helper files are held behind explicit Admin mode. You opt in, item by item — nothing protected moves by accident.
Each file shows its confidence, a 0–100 risk score and a plain-language reason — so you decide with the full picture, not a guess.
