# One Cleaner vs SmartScanner

The clearest difference is monetization model: SmartScanner at free with in-app purchases against One Cleaner's subscription. SmartScanner also leads on rating (4.7 vs 4.5). One Cleaner's advantage is review sentiment (76% vs 40%) and ratings volume (5.5K vs 1.2K). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. One Cleaner sells 10 in-app purchases, starting at $6.99 per 7 days and SmartScanner sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

SmartScanner holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 5.5K and 1.2K respectively. Written reviews complicate that: 76% of One Cleaner's written reviews are positive against 40% of SmartScanner's, so the app with the better star average is not the one people write more warmly about.

One Cleaner ships an update every 5 weeks, SmartScanner every 2 months. Both last shipped on October 27, 2026.
