# CPU vs Scanner

The clearest difference is rating: CPU at 5.0 against Scanner's 3.8. Scanner's advantage is update cadence (every 6 days vs every 4 weeks) and ratings volume (10 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CPU sells 4 in-app purchases, starting at $6.99 per 7 days and Scanner sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CPU holds the better App Store score, 5.0 against 3.8. Both are backed by a comparable volume of ratings — 3 and 10 respectively.

CPU ships an update every 4 weeks, Scanner every 6 days. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
