diCleaner: what stands out
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools.
diCleaner: strengths
- Storage analysis, large/old files, and duplicate/similar-photo tools
- App uninstallation, leftovers, and startup-item review
- Selection-based cleanup with Trash defaults for most tools
Considerations
- Permanent removal and privacy tools have different effects from Trash
- App Store privacy disclosure lists some non-linked data
- Cleanup eligibility depends on files, apps, and permissions
WhatSize: what stands out
A good fit for Mac users who favor column browsing and integrated duplicate/cleanup tools.
WhatSize: strengths
- Size-sorted columns and detailed filtering
- Duplicate-file tools and cleanup categories
- Updates measurements as the filesystem changes
Considerations
- Paid license after the trial
- Cleanup categories still require your judgment
- Check upgrade terms separately from the initial purchase
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose diCleaner?
A good fit for Mac users seeking free storage analysis alongside broader maintenance tools. Vendor says free to use with all current features included.
When should I choose WhatSize?
A good fit for Mac users who favor column browsing and integrated duplicate/cleanup tools. Vendor lists $14.99 and a 30-day trial; upgrades may be priced separately.
Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
