Both are free to download. Device Tester sells 1 one-off in-app purchase. Disk Space Analyzer & Cleaner asks for nothing beyond the download.
Device Tester holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: Device Tester has 231 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 55% of Device Tester's written reviews are positive against 100% of Disk Space Analyzer & Cleaner's, so the app with the better star average is not the one people write more warmly about.
Device Tester ships an update weekly, Disk Space Analyzer & Cleaner every 10 days. The most recent releases landed on September 21, 2026 and September 13, 2026 respectively.
