Receipts
Free to see, Pro to change
Readings before, readings after, one honest verdict for every action.

What it does
- Compares about 5 minutes of readings before an action with 5 to 15 minutes after.
- Says "Measured" when the numbers moved, "No measurable effect." when they did not, and "Not measurable" when other apps moved too much to tell.
- For cleanups, reports what went to the Trash. Disk space counts as freed only once the Trash is emptied.
What it never does
- Take credit for a change it cannot measure.
- Claim freed disk space while the files are still in the Trash.
Free or Pro
Past receipts stay readable on Free. New receipts come with Pro, because they come with actions.
Honest limits
- Receipts compare two time windows. They are not a controlled trial.
- A small real change can read as "No measurable effect". Hedroom prefers to miss a small win than to claim one it cannot show.
